Hi Frenchiexu. Welcome to the forum !
That is such a terrific looking watch. Love that submarine, and just the whole look of the dial,
and bezel. Cool strap also with it ! ..I Don't have one or know much about these watches, but
it looks like a Vostok Komandirskie. ..Vostok has evidently been making these awesome
watches for more than 50 years, with each not only being very well made, and tough, but also
keeping great time. Seems like the dials often commemorate various important Russian
events as well. On top of that there are various different versions like yours that have been,
and are still being made today with different movements, cases, and dials. Found this info
at webwatchworld.com. Check out this link and more below if you like. I hope this helps you
out...
