Opening a Citizen CM 500m diver


Maybe this is the most useless “do it yourself” article ever. Why? Because there are only two more guys I know about that have a Citizen Chronomaster 500m. (Hello Howard and Jose! 🙂 )  There are only 15 watches I found online in all my years of being borderline obsessed with them. I have two and the exact one in this article is available for sale at this very moment.

Anyway, let’s dive right into it!

Let’s pretend you have the watch (congratulation if you do!) and without going to the watchmaker, because you get bored on your Christmas / New Year vacation, you decide you have nothing else better to do than spending your time removing the movement of the most rare and expensive Vintage Citizen Watch ever.

First thing you have to do is have the watch in your hand, remove the strap / bracelet /nato… and look for the right instruments. A watchmaker knife, some tweezers  and a small screw driver, a suction cup and a loupe would be great. As you already know this is a unibody case, so the case back doesn’t come of. This is to further ensure the 500m, eliminating a weak link (the case back).

Use the knife to (carefully) force the bezel out. Just stick it under it (I use a small cotton fabric to wrap around the blade so I can protect the watch from scratches) and put a little force using the lug as a lever. It will pop right out. Be careful not to lose the small metal spring that is located in a small space and inserted in a hole at 4 o clock under the bezel. It is there so that we can have the unidirectional 60 clicks action of the diving bezel. Then remove the tension ring that holds the crystal, using the same knife. No fabric this time because there is no space. Take your time, it is not difficult at all.

Because you already have the suction cup, just use it to lift the crystal. Something sticky will do the same thing. Now use the magnifier and the tweezers or / and the small screwdriver to remove the dial bezel ring and the rubber seal that is under the crystal. Good! Now unscrew the crown, turn the watch face down and rotate the crown…. the movement will fall! Be careful on what it falls onto and do not touch the dial or bend the hands. If you want to make sure this doesn’t happen you should remove the hands before turning the watch dial side down. (that is for a different article).

Congratulation! You did it!

Now, put it back together! LOL!

Choosing the perfect watch for Baselworld 2018


In just a few days I will be at Citizen’s 100th Anniversary Party at Baselworld. Proud to be invited at this special, once in a lifetime, event. So… which watch should I wear?   I have to take so many aspects into consideration when making this decision: first of all, it should be an important watch in Citizen’s history, a rare one, a cool conversation piece, one of my best… Also, I have to think about the way I dress, about the over 12 hours drive to Basel, the weather maybe? Hm…. Tough choice! 

In order to decide I created a POLL on Vintage Citizen Watches Facebook group and here it is what my friends think I should wear:

Third place: The Citizen Glorious

The 1971 Glorious is one of the rarest and most appreciated Vintage Citizen Watches. It is not called “Glorious” for nothing. At the time of its launch it had one of the most precise and accurate movements in the world, and many say it was a lot better than the direct competitor: the best of Grand Seiko line. Awesome 36,000 bph movement, no doubt about it, perfect SS case finishing, NOS, a pride to have in such condition. Does it get any better? I would love to have it with me at Baselworld!

Second place: The Citizen Diamond Flake

The 1962 DF is so much more than a beautiful watch. It was, at the time of its first appearance, the thinnest three hands watch movement in the entire world, at only 2,75mm! This is the ultimate dress watch: thin, elegant, no date, no lume, manual wind movement, silver dial and…. let’s not forget that my example is made of solid white gold!  Talk about class! What better choice for a formal Citizen party?

First place: The Citizen Chrono Master 500m

This in my Holly Grail, one of my pride and joy watches, the 1969 beast diver! The best of the best! Would I strap this on my wrist, hell yeah! Is it a good watch to wear with a suit? Maybe it is not, but look at it, read about it and wear it! I wrote a lot about this awesome watch and no more words are needed, this is the “to go to” watch at any Citizen get together. But is it the best option for this occasion? My Facebook friends think so and this is still to be decided in the next day.

And a special mention, on of my favorites:  THE Shokosha Citizen 

Somehow this simple pocket watch went under the radar but think about it, after all it is the 100th Citizen anniversary and the watch that started it all, the first, the one to be celebrated here is in fact this one, the one and only, THE CITIZEN. So why not more votes for this one? I would vote for it and in fact I will right now and give it a chance!

The battle is on and one of these will go the 2018 Baselworld  for the 100th year anniversary party. So… which one should it be?

Will keep you updated. 😉

The fabulous story of Seppo and his B52806 150m Citizen


I had a dream – a dream about watches, adventures and open waters. I had a dream about freedom, and friendship, about trust, duty and honor.

It was the late ‘60s – a time of change. We had the moon landing, not because it was easy, but because it was hard. We had the Beatles and Bob Dylan. We experienced Woodstock, raced cars with naturally aspirated roaring engines, smelled the burning rubber and the exhaust gas. We watched Paul Newman films, surfed under the So Cal sun or enjoyed a glass of vino rosso somewhere on a hill in Tuscany.

Freedom, adrenaline, sex, innovation.

I had a dream about the time when a watch was so much more than jewelry, when its purpose was to indicate time and it was used in the way it was always meant to be: racing, diving, flying or timing important events, even in space or on the Moon.

Yes, I’m talking about tool watches!

In the picture above is me, diving, and Seppo wearing a shirt with the logo he designed. In the background we can see the watch. 

It was the late ‘60s and the world was experiencing major changes. Somewhere in Mariehamn (read about this place HERE), Seppo Prepula was also about to have a change in his life. He found himself in sudden need of a new watch.

As he was walking home from work on a cold day, he noticed heavy rain clouds forming overhead. He picked up the pace but it was already too late. The notorious Finnish weather caught up with him, setting in motion the events of our story.

He got home soaking wet, down to his Omega watch. He was not happy.

Two years ago he’d started taking diving classes at the local fire department in Hanko. He’d been bitten by the diving bug and decided that the obvious, natural thing to do was buy a diving watch. His old watch was now ruined, which only motivated him to follow this path and make no compromises in his choice.

He’d heard about a Japanese company called Citizen, that offered high quality diving watches. So he entered a store in downtown Mariehamn, had a brief talk with the seller – who proceeded to throw the disaffected Omega in the trash – and decided on a new Citizen diving watch, the 150m B52806.

That very watch is on my wrist as I write this article.

Here is the watch, the way I received it, caseback and movement too, before cleaning.

Before sending me the watch, Seppo described it “practically new”, and he was so right! The beauty behind this statement is amazing. Even though time took its toll on the crystal, even though the lume is yellow and some of it is gone, even though the case is showing so many deep memories and the crown no longer screws back in… Seppo is seeing it through the same lens he did the first time he laid eyes on it. What Seppo sees when he looks at the watch is his reliable diving buddy.

Yes, Seppo, I can confirm… the watch is indeed “practically new”. Thank you so much for allowing me to wear it with pride, to keep it and enjoy it as you did.

Now back to Seppo and his story. A few weeks ago, his son, Conny, wrote a comment on my site www.vintagecitizenwatches.com telling me that his father has an old diving watch and inquiring about its value.

Well… the rest is history and here I am wearing it today as I tell its story. Between the years 1960 and 1990 Seppo did a lot of diving. Today he is 76 years old and his son Conny is 46 (younger than the watch). In fact, it seems highly probable for this watch to have been at his father’s wrist when Conny was born. Seppo wore it almost all the time, rain or no rain, and, of course, when he was diving. That was, after all, its main purpose. And he dove all around the north European seas. All his life revolved around this passion. He used to wear his special knife, looking – as Conny recalls – just like a Jedi master.

Some personal pictures of Seppo, diving and wearing the watch, the club logo and the watch on the strap he used for diving. This is how I received it. 

He started diving in 1967 in Hanko, near Mariehamn before he moved to Uusikaupunki where, with the support of his diving buddies, he founded a diving club. That happened in 1978, the year I was born. He also designed the club’s logo, which is still in use today. Visit the website HERE.

He remembers one of his first dives in 1968 at the Plussa wreck, where he uncovered a sextant and a helm. These artefacts are now proudly displayed at the Mariehamn Maritime Museum. Read more about it HERE.

In Bomarsund, he dug up cannons and a lot of brass/copper ammo core as well as plenty of old cannon powder, stored in tubes (“I enjoyed these in the late ‘80s and almost lost my eyebrows a couple of times because of that, says Conny”) Read about it HERE. Ten kilometers north of Bomarsund, in the early Swedish times, dives were organized to mine for silver and rock crystals in the remnants of the old mine.

The watch reportedly reached a maximum depth of 70 meters (WOW!) in front of Eckerö Post & Tullhus of Åland. Eckerö’s post operated in the time of autonomy as Russia’s westernmost border station for Sweden over a hundred years, which is what made it such an interesting place for diving. The wreckage remains hidden somewhere in the deep waters and will one day for sure be discovered. Read more about Aland HERE.

At Herrö, many dives were made to the wreck of Skiftet. They were sludge cleaning the wreck and lifting up items from it. In one of those dives, Seppo’s regulator got stuck somewhere in the engine room and he had to take his tube and gears off at a depth of 25 meters. “Small close call issue”. Read more about it HERE.

A lot of grenades and ammunition were saved in the seas in front of Hanko – read about it HERE. Read more about the old Mannerheim coffee house HERE.

In the late ‘70s, Seppo was part of a group of divers searching for bombs off the Hango coast. Seppo dived, located grenades and marked them for explosion. They were old Soviet grenades left there after Soviet occupation in WW2. Seppo and his family also lived in the region for a couple of years.

In the early ‘80s at Uusikaupunki, a 300 kg anchor was raised up in front of Lyökki. It now belongs to the Uusikaupunki Museum. “I remember that trip when I was a young boy, my father was with a 6-member diving team that made this job at a depth of 40m”, Conny recalls.

The watch made its last dive in the early ‘90s, when Seppo was tube-diving in the factory of Uusikaupunki.

Diving locations and expeditions, the anchor he saved (wearing the watch) and other items, the medusas rising, the blue seas…

Well guys, if this is not a real tool diving watch, show me a better one! I almost ran out of words working on this article. There is a huge amount of pressure on me as I try to do justice to this special timepiece and its fascinating story.

Seppo recalls that the movement of the watch was only serviced once, in 1975 when the bezel insert was changed because the old one was so deteriorated it was difficult to read. This could have been a safety hazard when diving so a new one was installed. Back then, the watches were not looked upon as collectable jewelry and were not pampered. It was a diving instrument that needed to be up to the task so the original bezel was thrown away and a similar one (Citizen made, of course, but from the next 150m variant) was installed, having the exact same specifications. After this, the watch was never opened nor cleaned until the day I received it. Hundreds of dives in the cold, deep, salty sea waters, and never ever failing once.

Cleaning the watch.

Seppo always trusted his watch to perform and the watch never disappointed him. It was always there for Seppo, keeping him safe.

A few questions for Seppo and his answers:

– what watch are you wearing now? – A “normal” Citizen.

– why did you sell it? And why did you sell it to me? – I am not using it for the purpose it was meant to be used. I don’t dive anymore. I consider that you appreciate the history of the watch and the watch itself, so it felt absolutely right for you to have it.

– how did it feel to let the watch go? – The watch did not have huge emotional ties, but it has been many times involved, most of all it has been a tool for me, which has worked just like a train, always flawless, just like it should.

– do you miss diving? – yes a little bit, I miss this adventure and finding new things, it is difficult to find that view and feel in land, you can try, but you probably need illegal drugs for that. 🙂

– if starting life again, would you do it the same way? Diving, watches… any regrets? – I would not change a day, everything or object leads to something and every item is correct in time, it does not change anything by switching. I could live my life 100% same way.

-any advice for someone who is looking for his first watch, that is just starting his life? – I myself know that a mechanical watch is the best and safest solution for underwater use. Water and electricity do not belong together!

– what is the best memory you have (when wearing the watch)? – Underwater “adventures”, the watch told me that this does not have to be left up yet. Also friends, we were a close community and we always take care of each other’s safety in diving on our trips. Great memories are those summer dives when the medusas rise abundantly in the upper layers. The sight is beautiful and it is worth experiencing at least once.

-what other watches did you have at the same time with this Citizen? – Omega and Leijona, only needed one dive watch and it was this one.

-how did you get this strap for the watch? Did you wear the watch with this strap when diving, or other similar ones? – It is a compass strap (Suunto, from 80 “s). Originally bought a stretch of metal bracelet, it quickly began to resound, obviously salt water did their job to it.

– what would he like for me to do with the watch? Wear it? Take it diving again? Keep it in the safe with my collection? – Please keep maintaining the watch and its history, I greatly appreciate it is in the hands that know something about it and know that it’s real tool not just a cosmetic jewel. Enjoy it!

Thank you Seppo! I can’t thank you enough! I am humbled to and grateful at the same time for the honor to write about you and about your watch, well… my watch, OUR watch! Somehow I feel I am a part of your adventures and hopefully the readers will appreciate it as much as I do. Thank you!

Seppo’s watch and a NOS one I had in my collection that was lent to me by his present owner for this  photo shoot.

All things considered… This was no dream; this was the reality even though this is the dream watch we all hope to find one day. If you have a similar story to tell about your beloved Citizen watch, please let me know, or if you know someone willing to share his story, please write me, I would love to write about it. I hope you like it!

Thank you Seppo and thank you Conny!

UPDATE 2019 – This must be one of the most special watch related stories ever! One year later… I received in the mail a gift, a watch. It is a Pook watch, and let me tell you why is it so special! Well.. long story short… the Pook Watches was founded by Andreas, the son os Seppo! He was inspired by my passion for Vintage Citizen Watches in general and divers in special, he was touched by his father’s story and blending all these with his love for diving… he created this awesome watch! So… give them a try! Here is the father’s watch, the Seppo diver, and the son’s the Pook, both mine and here to stay! 🙂

And now… it is diving time!

FINAL UPDATE AND THE PERFECT CLOSURE, 2019 – CHRISTMAS – Yesterday night I had another dream, so, as soon as I woke up I wrote my friend Andreas (Seppo’s son and the creator of Pook watches) that I would love for him to have the watch back. It feels like this watch should stay with him. After all, this is the watch that started it all, so… this is why the watch will be back to where it belongs before Christmas. I am so happy and blessed to have had the opportunity to take care of and be the custodian of this awesome watch for a year and a half but now it is time for me to say good bye and return it to the right owner where it truly belongs.

Thank you so much Andreas and thank you Seppo!

Vintage Citizen Watches case finishing


We talk a lot about watches because we love them. We love to strap them on our wrists, to wind them, to play with the chronograph, to turn the bezels. We enjoy to hear them ticking and to look at them. Most of the times we appreciate the details of the dial, the fonts, the lume, the movement… But let’s take a closer look at the cases, at the way these cases are crafted and finished.

Citizen watches are made in-house so the cases are also produced by them. It is not an easy task to make so many models. This means that a lot of  tools and work hours are needed. After all it is a business and profit margins should be there and case designing, producing and finishing are resource and time consuming. Let’s not take this work for granted. Today I will present to you three different watches. I chose one chronograph, one diver and one dress watch. The best of the best (in my opinion) when it comes to (not only) case finishing.

1 – Citizen automatic chronograph 67-9357, the octagonal “bull-head”

This piece has a stainless steel case, shaped like an octagon, and has 21 different surfaces, not counting the bezel. It is a combination of brushed and mirror polished ones. The top part (where the crown and the pushers are) is brushed laterally while the front part has a longitudinal finish. All the rest is polished. So manny angles and the way that the top part flows, from the powerful top part to the organic lower one! Lovely! This is for sure my favorite chronograph case!

2 – Citizen Super Autodater 39J 150m Parawater SADS52801-Y

The diver! The professional one, the first 150m with this design language. Well… this is the only uni body case 150m. This means that the movement comes out only if you remove the bezel and the crystal. Then you can remove the movement. The case-back is part of the case and it does not come off because it is safer this way when diving with it. After all it is the Professional one. All the case is polished, except the top part of the lugs. Now look at those lugs! Art! Just look at the beveled edges and the precision of the polishing. Perfect sharp edges everywhere. What a shape!

3 – Citizen Glorious

I can talk all day about it. After all, it is THE Glorious!  Just look at the pictures and realize that they just don’t do justice to the watch. In reality it is much better. And together with all the other details, the crown, the case back GC gold inlay, the GC stainless steel signed buckle… mesmerizing! So clean, so powerful, so confident without being over the top. All the precise lines and angles, the edges, the compact elegant shape… Yeah, I know that I am stating the obvious so I will better end it here and let you magnify the picture for better understanding the beauty of VCW.

As a conclusion, I will let you have it your own after you click on the picture and magnify it. Also click on the links above to read more about these models, you wont be sorry, but I have to warn you… it is contagious and soon you will find yourself craving for more Vintage Citizen Watches. 🙂 Enjoy!

Power, spirit watch


So why do I Really wear this? What is it that compels me to cast my eyes across the many models I could choose from, only to succumb to the subconscious needs to wear what I believe to be the holy grail of watches? MY Holy Grail! I questioned whether it was the subconscious strength It offers me, or the empowerment it affords me the instant it hits my wrist.

That sense of power it transfers to me, offering such irresistible desire that you just have to take a sneak look at the timepiece when you think nobody’s watching? The hidden comfort it affords, the metamorphosis of cold steel to skin temperature the instant it’s put on. There’s so much I could say about it, so many reasons to give to justify wearing what I openly concede to be MY holy grail of watches.

The finest of nuances are what does it, the 60 clicking sounds of the bezel so finely crafted, the hypnotic power of the second hand as it moves effortlessly in it’s attempt to put me into metronomic trance. Yes, that’s it; it’s my Spirit Guide, my guardian, and my keeper of time. Time we all know rests so precious upon one’s hand.

It is… The 1969 Citizen “Chrono Master 500m Diver”, of which there is nothing to compare!

citizen 500m chrono master diver vintage

It is a piece of such importance to me I can safely say it’s the one! The Grail, one that none other will ever beat! Truthfully, the realist in me accepts that one can never give a closed title to any watch, there will always be another to come and steal your heart, your soul, your very being.

Why did I not choose the predictable, the Rolex Submariner, or some other grandiose watch? Because nothing else could give me the story a watch should give. (Read about the Citizen 500m Diver HERE ) I’ll tell you why? I simply couldn’t. Even with all it entails, the Rolex to me can never capture the sense of spirit that is held in the above. You see buying a watch isn’t always about money. Anyone with money can buy a ‘Rolex’, but can they buy the passion of the story behind it? In my case it can’t.

Yes, it’s true you have to posses some level of wealth to obtain the Citizen 500, but that isn’t always enough. You have to possess fortune, luck, a blessing, call it what you will. I call it fate. This was destined to become mine, my keeper of time.

Having that knowledge I’m in possession of my guardian angel I no longer fret or worry about when, if, how am I ever going to get my hands on such a treasure. I already have, and that’s the strength behind my loyalty to this particular model. Waiting patiently sometimes not so, I knew my time would come, and come it did. My waiting paid off, and many a lesson learnt in the process of my waiting.

I was taught the concept of perseverance, the will to fight, to never give up on any given cause. The watch is more than just a watch; it’s my journey. A journey that saw several watches passes through my grasp. But my perseverance paid off; for despite those few for sale over the time; with only two of these being 100% original, (needless to say I bought them both…) That is why I award my Citizen 500 the title I bestowed upon it.

There will never be another watch, or brand that will replicate the feelings I endured during my quest to own the Citizen 500, the thrill of the chase, the disappointments, the ultimate euphoria I felt when I eventually took possession of my cherished goal. It is what encompasses the very self of me, my spirit, my determination, my very soul. My spirit went into the chase for my Mecca of watches, the reason I now call it ‘my Spirit watch’. It holds the very essence of me which when I look at it on a daily basis I’m constantly reminded of.

This watch will be carried with me through the rest of my journeys. It will experience the thrills I’ll no doubt encounter when looking for another prey in the ever-growing desire to build the best Citizen Vintage Collection possible. It will never have a price tag on it, never be for sale, it is mine. It is my Spirit Watch.

Crystal and bezel insert Citizen 150m diver


One rather simple task is to change the bezel insert. I will update the article with info about how to do it. The crystal changing can be an easy one or not really, depending on the model.

In this case we removed the old scratched crystal and replaced it with a better one and this really made the owner say that the dial is gorgeous. Finally he can appreciate the beauty of his watch.

The bezel insert was changed with an aftermarket one that is very close to original specifications. Lume is a good match too.

Both the original crystal and bezel insert were returned the same day to the owner.

A simple cleaning was carried out, of course, and we identified a few problems: the frontal part of the lugs were polished and they are supposed to be brushed and the movement needs cleaning and new seals. This will be carried out in the future.

I hope you like the result! 😉 The picture shows the reflections on the crystal.

Now, strap it on a nato and enjoy it! 😉

Citizen parts for repair and restoration


At least once a week I get a mail, a comment or a message about sourcing a part for someones loved vintage Citizen watch. It may be a missing bezel insert or an original crystal. Someone is looking for a movement part for a Jet calibre or for Chrono Master hands. Maybe you are searching the original Citizen diver strap or a bracelet link to buy in order to restore your watch.  We are all looking for something… So: where can we find original parts for our vintage Citizen watches? Is there a special secret place for them?

citizen parts crystal bezel crown for repair and restoration

That is an easy question but not an easy one to answer. In fact original parts are, most of the time, almost impossible to source. Citizen company doesn’t provide them (because they don’t keep them) and because they made so many models I imagine having all available is not a real possibility. So the company is out of the question. Next choice would be looking for one online. But… do you know the part code? I guess you don’t. So first thing you have to do is finding a Citizen original parts catalogue, find the part inside and find the identification code and then search it online. Even so, finding one is close to impossible again. The chance would be for the seller to know the part code and listed with this in the title, and that is not really going to happen, is it?  😦 What else do we have? Watchmakers… there is not even a slim chance your watchmaker can have the original one unless you live in Japan and  your watchmakers father was a watchmaker too, that worked for and with Citizen and has a lot of leftover parts in his attic. Yeah, I know… slim chances you are ever going to find that part this way. Another choice is to ask me. Yeah, right. Unless you want a bezel, a crown and two crystals I am actually basically useless. (update: I gave them away too so I have no more parts)

How to do it then? Your best bet would be to find a “donor” watch. That means finding a junk watch that has the part you are looking for, buying that watch and get the part. Of course, keep looking online for your original NOS part, you might get lucky in a month or maybe a few years… or probably never.

The last choice is to go for aftermarket parts. First find a good watchmaker, than see what he can do to help you…

Conclusion? Keep looking (day and night)… you can never know when you will find the needle in the haystack. Good luck!

Citizen Jet Autodater 120m – the first diver


It is always nice to know which watch was the first, the thinnest, the most this or that… It is extra nice to have one of each. With Citizen that is not so easy because there are so many models! One of the most collectable lines is the one of the diving watches, so which is the first real diver that Citizen made?

The first Japanese water resistant watch was the famous Parawater, launched in 1959. You can read about it HERE. But, that was not a real diver. In fact the first diving timepiece was this one, the one in this article, the Jet Autodater para 120m water. At about the same time another model was made, the Autodater 200m , the skin diver. Read about it HERE.

Here it is, the Citizen Parawater 120m Jet Autodater (ADRS51301-DA)

citizen jet auto dater 120m

Unfortunately the manufacture date can not be easily determined because there is no serial number but it is estimated to be somewhere around 1962 . Find out how to date a Citizen HERE.

The case is made entirely in polished stainless steel, with a screw in case back and a bidirectional friction type bezel. The crown is non screw in. The water resistance is obtained by using a rubber O ring and it is enough for 120m. Not bad I would say. 🙂 The acrylic crystal is domed and gives it a vintage feel. The dial is black, with luminous large trapezoidal hour markers and steel hands. The hour and minute hand have a black tip with a luminous central line where the black part is. The black painted bezel has a luminous dot at 12. On the black dial we see the date, located in a traditional way, at 3 o’clock.

The movement is a 19 J jet caliber, no hand winding. The date changes by advancing the hands pass midnight and back to 21, and again midnight… It is not a quick set date. The seconds don’t hack. So… not a phenomenal movement but one of my favorites. (the Jet – with a ring rotor and you can read about Jets HERE) This one is one of the earliest types, with no hand winding. Just a tool watch with a simple, robust movement.

citizen jet auto dater 120m

The strap that completes this awesome watch is a Tropic rubber one. Perfect match! Now, all I have to do is strap this piece of history on my wrist and take it diving! Well.. desk diving. 🙂

Citizen Crystal Seven para100mwater diver


Exactly one year ago I wrote about a fabulous watch, the Dandy Seven diver (read about it HEREand here we are today talking about it’s brother, the Crystal Seven diver. They were made in the same period, they share the same line (Seven), the same movement, and the same style, but each stands proud as powerful individual watch.

crystal seven vintage citizen diver

It is a decent sized watch, with a modern look and a strong vintage feel; maybe it is the shape of the case, maybe the colors, maybe the entire watch. By the way, it is made entirely of stainless steel. The SS bracelet I doubt it is the original one but it suits the watch very well, with those blue highlights, that match the minute chapter ring color perfectly. The front part of the case is brushed while all the rest is polished.

It is a diver watch (para 100m water) and as any diver watch that respects itself it has a bezel. This one is an aluminum bidirectional friction type with a luminous dot on 12. The dial is beautiful, grey, with a sunburst effect. The hours are marked with luminous material. The hands had luminous parts too but on mine they must have fallen out and to this day it was not yet relumed. The second hand has a luminous ball too. The minute chapter ring is blue with white 5 minutes dots.

The movement inside is the Citizen automatic 5204 calibre, with 27 jewels. It can also be winded by hand. The winding crown is made of stainless steel and signed CTZ. It is not a screw-in type. Due to this movement, the watch displays both the day of the week as well as the date. The day changes by advancing the hands past midnight while the date changes normally in the second position of the crown. The movement doesn’t hack.

One thing that differentiates it from it’s brother (the Dandy Seven) is the mineral crystal (hence the Crystal Seven name). On the other hand, Dandy Seven it fitted with an acrylic one.

All things considered it is a beautiful, rare diver, vintage and somehow modern at the same time.

Citizen Diver OR-O B52806 or 62-5370 are, more or less, the same model. Both of them are difficult to find, no matter the condition, to find a NOS one… almost impossible. The 62-5370 is made for domestic market and the B52806 for export and has its own awesome engraved case back. So, they have different case backs, different hands sets and dial codes but they share some of these features sometimes (variants or marriage?). The second hand tip received a luminous ball for better visibility for the export model. The 62-5370 can be found with a simple second hand. The only obvious thing that is constantly different is the case back. The movement is Citizen cal. 5470 for 62-5370 and 5430 for B52806. I don’t see any other difference between these two calibres other than the swinging rotor.

I had to have both of them even though in the first place I got only the NOS export model (because of the beautiful case back).  Both of them are marked water proof 150 M in a period when the term Parawater was about to… unfortunately disappear. This water resistance is possible due to thick mineral crystal, screw in crown and case back. They ware made in ’69-’70 but the exact period is impossible to determine for the export model because it has no serial no. The 62-5370, on the other hand, has a serial engraved and the manufacturing date can easily be seen.

So… one model with variants or two distinct models? The debate might still be on but as far as I am concerned I will consider them variants of the same model and… have them both!
