Citizen diver 150m 52-0110 dial variants


The largest group of Citizen divers is the 150m one. It has a classic design and a gorgeous look. They had a production time span of about 15 years, powered by a handfull of movements. The last model was the one in this article, the 52-0110. Even if this is one model it had a few variants. I saw only black dialed versions and a rare orange dial one. Stephen on his page suggests it might have had a blue dial too. http://sweep-hand.org/citizens-vintage-divers-1962-to-1980/ I have yet to see one to confirm that.

No matter the color, we can see two design variants, one prior to 1978 and one after 1978. I will call them “type 1″(8210 820719-S) and “type 2” (8210 824391 KA). The dial code is printed on the dial at the bottom of 6 o’clock. I am lucky enough to have both of them. Let’s see the picture that can be magnified them for better understanding.

citizen 150m 52-0110

My type 1 was made in ’77 and type 2 in ’78. The case is the same, the crown, crystal, bezel and movement are the same. Both powered by the well known Citizen cal. 8210, 21.600bph, quick set date, non hacking seconds.

The main difference is the dial, and the way the hour markers, the logo and the date frame are made.

  1. Type 1 has the letters of the Citizen logo separated while type 2 has all the letters connected in an applied logo.
  2. The date window on type 1 is connected with the lume frame. By contrast type 2 has two distinctive parts, date frame, and lume frame.
  3. These is due to the way Citizen chose to manufacture the dials. Starting from ’78, on type 2, they decided to apply these elements, and so they did. They made the dial, painted it, printed the white lettering and the minute markers and later applied the logo, the date frame as well as the hour markers.
  4. In type 1 (prior to ’78) we have a unibody dial, made in one piece containing the logo, date frame and hour markers. After painting and printing it Citizen polished the surface revealing this look.
  5. Under magnification the main difference is easy to spot: Type 1 has polished elements with only one metallic surface appearance while type 2 had these elements polished  on the sides too. This is because they were never painted. On type 1 we can see the black paint on the sides of the logo, date frame and hour markers.

With Citizen most of the times the look of a watch is dictated by the manufacturing process and so is the case with these dials too.

Citizen Crystal 7 – 33 jewels


Among the interesting vintage Citizen, this one has it’s special place.

It is the para water Crystal 7 with 33 jewels and a uni body case.

citizen crystal 7 33The watch is the perfect size for a dress one, not too small, not too large just as it should be even by today standards, at 37mm diameter. The case is elegant, entirely polished, made in one piece of stainless steel. That means that the case back can not be removed and the movement comes out only by removing the mineral flat crystal. This is a nice feature that makes the case a little more water resistant by eliminating the risk of water entering the watch through the back. Because the case back is the same piece with the entire case it is possible to place the beautiful engraving in such amanner that it is always crown side up. This is a nice bonus to the overall look of the watch. The engraving shows the water resistance by “para water” marking and the uni case body is marked by a small “x” inside a small circle. The model is ACSS 51401-Y and was made in April 1966.

The dial is silver, with a sun burst effect and a lot of applied markers. The hour markers are applied, the day and date frames are applied, the Citizen logo, the 7 logo and 33 marking are also applied. The “Crystal” writing is in black and so are the minute markers. The hour markers have a longitudinal black line just as the hour and minute hands. The overall look of the face is beautiful, silver with black, elegant accents. The only color used is the “SUN” in Sunday on the day wheel.

citizen-crystal-7-33 copy

The movement is the automatic (hand winding is also possible) 33 jewels Citizen cal 5204 ? , beating at 18,000 bph. It is a quick set date while the day changes by advancing the hourhand past midnight. It proved to be very good at time keeping; some people even say it is very close to Chronometer grade and Citizen Chronomaster line.

The strap is a replacement black leather Citizen strap with a simple stainless steel tang buckle. I think it fits the watch and adds to the overall elegant look.

Beautiful, elegant, classy day-date vintage Citizen.

Citizen Chronomaster 500m Chronometer


This is THE holly grail of Citizen collectors! This is one of the most sought after vintage watches! This is my dream, my so long waited one and the answer of all my intensive searches!

People ask me where did I find it? I am going to tell you the story of finding this one.

I started collecting vintage Citizen a few years ago. (I write this article in 2015 February) I always loved divers and chronographs. The first watch I had as a kid was a blue Volkswagen quartz “diver”. I still have that one.  Then as time passed I found myself over my head into buying and selling, repairing and loosing money because of my passion, reading, writing, comparing and… you know… collecting. 🙂  I learned that there are fakes, aftermarket parts, interesting watches and common ones. I found out what I like and tried to let the other watches go. I learned not to buy only because it is a good price. I learned a lot and I am still learning. Then about two years ago a piece of information came to me. It seemed that there is a certain diver made in stainless steel, Chronomaster, 500m WR, Chronometer grade. So I started looking for one.  Sometimes I dreamed about it, sometimes I thought I found a lead but time after time,  it was just a mind trick. In all these years I searched for one each and every day. I found four so far. I bought one. The first one was sold as “junk” in Japan for USD 4.100. The second one I found online, on a watch forum, and has a replacement bezel and bezel insert and is not for sale. The third one, on facebook, has a replacement crown, bezel and bezel insert and non original strap and is nor for sale. The fourth one is my watch.

One month ago (2014 December) I was on a trip in Hong Kong and of course I had my share of watch hunting. So I found a vintage watch store that had an Alarm Citizen. I asked if they had any other Citizen and was told to return tomorrow. They will look for more in the back of the store. This is what I did. The next day I saw 5-6 watches and got myself THIS Citizen Leopard. I got the watch and went to dinner. Waiting for the food, I google searched the serial of the Leopard I just got. I might have entered the wrong digits because one among the images I found online showed a Citizen 500m. There was a new image that I didn’t see before. I clicked it. Imagine my surprise when I found that the Chronomaster was for sale in Japan, posted one day before! I tried to translate the page on my mobile and contacted the seller. They were not selling outside Japan. My world tumbled down! I wrote on my facebook page asking if maybe I have some friends from Japan. Eric said yes! So I wrote him. We never spoke before that day but now we are good friends. Thanks Eric! He said he was willing to buy the watch for me and send it my way. To make a long story short, I sent him the money, he contacted the site where the watch was sold, the site contacted the seller, the seller sent the watch to the site, the site said the watch is not ok and maybe they will cancel the transaction if they can’t solve it. The watch was running fast but I didn’t care. Eric said that if they don’t fix it they will not send it. I worried and I waited. What was I supposed to do? Nothing. It was not in my power. A few days later Eric had the watch! Then the watch was on the way to me. 🙂 Let me tell you that the original pictures of the watch were of a very poor quality and I had only a vague idea about what I was buying. Later I found out more information on the watch by talking directly to the seller. This was a very difficult task to achieve. Not easy to find the original owner, trust me on this one. 🙂 So, the only info I got is that the watch came from Kawaguchi, Saitama, Japan. I hope I will find out more. (I found nothing more – 2017)

So this is what I got:  A huge 44mm one piece stainless steel case (uni body case – the movement comes out through the frontal part of the watch, after removing the crystal and the bezel of course), thick slightly domed mineral crystal, unidirectional 60 clicks bezel, screw in crown, rubber strap marvel! I got the whole package! One thing I found (June 2017) is that the eagle engraving on the back is not actually directly on the case but rather on a steel inlay (like the gold inlay used in the dress Chrono Master) I didn’t remove it but I am quite sure I am right. Anyway, back to the story. 🙂 My watchmaker opened the watch only to find a perfect movement as the one in THIS Chronomaster (but Chronometer grade – Citizen 5440). Everything works as it should! I am so happy!

Well… the hunt is over, the dream has come true, the wait was long. I am tired and so happy!

Thank you: Eric (Japan), Stephan (UK),  Jack (Singapore), Fred (Austria), Daniel (Germany) for all your contribution. You all have your part in making my dream come true! Thank you my friends!

Update 2016: Here is another one. 🙂 So I have two now. (Well… I sold one to have the money for the other Grail, the Glorious – 2017)

citizen 500m chrono master diver vintage

Update 2017: Hard to believe but I found another one for sale in Japan (the best condition I saw, really beautiful!) (pictures below and all credit for them to the seller – Kyotoya – Japan) This one was made in January 1969, the first production date I saw. Here it is:

Update July 2017  – I bought and instantly sold another one, the first serial January 1969, never polished, 100% original. Here it is:

Conclusion 2021 April:

In all the years of hunting these watches I saw only 23 pieces, in private collections or online. I had four of them. Putting together all the serials and details the conclusion so far is:

  • 11 of them are made in April 1969, 1 made in March 1969 and 4 are made in January 1969 (901006xx) (I cant see the serial of the other 7 in order to date them)
  • there are two dial variations: “CHRONOMETER” & “Chronometer” Why?
  • the “Chronometer” variant has an aging yellow lume. The other remains more green.
  • the April serials range is from about 90400420 up to about 90401130 (except the January 69 pieces, the first one being is 90100xx and the March one) How do the last 5 digits of the Citizen serial actually work ?
  • the finishing of the case  – all brushing should be longitudinal, only on the top part of the case
  • they came on 20mm straight end Tropic straps (with Citizen signed buckle?)
  • there is one collector in Japan that has four pieces, I also had four but only two at the same time. I have one now.
  • based on some of my sources it seems the total number of watches produced is probably 500, (500 for 500m) most of them probably are thrown away in the trash. We tend to forget back then watches were not collectable as they are now.
  • the reason why they were made was because Citizen had something to prove, the reason they stopped making them is because they made the statement and proved it. They made the best diver. The rest is history.
  • no parts are available or will be available.

Underwater Diving Watches Quartz War


The Quartz Crisis, (also known as the Quartz Revolution), is a term used in the watchmaking industry to refer to the economic upheavals caused by the advent of quartz watches in the 1970s and early 1980s, which largely replaced mechanical watches. It caused a decline of the Swiss watchmaking industry, which chose to remain focused on traditional mechanical watches, while the majority of world watch production shifted to Asian companies that embraced the new technology.

On 25 December 1969, Seiko unveiled the quartz Astron, the world’s first quartz watch. The first Swiss quartz analog watch—the Ebauches SA Beta 21 containing the Beta 1 movement—arrived at the 1970 Basel Fair. The Beta 21 was released by numerous manufacturers including the Omega Electroquartz. On 6 May 1970, Hamilton introduced the Pulsar – the world’s first electronic digital watch. In 1974 Omega introduced the Omega Marine Chronometer, the first watch ever to be certified as a Marine Chronometer, accurate to 12 seconds per year using a quartz circuit that produces 2,400,000 vibrations per second.In 1976 Omega introduced the Omega Chrono-Quartz, the world first analogue/digital chronograph, which was succeeded within 12 months by the Calibre 1620, the company’s first completely LCD chronograph wristwatch.

quartz crisis Citizen divers(two prints from 1977 and 1979 of Citizen quartz and automatic diving watches side by side)

By 1978 quartz watches overtook mechanical watches in popularity, plunging the Swiss watch industry into crisis while at the same time strengthening both the Japanese and American watch industries.  As a result of the economic turmoil that ensued, many once profitable and famous Swiss watch houses became insolvent or disappeared. The period of time completely upset the Swiss watch industry both economically and psychologically. During the 1970s and early 1980s, technological upheavals i.e. the appearance of the quartz technology, and an otherwise difficult economic situation resulted in a reduction in the size of the Swiss watch industry. Between 1970 and 1988 Swiss watch employment fell from 90,000 to 28,000.(wikipedia)

At the same time Citizen was carrying it’s own war. Prior to this era the company was developing a lot of movements and interesting complications. Citizen production of quartz oscillators begun in March 1976 so the prints above are dating to the very heart of the war. Read more about Citizen history HERE.

So, who won?!

His and hers Citizen alarm – diver style


Here is of my favorite vintage watches! What can I say, I love diving watches! Despite the fact that it is not a real diving one, it is made in this style and has an added bonus complication.

As one can clearly see, because is written on the black beautiful dial, in white lettering, this is an alarm watch, Citizen 63-7076. It is powered by the usual Citizen alarm date calibre, 3102 (engraved underneath the balance wheel). This is based on the USSR calibre AS 1475. It is a manual winding movement, with 21 jewels running at 18000 bph. The watch has two crowns , signed “C”. The top one is for setting and winding the alarm while the bottom one is for setting the time and date and also winding the movement.

citizen diver alarm 63-7076The entire case is made entirely in stainless steel, the bezel is bidirectional frictional type while the crystal is domed acrylic with a date magnifier on the outer surface. I enjoy the fact that the watch looks good on any kind of bracelet or strap you throw at it (nato, rubber, leather, mesh…) Of course it looks good on the Citizen bracelet too. 🙂 The caseback is snap on type and for the alarm can work it can be placed only in a certain way. The active part of the alarm from the movement engages the passive part (the pin) of the caseback only if the two parts fit as they are supposed to.

citizen alarm diverCitizen also made one for the ladies, so here are a few pictures I found online on e-bay posted by antiquewatches-de. This one is a smaller watch and doesn’t have a date (calibre 9812). The crowns are signed “CTZ”.

citizen alarm diverThis year, and the previous one, we saw a growing trend of “his and hers” watches, well Citizen did it so beautifully, 50 years ago! And such a beautiful vintage pair this is today!

Here is a video of another Citizen alarm with the same movement and this is how it sounds:

Citizen Walter Wolf Chronograph


Like most of the times a lot of patience pays off. After a long time searching I have managed to find not one, but two very rare vintage Citizen Walter Wolf chronographs in the very same week! The first one came from Italy, the titanium one, and a week later, the black one came from Germany. (Thank you Fred and Daniel!)

citizen walter wolf

Why is this model so special? Because in the 70’s Citizen produced a lot of interesting watches and their chronograph calibre 8110A was one of the best: fly back, column wheel, day-date, hi beat automatic. What an awesome movement! And where is a chronograph at home?! In a race! So… Citizen made this Walter Wolf watch, with a special case (the one in titanium was one of the early watches to use this material for cases and bracelets). The other one is black coated metal. It also had a bidirectional rotating bezel, a nice feature usually not used in chronographs. On the outer circle of the dial it is the mandatory race related Tachymeter so the outer rotating bezel is a nice addition. Read more about Walter Wolf Racing HERE.

Back to the watch! The black one is made in 1982 and the titanium in 1983. As I was saying the case is special to this model and by doing this, Citizen managed to obtain a 100m WR. That is impressive. The crowns and pushers are non screw in but the caseback is. The winding crown is hard to operate because it is very small. On the caseback we have the Walter Wolf logo (present on the dial too), the brand, the material, the model and the serial no. The country of manufacturing is obviously Japan. In fact I think this model was made for Japan (all the models I know about had English – Japanese day wheel). The bracelet is well integrated with the case and is the perfect design for this racing dedicated watch. The dial is beautiful, black (there is one more model with a golden dial), with a lot of interesting details (please magnify the pictures for better understanding). The luminous material is made with Promethium 147, a radioactive material. Read about it HERE.  It is marked P-JAPAN-P. The rotating bezel is another interesting feature. This in not the usual diving style one but a countdown type! Note the 60-0 markings. (not the usual diving 0-60)  On top of this there is a cardinal inscription (N E S W) for better navigation, of course!  🙂 The movement is the usual Citizen cal 8110A, a vertical clutch chronograph (beating at 28.800 bph) with column wheel and fly back function. It has a day-date indicator. The rotor is special with a different inscription than the common 8110A found in the other models.

Update 2016 October: (pictures credited to the online seller)

Here it is how the original package should look like. Also note that there is a quartz pair of the automatic chrono. Happy to have the  complete NOS package myself. 🙂

Update 2017 October:

Here it is another variant, the golden dial one, same titanium case and bracelet. Notice the honeycomb dial pattern. In the picture below you can also see the Walter Wolf F1 car.

Conclusion: A special watch, loaded with  features, a joy to wear and use, a pleasure for the eyes and a huge happiness for the heart and soul of the blessed owner.

Citizen Leopard 36000 – model 67-2050


When you say the word Leopard next to Citizen you know this is a special one. 

Why is is special? Read on and see. 🙂

citizen leopard

The first thing you notice when holding the watch is the beautiful mesh stainless steel bracelet that fits the case as a high end modern watch would. The case is stainless steel too and has an interesting oval shape, with integrated lugs. The bezel is polished and so is the entire case except for the frontal surface that has a radial brushed finish. The crown is simple, signed CTZ. Another detail is discovered when seeing the watch from the side: a beautiful arched shape, following the wrist of the lucky wearer.

The dial, seen through the oval mineral crystal, is grey-blue, sometimes more one or the other depending on the light, and very elegant. The hour indexes are applied and so is the day date window frame. The hour and minute hands are dark grey and the seconds hand is white. Why is it white? Because the second hand is special. It is special because on the dial except for the applied logo Citizen and Automatic at 12, at 6 it is written 36000, Leopard, 28 jewels. And this says something about the movement. 🙂

citizen leopard copy

The calibre inside is the Citizen hi-beat parashock 7230, running at 36000 bph.  It has 28 jewels and a beautiful white sweeping central second hand that hacks, it can be winded by hand also and has a quickset date feature. The day is set by advancing the hour hand pass midnight.

A beautiful elegant watch and I consider myself to be very fortunate to have found this time capsule in a NOS state, even though it is made on April 1974.

later edit: I found the watch in the next picture on yahoo japan so the pictures are not mine but belong to the seller. This is the first solid Gold superbeat 10 Leopard I see. There are also a few models in stainless steel and some gold plated Leopards too, but this is the first I see in solid gold. Needless to say it is in perfect condition. The selling price is JPY 350,000.

Vintage 1968 Citizen College Alarm


Citizen has a beautiful range of vintage alarm watches, some of them with date, some of them more simple, like this one, without a date.

vintage citizen alarm

Here is the no date version of the Citizen alarm, the Citizen College Alarm. It is marked Parawater and this fact, along with the serial no, is dating it to March 1968. The design is simple and clean, the case is made in stainless steel, with a domed acrylic crystal. Read about how to date a vintage Citizen here.

citizen alarm vintage

One of the best feature of the watch is the pie-pan dial look. On closer examination the dial turns out to be flat but the two types of finishing and tone gives it this lovely appearance. The central part has a silver sunburst effect while the outer ring has a circular one. On this circular part we can see the polished applied  hour markers that have a black painted line or two (for 12, 3 6 and 9). It is marked in black writing: “Citizen College Alarm” at 12 and “parawater 17” at 6. The 4  polished hands are for showing the time and the shorter one, with a triangular tip is for the alarm. The hour hand (as well as the minute one) has a a central longitudinal black line, to match the hour markers.

The case is made in stainless steel, with 38 mm diameter, the lugs are elegant and the two unsigned crowns are easy to operate and still very well suited to compliment the elegant design. The bracelet and the clasp is made in stainless steel too.

citizen college alarm vintage

The movement is the Citizen calibre hand winding 9812 (no date), 17 Jewels, 18000 bph. The crowns are one for the time and the one for the alarm. The crown at 2 o’clock in first position is winding the alarm and the alarm is deactivated. If you pull it in the second position you can set the alarm (counterclockwise) and the alarm is activated. Pressing it while the alarm is ringing will stop it. The crown at 4 will wind the watch and pulling it out will set the time. The alarm will ring for 13-16 seconds. The movement has a power reserve of about 40-45 hours and it runs great if winding it once a day. It is Parashock.

Citizen Parawater – THE Parawater


After presenting the first watch manufactured by Citizen, the beautiful pocket one (read about it HERE), it is time for another milestone in watchmaking. This time, the first Japanese waterproof watch, THE Parawater! This makes it the grand, grand father of all the Citizen divers we all love so much!  Please note that this was not intended for diving, but it was up to the task for swimming!

In 1959 the company produced the first Japanese water-resistant wrist watch. This was the “Citizen Parawater”. It was powered by the Citizen Cal. 920(2B). It was produced with  19, 21 and 23 jewels. Soon after, the Parawater completed two trans-Pacific tests and one in the Sea of Japan. The result, needless to say, was positive. As time passed Citizen was growing as a company and exported more and more watches, so (unfortunately IMHO) the term “Para Water” was changed to the universally recognized (an boring)  “Water resistant” somewhere around 1970-1973.

Back to this particular one! The line chosen to be modified so that it will become water protected was a success already, the Deluxe. Citizen changed the design of the case, added rubber seals and greatly modified the tube and crown assembly. By doing that and after a lot of research they were able to stand by their product in public demonstrations.

Citizen Parawater Deluxe

After intensive search I managed to find this particular watch, in an non working state, the bracelet and the clasp was destroyed beyond restoration and the crystal was badly scratched, but what an awesome find! I had to take the plunge! (pun intended 🙂 ) This is how I got the pictures from the seller in Greece:

Citizen Parawater

Now, after a long time deciding how invasive the restoration should be I went with a bracelet swap with a similar design from the same time frame by Citizen, a light crystal polish and I got the movement running again.  This is the end result:

Citizen Parawater Deluxe

Interesting facts: The black dial has lume dots and the hands are also with luminous material, making it very rare (the only one I saw) and very beautiful. Another detail is the fact that the entire dial in printed and there is no applied logo.

The caseback has the inscription: “All stainless steel”, “Antimagnetic”, “Parawater”, “STAR”, “Citizen Deluxe” and the serial no. By the way the watch is made in 1959, making it one of the very first pieces.

Beautiful lug holes for easy bracelet replacement.

Don’t forget to magnify the last picture for more details!

Conclusion: I am so happy to introduce to you this wonderful piece of history and I hope you like it as much as I do! The watch found a new home with Daniel in Germany and for sure it is a great home! Enjoy it Daniel!

Later edit (2015): 

I here present to you my keeper Para Water, that I found this year in Hong Kong (thanks Anthony! 🙂 ) Excellent condition, fully working 100% original, made in 1961.

Vintage Citizen Divers 150m: 68-5372 , 62-6198, 52-0110


It is my pleasure to introduce to you my three vintage Citizen 150m divers: 68-5372 , 62-6198, 52-0110.

Even though they might look similar at the very first sight, they are different models.

vintage citizen divers 150m 4-740131Y , 4-600851Y , 4-820789Y

They are all in excellent condition, the first two are actually NOS, the third one is not, but really well kept. The first one is made in 1971, the second in 1974 and the third in 1978. Read about how to date a Citizen watch here: https://vintagecitizenwatches.com/2014/02/23/dating-a-vintage-citizen-watch/

Lets start with the similarities: 

All three are divers, rated to a respectable depth of 150m water pressure. They share the same case (4-740131Y , 4-600851Y , 4-820789Y ), with the same screw-in large crown. The bezel is bidirectional friction type. The sides of the cases are polished and the frontal surfaces are brushed in a similar manner. They are 40mm wide with 20mm steel bracelets at the lugs. Thew share the same mineral crystal, concave on the inside, with a flat surface, that magnifies the beautiful black dials. The movements are automatics with 21 jewels. All three display the date at 3 o’clock and have a central sweeping hand with a luminous dot. The hour indexes are applied rectangles, large, and filled with luminous material. The hands are similar in shape (Mercedes type hour hand and spade minute hand).  The three bracelets feature a diver extension link beneath the clasp. So, they are very much alike, but, let’t take a closer look!

vintage citizen divers 150m 68-5372 , 62-6198, 52-0110

The main difference is a small detail that I like a lot: The first one (made in 1971: 68-5372) is marked “parawater”. read more about parawater here: https://vintagecitizenwatches.com/2013/12/26/citizen-parawater-citizen-parashock/. All the other differences emerge, the way I see things, from this small detail (the date of manufacturing). The era of “parawater” was different. The first watch is the only one with a solid bracelet links, the others have folded links. The date window is better placed on the dial due to a different movement size on the ’71 watch. The hour hand and the minute hand are longer. The dot at the end of the second hand in similar to the first two models and I like this a lot. The bezels have different thickness, due to different crystal height.  The thinest being the first one, getting thicker and thicker, translating to an overall watch height difference. The way the crystal fits to the case is very complicated at early models, with steel rings, rubber seals, and a lot of parts. The third one has the crystal fit by pressure ring plastic gasket. The way I see things Citizen tried to simplify production and make it mode profitable, but I like it complicated. Looking at the bezel inserts, the last one has markers on every minute. The middle one features an applied Citizen logo on the dial made from individual letters. The 1978 watch has a black digit date wheel. By contrast the other two have red digits. As a final touch, the printing on the dial is unique to every one of the three.

Citizen vintage diver 150m

The casebacks are similar but with different markings. Removing the caseback we have the chance to see the movements. Three distinct movement, automatics, with 21 jewels. The most striking feature is the fact that the first watch movement is filling nicely the case, being a suited size (this is the reason for the date position on the dial). The later two have smaller movements. At least the middle one has a steel ring around it to fill the useless space. The latest one has a cheaper plastic ring. All three movements have quick date setting, and offer hand winding ability.

 As a conclusion, I want to say that even though I admire the first one and really appreciate the second one, the third (the only one that is not NOS) is the one I love the most. Nevertheless, I will not disclose the reason why. 🙂 Having one vintage Citizen diver 150m is a joy, having three is a bless.

UPDATE – the second hand I have seen to be either lollipop style with the ball at the end of it or not. For any of these models. I have yet to find catalogue pictures to be 100% sure about it.
