The Mystery of The First Ever Citizen Wristwatch


WWII was a time when some sort of a military use was mandatory for most of the items produced at the time. Watches were no exception and Citizen was also involved in making military watches. One of them might be the one presented here. Seiko (and Seikosha) was the most prolific manufactures for military watches but this particular watch might be proof of the possible link between these two Japanese watch giants. WWII citizen wristwatch pocket watchThe case is a in fact a transitional one, having a pocket watch body style inside an outer wrist watch case. It is chromed but both the casebacks are stainless steel. The case is small at 30mm diameter. Both of the parts have acrylic crystals. The outer case has lug holes. I think this could be an indicator that the watch had usual strap and not some type of nato as often seen on military watches (those have fixed lug bars). (read the comment below made by Keigo on nato straps) On the wristwatch part, the caseback reads: “Patent. no. 274740, Dust-Proof, Stainless steel, Back, 1428” Later edit thanks to Stephen: “Citizen’s research institute was called Shokosha.” The dial is simple with subsidiary seconds dial, at 6 o’clock. The arabic hour numerals are applied and so are the minutes markers on the outside. The overall design of the dial is carefully planned, with concentric parts and overlapping disks. The hands are blue, and they seem to be heated blue rather than painted. Citizen patent no 274740 dust-proof  1428 The movement is another mystery, to me at least. It looks like a Seiko calibre but is signed Citizen. So, is it Citizen or Seiko?  In the end both of them got their inspiration from Swiss made movements. Later edit, thanks to Stephen: “The movement is the first version of the Citizen F-type. This was their first wristwatch, launched in 1931. It was based on a Swiss design and was used in several re-designed forms right through to the 1950s”. The strap is clearly a replacement. I don’t know how the original might have looked like, but I doubt the fact that it was a nato style. Yet again, it might have been. seiko citizen antique military watch   Here is one more piece of information I came across in my searches! Due to my friend Dobashi, now I have this awesome picture inside the firs Citizen factory where the worker coat has the same unusual logo seen in a circle on the movement. It is “CZ”, the Citizen logo. I have never seen this logo before and neither any of my Citizen collectors friends. Maybe this makes it one of the earlier watches EVER made by Citizen!? Year of production – 1931? (then, it’s not a military one) Citizen manufacture first watch All things considered, I look at this watch and I can only imagine Japan before and during WWII and this watch doing it’s job, strapped on the wrist of it’s proud owner.

  1. Hi Bogdan – the movement is the first version of the Citizen F-type. This was their first wristwatch, launched in 1931. It was based on a Swiss design and was used in several re-designed forms right through to the 1950s. The Seiko patent number is a mystery – maybe the case back was a replacement? Citizen’s research institute was called Shokosha.
