Note he was wearing a personal Rolex Sea Dweller wrist watch, which he also used as an aquanaut during several NASA diving projects, such as NEEMO. Rolex has the most different space-flown wrist watch versions, as at least 8 were worn in space (GMT-master, GMT-master II, Datejust, Daytona 6263, Submariner, Sea Dweller, Yachtmaster and Oysterquartz).
