While I'm being a total Sinn geek, did you know that the Sinn 141 S was one of the first automatic watches worn in space?
It was on the wrist of Reinhard Furrer during Spacelab D1, a similar watches were also worn on Mir and during Spacelab D2
He bought the watch privately and wanted to show that an automatic watch would still wind itself without the help of gravity
Turns out Cmdr William Pogue wore a non-approved Seiko 6139 during Skylab 4 about 11 years before this and so that was the actual first automatic watch in space but nobody knew that at the time
