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.
The 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 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”.
Here is a video of another Citizen alarm with the same movement and this is how it sounds:
And this is another awesome his and hers real diving Citizen pair:
