Vintage Citizen Diamond Flake – World’s thinnest watch


What is so special about this one? 

Is it made with diamonds? No. Than what?

Citizen Diamond Flake

The case is made in fact of stainless steel and is really elegant. This is how a suit wrist watch should be like. Simple, 3 hands, white dial, manual wind. Back to the case, we can see that it is really, really thin. In fact it is called Diamond Flake because at the time it was the thinest watch with 3 hands (about 7 mm thickness and 38mm diameter, with a really nice wrist presence and appears larger). In August 1962 it was the world’s thinnest 3 hands watch developed. The acrylic crystal is slightly domed making it thicker. The winding crown is small but easy to operate, not signed. On the case back it is marked with the model, serial no. (dating this watch February ’63, that means it is one of the early production).

The dial is very simple, silver, with a sunburst effect. The hour markers are applied and both the hour markers and the hands are polished without luminous material. It is marked: ” Citizen Diamond Flake” and “Parashock 25 jewels”. At 12 o clock there is the Diamond Flake logo.

I love the way that it is gold plated.  At the time the race for slimmer watches was on and having a thin movement was a must. Well, this one was the champion. It is only 2.7mm, 0.2mm thinner than the competitor Seiko Gold Feather. The calibre 0700 has 25 Jewels (calibre 0701 had 31 jewels). Later on a date was added to the 25 jewels movement and this how Citizen calibre 2700 was born.

The strap is a vintage Citizen brown leather one, with a stainless steel buckle. I think it compliments the watch nicely and adds something to the overall appeal of the watch.

The watch can also be found (not easy, but it can de found – I did it) in a pocket watch form. Here it is, with original chain. Same beautiful movement in a large case, with an acrylic crystal.

Conclusion – some might say that this is the ultimate elegant watch, some might say it the perfect suit one, but no one argues the fact that it has it’s well defined place in history as a champion of it’s own time.

Update: I also found (pictures from the seller) a black dialed one (still not sure if original or repainted dial) in a gold plated case. The dial on this one is marked Parawater.

Update 2017: We can’t really argue on the fact that this model is one of the best dress watches, isn’t it? Having it made of solid White Gold I guess it makes it even better. Is it perfect this way? I don’t know but it is a real beauty. Well… here it is so let me introduce to you, the pure awesome, the best of the best, my keeper,  THE WG DIAMOND FLAKE! At the time the price was 40,000 JPY, and that was expensive!

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 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)
And the bracelet version:

Vintage Citizen Diver – Seven Star 4-526970Y


This is not the usual diver, but it has the lovely look of one. In fact this is one of the first “divers” made by Citizen, the precursor of the famous Citizen real diving watches.

It is the Parawater model but it has no specific depth rating. The production date of this particular watch is February 1970.

The case is made in stainless steel, thin, with a bidirectional friction type stainless steel rotating bezel. It measures 38mm wide. It has a domed acrylic crystal that gives a lovely look to the black, matte dial. The crown is marked “C” as most of the early Citizen watches did and it is not screw type.

The dial is simple, black, with luminous squares as hour markers. At three a clock it has the day-date window. Sundays , as usual, are written in red. The hands are common to Seven Star range at the era. The second hand has a luminous dot at the tip.

The movement is the the calibre 5204 with 21 jewels. It runs at 28,000 bph and it doesn’t hack. The date changes in the second position of the winding crown and the day changes by advancing the hands pass midnight.

The bracelet is made in stainless steel, but I doubt the fact that is original to the watch. It fits the watch really nice.  The clasp, is as usual, signed “Citizen”.

Conclusion – Beautiful piece of history, a precursor of the real Citizen diving watches, the “missing” link between THE Parawater watch and the real diving watches made by Citizen.
