I was thinking about what would go into a watch collection centered around space travel. Speedmaster (obviously) Sturmanskie (Yuri Gagarin's watch) Bulova Moonwatch Fortis Cosmonauts Chronograph What else?
Bulova Accutron 214 Spaceview, (including deployment in Telstar and endorsement of Accutron as used by X-15 pilots).
Bulova Astronaut (they were Omega's main competition for the NASA wristwatch contract and were standard issue for U-2 pilots)
