Description

This is an original 1971 Omega Speedmaster Professional Moonwatch, a rare NO NASA chronograph (Ref. 145022-71 ST), in its original, unpolished condition, fully operational and authentic. 

This particular reference marks the final production using the older “step” dial, with its unique feature being the NO NASA caseback. This variant emerged during a brief period when Omega and NASA were finalizing their agreement regarding the caseback inscriptions, resulting in a limited number of watches with a plain caseback, also referred to as the C1 back.

The original case retains its vintage charm, showing signs of use that enhance the watch’s character and authenticity. It has never been touched or polished. 

This watch is powered by an Omega cal. 861 movement, which operates flawlessly and maintains excellent time. The chronograph functions are fully operational. This watch has undergone professional servicing and comes with our 6-month guarantee.

The movement, with a serial number in the 32 million range, is correctly matched to this Moonwatch reference. The case back is original to this model. 

The original black “step” tritium dial is in very good condition, displaying a light, even time patina and only minor oxidations.

This timepiece is also equipped with an original Omega 1171/1 steel bracelet from the 1980s. The bracelet is in good, used, unpolished condition

We guarantee this watch to be original, in excellent working condition, and it will be delivered with our 6-month guarantee and certificate of originality.

We welcome international buyers and offer shipping to most countries.
