This Vostok naval "Commander" watch has a cal.2414A movement with 17 jewels, crown guard and screw-down clasp. With Vostok's special "rocking crown" system (impact protection). The watch is waterproof up to 200m according to the manufacturer, but I have not tested it. However, the seals are new and treated with silicone grease, but since it is an old vintage piece, it is worth taking care of this. It's a rare, collector's Soviet watch, with an original, superb 'battle-roasted' patina that gives the watch a real vintage vibe. This watch has a completely new letherette strap, serviced c.a. a half yaer ago and is good technical condition, it's running perfectly. It's in great demand among military, thematic or sovjet watch collectors. The special feature of the watch is that, based on the back, it is still Soviet, but it is not written on the dial. These watches were made during the disintegration of the Soviet Union. The manufacturer “didn't know” what to write on it. From this you can be sure that the watch was made between June 1990 and December 1991.
