Hey thanks for the nice comments everyone. Here is all I know about the watches:
They were purchased at some point by my uncle who resides in Poland.
The company that made these watches is Vostok (Russian Восток). I believe that all of the watches shown are by Vostok, anyway. There are one or two which I'm not completely sure about. A few of these watches are from the
Komandirskie line, others from the
Amphibia line. The latter of which was made popular in the military due to their ability to withstand a 200m depth (!). The early models were created in the 60's and were quite popular by 1980.
In 2006-2008 they did a kind of revival of the
Komandirskie and
Amphibia lines, but I do know that these are not from that time period.
I'll have to ask when my uncle gave these to my family, but I know that the last time my uncle was here was ~10 years ago, so they could be no younger. Another thing that leads me to believe that these are older is the glow-in-the-dark dots painted by each of the hours. If you follow the link in my original post, you can see in the hi-res pictures that the dots are highly imperfect, presumably done by hand.
They are all mechanical watches using jewel bearings rather than quartz. Though this is general less-accurate than electrical watches, Vostok has a good reputation for making accurate watches, even those for marine use (which is pretty difficult for a mechanical timepiece.)
That's about all the information that I have at this point. I'll let you know if I find out more.
