Here are a few watches from my personal collection that are know or suspected to have been in space.
The first is obvious, probably the most well know space watch of all time.
The Cal.321 Pre-Pro Speedmaster.
Most space watches are really pilot's watches, probably because most astronauts really were pilot's, and took their trusty watch with them in space. Like the Rolex GMT-Master.
Bulova tried to push their brilliant, but unfortunately quickly obsolete 'tuning fork' watches for space use. I'm not sure that they were ever used as wristwatch in space (I believe they were) but if I recall correctly, they did provide the on board timers for several missions. Anyway this watch is not called the Accutron Astronaut for nothing.
From Russia, the Strela. Not sure if this was the exact version that went into space, but it was either this one, or one very similar to this one.
Fortis has been in space. Again I'm not sure if it was this exact model, but it may very well have been. The Fortis Cosmonaute.
I believe it's pretty well documented that this one has been in space. The Omega Flightmaster.
Another pilot's watch that has most probably been in space. Not issued, but as a privately owned watch. The Glycine Airman.
Switching to a more modern watch. Designed specifically for space use, and if I'm not mistaken the official watch for several missions, the Omega X-33.
And finally, just for fun. I bought this one in Shanghai. The Fyita 'Space-watch' from China. This is really a special 'commemorative' edition. I believe that the Fyita that went into space was slightly bigger, and had a modified movement. But I still don't know exactly.
