Manual, I think the whole auto rotor in zero gravity was an unknown so they played it safe.
@TRA you have to remember how long ago this watch was conceived and what else was available, it repeatedly beat the best in competition in the NASA tests. There’s a ton of really good info out there about the test criteria and how the Speedy was used in space. I’ll post some links later but I’m out today.
It’s OK money I guess, I think you can find tidier though. Notice all the lume pips except the ‘11’ have departed and the hour hand looks ripe to shed its tritium. At least it’s had it’s date wheel replaced - the originals get brittle and lose a tooth - mine sticks on the 28th every month...
Old watches that would be 8 winds.
