Citizen Seven Star Para100mWater APSS2812-Y


The watch I introduce to you today is a variation of the Vintage Citizen compressor style diver 4-520343 Y, I wrote about HERE.

I called it a compressor style case because it is not a real compressor one but it only has the look of one. It has two crowns and an internal bidirectional rotating bezel that is operated by the crown at 2 o’clock.  Because I have already reviewed the sister model in the article about 4-520343Y HERE, I will only post the pictures and point out the differences.

So, this is the blue dial one, as clearly seen in the picture, and the dial in marked Seven Star. The case, movement, hands, crowns and straps are shared between the two models. The dial on this one is marked parawater and has the Seven Star logo “7” applied. The caseback is also different with different engraving.

For this particular watch I think the Tropic strap is a good match and really nice to wear.

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.

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.

Citizen compressor diver – Seven Star 4-520017Y


Let me introduce to you a beautiful, NOS, vintage compressor style diver that has just the right amount of pure class.

A compressor case is defined by the fact that the rotating bezel is inside the case, under the crystal and it is turned by one of the crowns, rather than directly by hand. Gary, a reader, provided a piece of information about Compressor cases that I would love to share with you:

“These are beautful watches and I enjoyed reading about them but I must correct your assumption that they are compressor watches. Its a common misconception that if a watch has two crowns and an internal bezel, it must be a supercompressor but infact Compressor and Super Compressor watches are defines by the company which made the cases and held a patent for their design. These cases were made by the specialist manufacturer Ervin Piquerez S.A. of Switzerland. No Japanese manufacturer used EPSA Compressor cases. Information about Compressor cases is not hard to find. The link below shows the three types of Compressor case, including the Super Compressor from which your Citizen watches are inspired. True Super Compressors are typically identified by a crossed hatched design on the crowns, a diver helmet logo on the case back or inside the case back, but always, they have the brevet (patent) number on or inside the case back. http://wornandwound.com/2014/03/24/guide-super-compressors/”

NOS means New Old Stock – a watch that was not worn and it is in excelent condition after all this time (45 years old).

Just like the other compressor diver I have presented here : https://vintagecitizenwatches.com/2014/01/18/vintage-citizen-compressor-diver-4-520343-y/, this one is also made in 1969. By contrast, this one has a more classy, elegant appearance.

The case is large, made in polished stainless steel, with a brushed frontal surface. Looking at it from the side, the case seams slender, thick in the middle, and arching down all the way to the end of the integrated lugs. The mineral crystal is slightly domed in order to be better integrated in the overall design. The crystal is secured by a thin, polished, elegant bezel. The sides and the frontal surface are well delimitated by a carefully made polished chamfer. The twin crowns are not signed. One of then, the upper one, turns the bidirectional internal bezel and the other one is connected to the movement. The case-back displays the usual information – material, date of manufacture, model, movement, and parawater. Read about parawater here: https://vintagecitizenwatches.com/2013/12/26/citizen-parawater-citizen-parashock/

The dial is dark-deep black,  very simple but not simplistic at all. Under magnification one can see that a lot of attention was placed into details. The writing is white, also on the black date and the black day wheels. The date is on 3 o clock inside a polished frame and the day is at 9 inside an oval, carefully made window. The only tint of color is the lettering for Sunday.  The inner rotating bezel is also black with white writing. The hour markers are applied with luminous material in the center. The hands are also polished, faceted with luminous material as well.

The movement is the usual automatic Citizen calibre 5270, with 21 jewels. The calibre number is engraved, as usual, under the balance wheel.  It is winded by a black rotor that compliments the dial on the other side in a fortunate manner.  It is a common movement used in a variety of models, not only divers making it rather easy to repair with available parts. It is reliable and offers hand winding possibility. The date changes in the second position of the winding crown (first position for winding, third for time setting) but the day changes only by passing midnight with the hands. The corespondent crown for the movement is the one at 4 o ‘clock.

The bracelet is nothing less than a piece of art. I think this is my favorite Citizen design. It is made in solid steel, three thin polished connectors and  brushed large links. It doesn’t get better than this! It has a pleasant tactile feel and a nice weight. One more thing that can not be described into words is the sound of the links touching each other… pure music. The clasp is the usual type, signed Citizen.

Al things considered, this is the best diver for a gentleman, ready to be worn at the beach or with a suit during a corporate meeting. Decent water resistance (nor really made for submerging, but good enough for daily jobs) and understated elegance placed together for one of the best Vintage Citizen All-rounder.
