I am selling my Speedmaster Professional, 310.30.42.50.01.001. It is the version with solid case back and Hesalite crystal, in keeping with the original Moonwatch.
Watch is in perfect working condition. Winding is smooth. The pusher actions are crisp and the chronograph functions flawlessly. Time keeping is of course within master chronometer spec.
Watch was purchased in Oct 2021.
Please dont hesitate to contact me for more photos and info.
In-person transaction preferred.
