Anybody here own one? I am serously considering buying an Omega "MoonWatch" Speedmaster Professional and it has a hand winding mechanism. I am not sure I can get used hand widning this watch on a regular basis. How often do you have to wind these these watches? They do sell an automatic version of this watch but then this would not make it the original version of the "MoonWatch" that NASA chose for all manned space mission in the early 1960's.
