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!

Citizen 150m 62-5370 & B52806


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.

citizen 62-5370 citizen B52806 (2)

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!

Complete Vintage Citizen 150m Divers


No Citizen collection can be considered a real collection until a 150m diver is included. This is the most recognizable diver line in vintage Citizen so sooner or later for sure one model will come up for sale, just in time for you to grab and never let go. In fact there are 7 different models that to the untrained eye look almost identical. One for every day of the week, I would say. Well.. now that you have one, you will soon feel the urge to get another one and another one, and then a better condition fist one, that you already have, and another one. Without even realizing, it soon becomes an obsession, to have them all, and to have them all in top condition! The hunt is on!

So, it is my pride and joy, my pleasure to introduce to you the entire 7 watches collection! 

vinatge citizen divers 150m

Let me tell you about them, in chronological order, starting from 1967 up to 1978:

  1.  Citizen Super Auto Dater, SADS 52801-Y was made in June 1967. It is my favorite. What is there not to like? It has a unibody case (the case back doesn’t come off), it has a top of the line 39 jewels Jet movement, calibre 1150, (read about Jet movements HERE) and it is marked Professional Parawater. The crown threads are on the outside of the crown tube. The case is shaped differently and it shows that a lot of effort was placed into designing and producing it. I just love the angles and the contrast between the brushed and the angled polished surfaces. Read about this model HERE. Is is on a Tropic strap. I didn’t see any on bracelet. I hardly saw any at all in fact. 🙂 Super rare!
  2. Citizen Crystal Date, AUDS 52802-Y OR-O was made in My 1968. Did you ever see a better case back? Maybe you think you did, but take a look at this one! I am sure you will love it! The hands are different then the rest because there is no “Mercedes” style hour hand. The mesh bracelet is awesome, the crown is as it is for the first model and starting with this model the top part of the case has now a circular brushed finish rather then a longitudinal one. The uni case was dropped and starting now the case back screws into place. Starting with this model the Jet movement was replaced with a centrally mounted swinging weight. This one has the most beautiful aged lume. Read about that HERE. The movement is the Citizen automatic calibre 5410.
  3. Citizen Diver OR-O B52806 or 62-5370 are the same model but the first one is the one to have, because of the beautiful engraved case back. The 62-5370 is made for domestic market and the B52806 for export. They have different case backs, different hands sets and dial codes even though they share some of these features sometimes. The second hand tip received a luminous ball for better visibility (The 62-5370 can be found with a simple second hand too) The only thing that is constantly different is the case back. The movement is Citizen cal 5470. I had to chose between these two and I decided in favor of the first one. You can’t beat that awesome diver engraved case back! It is marked water proof in a period when the term Parawater was about to… unfortunately disappear. Is was made in ’69-’70 but the exact period is impossible to determine because it has no serial no. The 62-5370 on the other hand, has one and the manufacturing date can easily be seen. Read about these two variants together HERE.
  4. Citizen 150m 68-5372, 4-740131-Y is made in May 1971. It is still marked “parawater”, for the last time in this line. Read about “parawater” HERE. Starting now the case is different again and the crown has the threads on the inside, not on the outside of the crown tube. It has a different shape too and it is made in stainless steel. The previous ones I think are only capped in SS. And this is when the case backs became… well… displaying a lot of information but… boring. It is powered by Citizen calibre 7470. vintage citizen 150m divers
  5. Citizen 150m 4-722410 Y is made in October 1973 and is the only one displaying the date as well as the day of the week. The movement is from the leopard family, calibre 7200. That is always nice to have. You can read about it HERE. The bezel insert got a thin crystal layer on top of the luminous dot making it more resistant to water and normal usage while giving it a special look with a black ring around it. The sweeping second hand is straight again. And, as I said before, no more “parawater”, time for internationally common used “water resistant”.
  6. Citizen 150m 62-6198, 4-600851 Y is made in June 1974 and got a luminous marker near the date window. Pay attention to the fake “aftermarket” bezel inserts that you can learn about HERE. The date can be printed in red and the rest is, more or less, the well known design we grew to love so much. The bracelet is the H style links. Read more about it HERE. The movement inside is the Citizen calibre 7000.
  7. Citizen 150m 52-0110 is one of the very first Citizen watches I had. It is in fact my birth year watch and my month also. 🙂 It is made in July 1978 and marks the end of an era, 1978, the last year for vintage Citizen watches. It is the the one that started this hunt a few years ago. It comes in various forms, even with an orange dial, maybe blue one? maybe an orange dial and blue bezel insert? (I think the “blue bezel inserts are in fact faded and originally black) Two dial variants 1977 and 1978 that you can read about HERE. You can also read more about this model HERE. The beating heart is the well known Citizen calibre 8210. 150m citizen vintage divers copy

And… the rest is history. 🙂 I hope you found you perfect 150m diver and if you didn’t, don’t give up, I promise you you will love it and the wait is worth it!

PS – who knows… one day I might find out there is another one and maybe another one… So far, these are all I am aware of. 🙂

Citizen “Leopard” 150m diver day-date 4-722710 Y


In fact it is not really a “Leopard” but it is equipped with the same movement that can be found mostly in the Leopard range. Also, the case style is the well known one used by Citizen in their 150m divers. What can I say, the perfect combination of style and functionality. This is the (October 1972) Citizen 150m day-date diver model 4-722710 Y.

citizen 150m day date leopard 7200 4-722710 y

The case, as stated before, is similar (not exactly the same though) with other 150m divers. Read about similar divers HERE. It has the same 40mm diameter, brushed top surface, polished sides, large unsigned screw in crown, screw in case back. The lug width is 20mm. There is also a bidirectional friction type bezel. Again, the bezel has a few variation among 150m divers. It is important to pay attention to this because a lot of these pieces come with aftermarket bezel inserts or wrong ones. I wrote an article about one particular fake & real inserts HERE. The crystal has a flat surface and it is concave on the inside. Of course, the water resistance is 150m.

The interesting feature of the watch is the automatic movement, Citizen cal 7210, 24 jewels. It works at 28,800 bph, 8 ticks per second, 4 Hz. It can be hand winded too as most of the Citizen movements do. Because the watch has this calibre, it displays the date as well as the day of the week. The dial is black, with raised hour markers, logo and day-date frame. The printing is white. On the bottom it is also printed the dial code 726257 Y and Japan. The hands are similar all across the range, with slight variations in size and shape. In this case the sweeping second hand is straight without the luminous dot as others have. I have seen a variation of this exact model with a black day and date wheel and that one has a second hand tip with a luminous ball.

The strap is a curved end Tropic rubber one that fits the watch nicely and gives it a lot of personality. Lovely watch to have and wear.

Citizen Super Auto Dater 39J 150m Professional


That is a long title! In fact it is even longer, it is:

“Citizen Super Auto Dater 39J Para150mWater Professional SADS52801-Y”

This must stand for something and for sure it means business! 🙂 Citizen Super Auto Dater

This one is one of the very best Citizen has ever made. I was lucky enough to find a mint, NOS example.  It has all the characteristics that a top quality iconic vintage diver should have. Even today after almost 50 years it stands out proud in the tough world of diving watches.

It has a unibody case (the case back doesn’t come of and the movement can be taken out only by removing the crystal)  made in SS, 40mm diameter, all polished except for the upper part of the beautifully shaped lugs. The fact that the case is monocoque is obvious when reading the engraving on the back where a small “X” inside a circle can be found. This is the sign that Citizen used for a unibody cases. The crystal is tightened in place by a steel pressure ring and there are two rubber seals that protect it from water intrusion. One ring in under the crystal and one on the side of the crystal. The crown too has it’s own rubber O ring making the watch water resistant up to 150m. Citizen used the term Para Water. (I love these words) So the watch is Para150mWater, making it the first of the iconic line of 150m divers Citizen made with the same overall look and function. No Citizen lover should miss having at least one 150m vintage diver, no matter the model.  Back to the crown (unsigned and polished), one interesting feature is the fact that the threads are not on the tube connected to the case but on the crown itself. So the crown indeed screws INTO the case and not ON the case like most of the screw-in crowns do.

The thick crystal,  flat on the surface and concave on the dial side gives beautiful reflections and makes the polished hour markers really pop. In fact the entire face of the watch is pure gorgeous! The elegant writing, the polished hands and hour markers, the green luminous material (still glowing powerfully today), the date window… awesome! How beautiful is it to read: “Citizen Super Auto Dater 39J 150m Professional” and then, the 3 stars, the sign that Citizen used for superior watches at the time. “Professional” – nice! 🙂

The bezel is bidirectional friction type with a simple insert with a luminous dot inside a triangle.

The strap in this case is a Tropic curved ends one, 19mm wide at the lugs part that I think compliments the overall appearance of the watch a lot. It is a diver, Citizen used Tropic straps and this combination is gorgeous.

Citizen Auto Dater 39J 150m

Inside the watch the magic continues! The 1150 citizen calibre with 39 jewels is, if not one of the best, for sure one of the most beautiful movements Citizen has. The Super Jet movement was introduced in 1963, my watch is made in 1967, June. It beats at the usual 18,000 bph and it is automatic with hand winding feature also. It has a date that can be adjusted by passing the hour hand over midnight. It is not a hacking seconds. The beautiful part is the circular geared rotor. This is what Citizen called Jet movements. Some say that Citizen replaced this type by the centrally mounted oscillating weight because it was more economical to produce and service even though not as qualitative. I would have expected to see a six screws  rotor when opening the watch but I was equally pleased to find a rotor type that had four and is engraved “Citizen”only, without the usual “super jet”. The entire movement is gold plated.

Here it is how the papers should look like:

citizen-super-auto-dater-39j

As a conclusion all I can say is that finding one of these is not an easy task but when completed the joy is huge and for sure this is a watch that once in your collection you will never ever sell.

Undersea Treasure – Citizen 150m 52-0110


The emotional connection with our watches is in fact the main force that drives us into collecting them. A 1969 great Moon landing story made the Omega Speedmaster the icon that it is today. Same goes with “Paul Newman” Rolex Daytona, Heuer Monaco and many others. Patek takes the emotional connection to an art form level. Well, now we have a great Citizen story too!

Starting from this post and then with the contribution made on the Vintage Citizen Watches group page on Facebook  by Renato I am here to introduce to you this great story of the Citizen Undersea Treasure. Our hero is the vintage Citizen 150m diving watch model 52-0110. I also contacted the newspaper and Stephanie was happy to provide me all the information they had so far regarding this. Unfortunately they were more into the interesting situation and not into watches so a lot of details I had to figure out myself.

You can learn more details about this model (Citizen 150m 52-0110) in HERE.

Neil Blakers of Cromer found this awesome watch while “strolling along the beach on Saturday afternoon”  on Long Reef Beach in Australia.  “I realized it was a watch but the face and body were covered in barnacles. It looked as though it had once been growing on a rock or at the bottom of the ocean and been thrown up by a heavy surf” he said. He treated the found object with lemon and grapefruit juice only to clearly notice that the watch was still ticking. In the pictures below the seconds hand is in a different position so the watch is for sure still alive. That was great news indeed!  Neil understood the importance of his find and took the watch to Citizen Watches Australia at Brookvale who forwarded it to the Tokyo Head Office where they determined at the Product Quality Section of their Tanashi Factory that the watch was made in 1977. Based on my knowledge about vintage Citizen divers it is safe to declare that the exact model number is 52-0110, type 1 dial variant. Read here about this dial.  The watch was found in 1983 but it is unclear for how long it stayed submerged into the salty waters of the Pacific Ocean. Some researchers think that based on the way it looks we can assume it was “diving” for maybe 2-3 years.

In the picture we can see that the watch is still attached to the red nato strap so I will wear mine (same model, same year) like that for the next days. 🙂

citizen-lost-in-the-ocean-australia-52-0110-diver-red-nato

The nato strap and the fact it got lost there make me believe that a surfer lost it while riding a huge wave. It is a nice imagine to picture even though there is no clear evidence this is the true. In the end the mystery is the salt and pepper that makes a good story.  The water resistance of this model is 150m, it has a thick mineral crystal that is well fitted into the case and a screw in large crown. The caseback also screws in so in my mind there is no doubt that these are real tool watches. My 52-0110 diver was pressure tested by my watchmaker and to my excitement passed with flying colors. The movement inside is the automatic Citizen calibre 8210A with 21 jewels.

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.

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?!

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.

1978       52-0110        4-820789Y      8210A

 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.

Citizen automatic diver 51-2273


Another vintage diver is the model 51-2273.

This one is  more recent than the previously featured watches here.

citizen diver 51-2273One of the main feature about this one, compared with the others, is the unidirectional rotating bezel. Also, the “Mercedes” hands are gone and are replaced with a different style.

The case is made in stainless steel,  with a brushed (circular) front surface and polished sides. The case back screws in and it is polished too. This case features crown guards for protecting the crown, a nice diving detail that enhances the “tool watch” appearance. Another diving feature in the screw in crown and the unidirectional bezel. This time the bezel has 60 solid clicks and rotates only counter clock wise. On 12 it has a triangle with a luminous dot. Every 10 minutes are marked with numbers and every minute by lines. The overall size is perfect, at 40 mm diameters without the crown and 20 mm between lugs.  The mineral crystal is flat.

The dial is mate black without any reflections. The hour markers are dots or lines, depending on the position. They are filed with luminous material. The hands are also luminous and they have a distinct shape, more geometrical, that I think enhance the overall look of the watch. On 12 there is the applied Citizen logo and “automatic”; on 6 there is the writing: “21 jewels – water resistant – 150 M ” On 3 there is the day-date window, in a single frame. The day is bilingual with red “Sunday” while rest are black.

citizen diver 51-2273The movement is the well known automatic Citizen calibre 8200A (Miyota). It has 21 jewels and offers a hand winding capability. First position of the crown wind the watch, the second will change the day and the date (in different directions) and the third will set the time. It beats at 21,600 bph and has a power reserve of 43 hours. The rotor will wind the watch in one direction only. Nothing fancy about this, just a reliable, simple movement that is doing it’s job as it should.

The strap on this watch is a rubber one with a stainless steel clasp. Rubber fits it very well and next to the nato straps it is the best option for this model.  The width at the lugs is 20mm so plenty of strap options are available at this size.
