In the space race of the 1960’s Nasa decided to use the Omega Speedmaster for their space missions as it was the only watch to survive their extensive testing. For Omega this presented a marketing paradise and the Speedmaster professional Moonwatch came into existence. This 1971 watch is in very good condition, but the movement is dry and needs a service.
This watch is actually for sale and the owner is open for good offers. I would buy this example myself if I could afford it!
