Citizen auto Dater UNI – ADUS31201-T


It may not be a real diver but what a gorgeous watch it is! It was made in 1964, just 5 years after the introduction of the first Japanese water resistant watch, the Parawater, and about one year prior to the first real diving watch made by Citizen.

Let me introduce to you the Citizen auto Dater UNI reference ADUS31201-T

citizen autodater uni

The main feature of the watch is the fact that it is a twin crown, similar in appearance with a compressor. The upper crown, located at 2 o’clock, operates the inner bidirectional rotating bezel. By contrast, the lower crown located at 4 o’clock winds the movement and sets the time. The case is made entirely in polished stainless steel and measures about 38mm. The Tropic strap is 18mm at the lugs end and is secured in place by pins that can be easily removed due to the holes in the lugs (a feature that I like a lot in vintage watches). Hopefully one day I will find one on original bracelet. Will see.

The domed acrylic crystal protects the beautiful face. The dial is silver, having a sunburst effect. The doubled hour markers are polished and applied. The black elegant lettering are printed and so is the “40M” blue para water feature. The dauphine hands are polished and the hour and minute one have a central luminous part. The inner black rotating bezel has white printing and luminous material markers. On the dial itself the hours are marked with luminous dots too; all except the one at 3 where the date is. The date window has no frame but instead a beveled edge. The dates are printed in black on a white date wheel. I just love the way it looks! It is one of those beautiful watches, elegant and easy to wear.

The snap in case back is engraved “Para water,  Star, SS, Citizen auto Dater, UNI, ADUS31201-T” and the serial no. Strangely Citizen decided to mark them with the production date and so did they do it on older ones but not on their first divers. 😦 I wish I could say for sure when the first real diver made by Citizen was manufactured. Under the case back we have the automatic (hand winding also possible) Citizen 19 jewels movement, cal 2400. In the early till mid 1960’s Citizen used its own circular geared rotor (Jet rotor movements) in its automatic watches.  In 1963 they began replacing the Jet rotor with the more common oscillating weight, which, some say it was cheaper to manufacture and more easily to service than the Jet rotor. The first model to use the swinging weight was known as the “Uniauto” (cal 1200) and came in several versions, all with a special logo on the dial and in 17 or 19 jeweled versions. This watch, presented here, has the logo on the inner bezel at 12. It works at 18,000bph. The date changes by advancing the hour hand past midnight. The seconds hand do not hack.

Still I have to find out why is it called “UNI”?

UPDATE 2019 JUNE (5 years later)

I sold my UNI, the one in the picture above, a while ago and since then I was looking for another one, and as you already know me, I am always trying to get the best condition, NOS and mint if possible. Well… with UNI this was not an easy search. It took me a few good years, but I finally nailed it yesterday with Eric’s help! (Happy birthday my friend!) Here it is, my new UNI: (the picture credit goes to the seller, I am still waiting for my beautiful watch to get in my hands, really soon I hope) As you can see it is NOS, on a bracelet and comes with the original box! I am really happy about it!

How I wish Citizen will go vintage style again! Who knows, maybe one day…

And one more pic:

UPDATE 2021 Oct:

I was following an auction of a rare variant, black dial one, and it sold at a high price. It was to be expected because it is really rare and rare usually means money. I don’t like it as much as the variant I have and it was not NOS so I didn’t bid. But… what an awesome piece!

Citizen Super Ace 23 Jewels 40m


Well, apart from what is written on the dial there is not much info I have about this watch. It is part of the larger Ace family but, of course, it is Super. 🙂 The Super Ace. I date this one around 1966 – 1968 though I have no definitive answer regarding the manufacture date.

citizen super ace

First of all I notice the striking aspect of the watch, very modern, and gorgeous on the wist at 38mm diameter. Perfect size, no date, very balanced dial. The entire stainless steel case is polished. The mineral crystal is slightly domed and perfect, with very low unwanted reflections. The dial is a work of art: clean, harmonious, with the applied eagle medallion at 12 and well designed hour markers. The hands are a masterpiece. They have a beautiful shape, made in stainless steel, and are faceted, brushed (on the top part) and beveled, with polished sides and angles. The seconds hand is entirely polished. They remind me of the way Seiko finishes their Grand Seiko, and that is something for such an old watch! The finish of the dial has longitudinal brushed appearance and looks varnished. The elegant printing on the dial is black and it has no luminous material, nor do the hands. This must be one of the best faces Citizen has made!

citizen super ace

The caseback is engraved: SACS51301-D, Water Proof, Stainless Steel, and in the middle the profile of a man wearing a helmet (it he a diver, an astronaut or a medieval cavaler… I don’t know and I still have to find out). Either way, this is a rare out of the ordinary caseback. The winding crown is made in stainless steel too and marked CTZ.

The movement is gold plated, manual winding, non hacking seconds, specially adjusted one. It has 23 jewels and is marked Citizen Super Ace. It is the Citizen calibre  SACS 9240? and beats at 18,000bph.

Here it how the papers look like:

citizen-super-ace

Questions to be answered:

  1. when was it made?
  2. what more info are available on the Eagle logo on the dial?
  3. what is the engraving on the back?

All things considered I have to declare this, not the best but definitely one of the best looking vintage Citizen watches. Also wearing it is a joy.

Citizen movement table from 1931 to 1978


My friend, Stephen , did an extraordinary work putting together all the info that summarises the development of Citizen movements since the very first day of the company’s existence. This is an ongoing project that I am sure it would be a great source of useful information for all of us. All the data is introduced in chronological order.

Here it is: LINK HERE

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.

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 Leopard 28800 4-720032TA


It is always nice to visit new places and when one of these places is Hong Kong there is no way that you should leave empty handed (pun intended). So, on a watch hunt I went. I talked to my friends from the city about the best places to find vintage watches around there and started roaming the streets. Little did I know that fate was going to prove that my hotel was perfectly positioned so, in the end, one thing leading to another, I found my dream watch only because I bought the one in this article (that is a another story to be told after I get THE watch in my possession). Back to the story, here is what I found:

citizen leopard 28800The interesting feature of this watch is the little word that describes, well… a big cat: the Leopard. The Leopard range is special due to the high beat movements. Some of them are 28,800 and some are 36,000 bph. This particular range of watches was introduced in about 1969 and only lasted for a few years, enough time for Citizen to make about 15-20 variations of Leopard movements based on 72xx and 77xx calibers. (as a side note: way too many variations and not enough DNA unfortunately) Also a great number of cases and designs were made so I am sure you can find a Leopard perfect for your taste. 🙂

This particular watch has a stainless steel polished cushion shaped case, a simple, smooth, polished bezel and a stainless steel case back. It was made in April 1974 (funny thing I have noticed – a lot of the Citizen watches I have/had were made in April). The quartz revolutions was about to change the watch world. Just think about the fact that Citizen today is the largest watch company based mostly on quartz, the very same quartz that almost killed what we love so much, the vintage mechanical Citizen watches. 😦 The dial is silver, simple, with a beautiful sunburst effect. The applied hour markers have a black line while the 12 o’clock one has two black lines. These black details work very well with the black hour and minute hands. The sweeping second hand is polished. The Citizen logo is also applied while the rest of the text is printed in black: “automatic, 28800, Leopard, 26 jewels”. One can easily understand from reading the dial that the movement inside is automatic with 26 jewels. On top of that it can also be winded by hand. The date is quick set while the day changes by advancing the hands past midnight. It is a hacking movement (the second hands stops when setting the time). The picture below is a part of the scans made by me of Citizen vintage catalogues.

Citizen leopard calibre 7200 36000

As a conclusion: beautiful watch and an interesting reminder of how fate works!

Vintage Citizen Newmaster – Jet Autodater


What can I say about this one? Well… I love this movement!

Citizen Newmaster autodater

The case is the usual classic style, made in stainless steel, with a screw in caseback. It is 35mm in diameter and it is entirely polished except for the sides that are brushed. The winding crown is made in stainless steel (just as the entire case is) and it is signed CTZ. The polished bezel holds in place a domed acrylic crystal.

The dial is silver, simple, with a sunburst effect. It has black writing: “Citizen 21 jewels”, “Newmaster automatic waterproof”. The applied hour markers are polished and have multiple surfaces that reflect the light no matter the angle from where you look at them. The hour date (black numbers on a white disk) has a applied frame too. The hands are polished too (without luminous material) and have a classic shape.

Citizen newmaster autodater

The movement is the main feature of this watch due to the ring rotor that I like a lot. It is a 21 jewels movement, beating at 18,000 bph. It has a power reserve at about 45hours. The date changes only by advancing the hands. The movement, as stated , is an automatic but can be manually winded too.  I came to the conclusion that the rotating ring has 4 or 6 screws but the 4 screws one seems to be a more rare type. The thing I like the most it the beautiful sound that the rotor is making when rotating, smooth, loud, mechanic.

The strap in this case is a aftermarket shinny lizard skin one. I think it goes very well with the watch.

As a conclusion, I think anyone would love to experiment at least once the sight and the sound on a ring rotor vintage Citizen movement. I really am!

Citizen Chrono Master Autodate 33Jewels


Chrono Master – this says it all.

Chrono Master was, and still is,  the most recognizable high grade line of Citizen,  a real competitor for Grand Seiko and Swiss made watches.

Vintage Citizen Chronomaster

I love the look of this watch, elegant, yet casual, perfect for a suit as well for any daily attire.

The case is made in stainless steel, having what I consider to be a perfect design. The lugs are beautifully designed and every detail shows the great care placed into drawing each line, each angle, each corner. The entire case is polished. The case back has a gold inlay medallion with an engraved eagle.  The winding crown is the right size and shape for the watch, signed “C”. The mineral crystal is flat, sitting higher than the bezel. It’s angled edge makes the dial pop and bends the light is mysterious ways.

The dial is silver, with an sunburst effect. Very clean and organized. The hour markers, the date frame, the Citizen logo and the eagle logo are polished and applied with a lot of care. The details are impressive. There is not much writing on the dial: “Chrono Master”, “Autodate” an “33 Jewels” – this all the information needed to see how this is not an ordinary Citizen. The hands are polished too matching the hour markers, having a longitudinal middle black line.

Citizen Chrono Master autodate 33 jewels

Citizen 33 jewels cal 5440

The movement is the Citizen calibre automatic 5440 with 33 jewels, beating at 18,000 bph. It can be also with a day (5450) or only date. The number of 33 jewels is high enough but not the highest. Some of these movements are also Chronometers, adjusted to a higher precision. This was possible by the adjuster positioned on the balance. The automatic movement can be winded by hand also. It is a quick set date, and it hack for better time setting. It is a beautifully made movement complimenting the overall design in a fortunate way. The movement print presented here is a part of Stephen’s scans of a Citizen catalogue. His work can be read here.

The strap, in this case, is an aftermarket black snake with a sharp stainless steel custom made buckle. I think this suits the watch very well. I wish I could find an original Citizen buckle of the era but I don’t have high hopes on that.

Conclusion: Beautiful design, wonderful quality, great watch! Every Citizen collection needs a Chrono Master!

Update 2017 September: Here it is a rare blue dial version. Notice the applied logo on 6 and the hands shape. (pictures from the on line seller)

Citizen Soccer Custom (Yacht Custom & Rally Custom)


In their quest of diversifying their watch lines Citizen introduced in about 1970 a range of custom made watches. These were meant to target the sport area, specifically Rally, Soccer and Yachting. They were based on the Seven Star models and were modified so that they would fit into these three types.

The Soccercustom is designed to be a useful tool in timing the 45 minutes soccer game. Just as the other models of the range, in order to do this the watch has an inner rotating bezel.

Screen Shot 2014-04-26 at 16.11.43

The case of the watch is made in stainless steel, polished with brushed sides. It is cushion shaped and is 4o mm wide.  The mineral crystal is large, with a flat surface. There are two crowns, a lager one at 3 o’clock for winding the watch and adjusting the time and a smaller one (integrated in the case) at 4 that rotates the inner bezel. Both of them are signed “CTZ”.

The dial is black, with an outer silver ring that has the minutes scale. The rotating bezel in marked from 0 to 45 minutes. On 3 o clock there is the day-date window.  It is marked Para100mwater 21 jewels asa well as the Citizen (producer), Seven star (line) Soccercustom (model).

The movement is the automatic (also hand winds) Citizen calibre 5270, 21 jewels, non hacking. The Rally Custom and the Yacht Custom are powered by 25 jewel movements, 5290. The automatic movement runs at 18,000 beats per hour. The date can be changed by the operating crown but the day changes only by passing the midnight with the hour hand.

The bracelet is simple, folded links, made is stainless steel too, with the usual signed Citizen clasp.

Conclusion: A nice professional watch, along with the Rallycustom and the Yachtcusom, a rare piece that has its place in any  vintage Citizen collection.
