I have a 1950s mark 2 Shturmanskie as my main watch, the same model Yuri Gagarin wore into space. It's a 'frankenwatch' in that it's been assembled from parts of other watches, albeit in this case they're the right parts from the right period except the dial, which is a reproduction to avoid the considerable amount of radium the Soviets liked to put in their pilot watches.

Now that is an unreliable watch! It'll usually lose maybe a minute a day which is actually pretty decent for something from when Khrushchev was in power, but it likes to randomly stop or occasionally start running fast or slow according to its mood. I'm not sure how much of it is because it's a Soviet frankenwatch and how much is that it's hard to find people who'll work on Soviet watches in the UK.
