When I set out to write a piece about the Chaika 3050, the first ever quartz movement produced in the Soviet Union, I did my due diligence by checking past threads on WUS to ensure I wasn't missing any important details. While this isn't a particularly popular model, its importance as the first quartz movement from the USSR does represent an important milestone in Soviet horology, so I wanted to get my facts right.
Well, after discovering this thread, I gave up: https://www.watchuseek.com/f10/chaika-3050-kr-first-soviet-quartz-watch-848468.html. The author, vpn, covers everything. Read up! I cannot think to add anything more.
Except some photos and videos
The reason for the video is to properly illustrate how this movement functions. I was quite surprised upon opening the case as I haven't seen a quartz with moving parts before (maybe this is common -- I don't study quartz movements closely). In addition, you can definitely tell this is an early mechanism. In stark contrast to the crisp, immediate "tick" of modern quartz movements, this is more of a slow "blub" from one second to the next. Interesting to see in action.
The paperwork is also curious. I cannot read Cyrillic, but the papers appear to depict a basic rendering of how the quartz mechanism works. I can't imagine any mechanical watches offering a similar explanation on the receipt. This was pretty advanced stuff!
