Speedmaster Professional Moonwatch Co-Axial Master Chronometer

The Speedmaster Professional remains the only watch qualified by NASA for extravehicular activity, a distinction earned through decades of proven reliability. This 2022 Master Chronometer iteration features Omega's caliber 3861 manual-wind movement—a refinement of the legendary caliber 1861—paired with upgraded chronograph performance and Co-Axial escapement technology.

This steel case measures 42 mm with a black dial, luminous indices and hands, and a plexiglass crystal that honours the model's heritage. It comes in good condition with its original box and papers, powered by a manual movement offering 48 hours of power reserve.
