Citizen Crystal Seven para100mwater diver


Exactly one year ago I wrote about a fabulous watch, the Dandy Seven diver (read about it HEREand here we are today talking about it’s brother, the Crystal Seven diver. They were made in the same period, they share the same line (Seven), the same movement, and the same style, but each stands proud as powerful individual watch.

It is a decent sized watch, with a modern look and a strong vintage feel; maybe it is the shape of the case, maybe the colors, maybe the entire watch. By the way, it is made entirely of stainless steel. The SS bracelet I doubt it is the original one but it suits the watch very well, with those blue highlights, that match the minute chapter ring color perfectly. The front part of the case is brushed while all the rest is polished.

It is a diver watch (para 100m water) and as any diver watch that respects itself it has a bezel. This one is an aluminum bidirectional friction type with a luminous dot on 12. The dial is beautiful, grey, with a sunburst effect. The hours are marked with luminous material. The hands had luminous parts too but on mine they must have fallen out and to this day it was not yet relumed. The second hand has a luminous ball too. The minute chapter ring is blue with white 5 minutes dots.

The movement inside is the Citizen automatic 5204 calibre, with 27 jewels. It can also be winded by hand. The winding crown is made of stainless steel and signed CTZ. It is not a screw-in type. Due to this movement, the watch displays both the day of the week as well as the date. The day changes by advancing the hands past midnight while the date changes normally in the second position of the crown. The movement doesn’t hack.

One thing that differentiates it from it’s brother (the Dandy Seven) is the mineral crystal (hence the Crystal Seven name). On the other hand, Dandy Seven it fitted with an acrylic one.

All things considered it is a beautiful, rare diver, vintage and somehow modern at the same time.

Citizen automatic diver 150m – 52-0110


Vintage divers – every time I hear this combination of words my heart races a little. 

I dream about that period in time when a watch was what it was supposed to be, a true tool watch, a real diving instrument, not a desk diver fashionable statement as it is most of the times today. Was it a good thing or a bad one, who am I to judge? But for sure I love a vintage diving tool watch such as this one I am talking today. Lucky me I have a NOS one, birth year and month 52-0110, and this is awesome. I love it!

The 150m Citizen is, in my opinion,  one of the best looking vintage diver ever! It has everything a real diver should have: decent water resistance (150m), screw in crown and easy to use, screw in caseback, a diver bezel, clear indexes, easy to read hands contrasting with the matte dial, a sweeping central second hand, thick glass, diver extension clasp and the most important: a reliable movement.  Wearing this watch makes me dream about the Ocean depths and underwater adventure. It looks good on original bracelet, on nato, on mesh bracelet, on rubber and even on a rugged leather strap. Beautiful watch!

The case is made of stainless steel, 40mm diameter, 13mm thick, brushed face and polished sides. It has thick lugs and it is rugged and powerful without being overwhelming. The perfect shape and size for a diver. The screw-in crown is easy to operate, and it is unsigned. The bezel is frictional type, bidirectional, easy to use but not so easy to mess with when underwater. Pay attention because most aftermarket bezels don’t have dots at every minutes. The lugs are 20mm apart accommodating most modern straps you throw at it. The mineral crystal looks like it is domed but in fact it is flat. The underside is actually concave bending the light in a mysterious way that makes me day dreaming. It sits at about the same height (or slightly higher) with the black bezel.

The dial is gorgeous. Plain, matte, deep black. There is no reflection. The reflection comes from the crystal and from the indexes and the hands. Not too much writing on the dial except the applied Citizen logo, automatic, 21 jewels, water resistant, 150m. At 3 we have the date window. Something about the date window – there are some variations here – with or without luminescent index at the side, in the same frame with the date, or in a separate frame. The luminescent material is glowing even more than 40 years later and has a superb green-yellow light to it.vintage citizen diver

The movement is the work horse 8210A, 21 jewels, automatic with hand winding capability. Not much to say about this, it is just a clean, easy to use and service, reliable movement. Nothing fancy, just a up to the job honest movement. It beats at 21.600 bph and has a quickset date. The first time this movement was used in this watch seems to be 1977. You can see the date of manufacture in the serial on the caseback. The first number is the year, the next two digits are for the month.

The bracelet is stainless steel, with “H” shaped links. Very comfortable. The clasp is also stainless steel, signed Citizen. It has a diver extension. The bracelet should be brushed. My NOS one came on the original Tropic strap with Citizen signed SS buckle. So… Tropic is original and bracelet is original too.

Update 2017 September: An orange dial one and a NOS 52-0110 with box  and booklet with pictures from the online seller:

Not sure if both boxes are correct? They might be because there are quite a variations of 52-0110 models so I expect it for the boxes to be a little different too. Who knows?

And here it is the booklet of the watch: Thank you Mikko and congrats on yours! Mikko’s booklet was in English and Spanish.

Conclusion: Beautiful, real diving watch, a time capsule that as soon as it is strapped on the wrist ticks away telling a story about sand, sun, and underwater adventures. A watch made for real men, a work horse that enjoys being wet. Give it at least a short shower every once in a while! 😉
