We like our astronaut watches, and one’s just hit us out of the wild blue yonder — the Halda Space Discovery (~$13,200), a beautiful piece of technology that hides its dual personality a hell of a lot better than Dr. Jekyll. The watch features interchangeable timekeeping modules: the Space Module (electronic) and the Mechanical Module (well… mechanical). Both are integrated into the bracelet so well that it’s difficult to tell they’re swappable pieces.
The Sinn 140 A Space Chronograph ($4,930) is a Limited Edition update of the 140 S that German physicist/astronaut Reinhard Furrer wore on his voyage to SpaceLab in 1985. Furrer’s 140 S was reputed to be the first automatic chronograph to be worn in space (the Seiko 6139 may have beaten it though), proving once again that a self-winding watch would work just fine without gravity.
