The Omega Speedmaster Professional Moonwatch Ref. 310.30.42.50.01.001 retains the traditional character of the Moonwatch while incorporating Omega's current-generation movement and bracelet design. It features a 42mm stainless steel case, black stepped dial, Hesalite crystal, black tachymeter bezel, solid caseback, and tapered stainless steel bracelet.

The watch is powered by the manual-winding Omega Co-Axial Master Chronometer Calibre 3861, offering approximately 50 hours of power reserve and METAS Master Chronometer certification.

This 2025 example comes as a full set and remains in excellent overall condition. There are a few very light, difficult-to-see hairlines around the case and bracelet from normal use. One tiny flea-bite nick is present on the side of the case.
