thanks for the quick reply. I believe it's an original Poljot. But you know what they say about believing...
I just got it a few days ago from a friend who bought it in Russia several years ago. I don't have any clue when it was made, so actually that's part of my inquiry.
Regarding your hint with timezone.com - I actually just posted it on watchuseek - but will look into timezone.com as well. I hope they don't mind crossposting ;o.
