Citizen Seven Star Deluxe “Monthly” model ACSS-52704-Y


This is a nice full calendar Citizen, powered by a simple movement. Even though it looks like the month display is a complex feature, it is only a simple and clever internal bezel.  Due to this particularity (month display) it was named “Monthly” but another similar model is called “Moon – Dater”.  The reason for a this (one model with two names) is the fact that the “Moon -Dater” might have been designated for export.

The case is, as most of the times, made is stainless steel, with mirror polished flat sides and deep sunburst frontal surface. It has a cushion style shape with integrated lugs. The bezel holding the flat mineral crystal is polished and so is the stainless steel caseback. My watch is the black face one, while the credit for the pictures of the white one goes to an internet seller. Both of them are in perfect condition and the different surfaces can be easily admired mostly because of it’s generous proportions, being rather large. It has two crowns, one at 3 o’clock connected to the mechanism and one at 2 o’clock for easily setting the month. It is marked “Para water” (it is made in 1969, prior to the unfortunate term change in 1973 to international “water resistant”)

The dial is dark deep black, without reflections. The white one is as in the pictures. I didn’t have the chance to hold it and take a closer look. The hour markers are applied and polished. The “7” logo and the “Citizen” logo are applied in a similar manner. In the same way the hands and the day-date window frame are also polished. There is a second part of the dial, a raised internal minute disk that features the month window. All the disks (day, date , month) are white with black lettering (sundays are red). For the white dialed one the day is positioned at 9. There is also a version with a pink month disk (the Moon Dater?) I like the crosshair detail and the white lettering resembling white chalk writing on a blackboard on the black one.

The movement is the automatic Citizen calibre 5270, with 21 jewels beating at 18,000 beat per hour, with quickset date.  Some models have a 23 jewels movement. It is a reliable movement used in a variety of models displaying day and date. It offers hand winding possibility too. 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 operating crown for the movement is the one at 3. Even though it seams that the month display is operated by the movement, it does not. In fact it is an internal bezel that should be adjusted by the crown at 2 o’clock.

The bracelet for the black one (nor sure if it is the proper one for the model)  is tapering and closing with a signed clasp. The interesting part of the signature is the fact that is longitudinally placed along the clasp. Not too much to say about it, only a brushed bracelet that in my opinion suits the watch very well.The white one is on a mesh bracelet (not sure if original for the model).

All things considered, this is a simple, interesting watch, with a clever way of displaying the month. So, here we have a full calendar vintage Citizen.

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.

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.
