Mayak Atom

Mayak Atom – movement cal. 2603, chrome plated case. I never heard anyone using this name, its just my idea, baically first thing that comes to my mind when I see this watch. I have seen couple of watches with this uncommon dial but usually they are very worn. Take a look at this interesting strap with a photo of Soviet cosmonaut German Titov who became the second human to orbit the Earth.
