Just caught an Iskra Pocket watch made in 1957. It seems like a rare watch because I never saw another one here. The first thing that strike me is that this might be a commemorative watch celebrating the 40th anniversary of October revolution in 1917, and Iskra is the name of the party newspaper. According to Mark's site, it has a different movement that is signed Iskra. Does anyone who has an Iskra that was made in other years?
BTW, also caught two more Vostoks, and one of them is a 4 hour version.
