Congrats to me, I managed to flood my 2012 Scuba Dude Vostok Amphibian by swimming with a loose (unscrewed) cap on the winding "head" (whatever you properly call it).
The watch doesn't work any more.
I used the opportunity to open the watch as don't like to open working watches and... I found a surprise surprise!
I describe the surprise in this little video.
As you can see it has a Vostok Europe auto-winding rotor (and Vostok Europe is not necessarily related to the Vostok company proper).
At first, I though that maybe even the movement itself was a Vostok Europe but it is unlikely.
More pictures for your enjoyment.
