This is a Vostok Amphibian with a limited edition of 300 watches. The watch is a reissue of the famous NVCh-30 with the 350 case. This watch has an upgraded movement – the automatic 2415b with 31 jewels – compared to the original 2209 manual movement from the original NVCh-30 in the 350 case. It’s water proof down to 300 meters, like the original watch.
Mineral crystal.
This particular watch has the swing lugs but it’s easy to change to the wire lugs with a Nato strap.
