Old watches that would be 8 winds.
I thought they were automatic?
Not possible while in either micro or no gravity. It has to be either manual or battery. The rotor requires gravity to work
That’s what they thought when they were first looking for watches to go into space but pretty sure they’ve discovered that automatics will self-wind in zero gravity (cos of inertia).
