I'm a big fan!
I was in Minsk in 2002, and spotted some watches with cool dials. I picked what turned out to be a Vostok Amphibia KGB and a Partner Submariner. They were about $12 each!
Then I did a bit of research and picked up a lovely retro styled Poljot 3133 Navitimer "Blue Angels" limited edition.
This commemorates the first time a non-Warsaw Pact display team performed in Russia.
The Poljot is about the same quality wise as a Prospex Seiko. It is also very hardy. I've had it serviced twice since I got it in 2003.
There is an outstanding chap in Germany, Julian who runs Poljot24.de who can do all the servicing and restoration from Soviet right up to the modern stuff. You'll find it hard to see a bad word about him. He has a load of NOS for servicing and rejuvenation.
I love these because they are quirky, but rugged and the very definition of a tool.
I've still got my eye out for a proper Soviet Sturmanskie 3133, as was issued to air force pilots.
The 3133 movement is based on the ETA 7733 movement, and has many interchangeable parts, but it was somewhat ruggedised and made more durable for military use.
An unmolested original can go around €1,000 and there is a minefield of fakes, reproductions and frankenwatch creations.
Best go with a recognised dealer who can source and verify.
