Ref. 310.20.42.50.02.001

The Omega Speedmaster Moonwatch Professional 310.20.42.50.02.001 debuted in 2024 as part of the Moonwatch Professional collection, combining the historically faithful Moonwatch architecture with a two-tone construction in stainless steel and Moonshine Gold. The watch is housed in a 42 mm asymmetrical case crafted from stainless steel, paired with a Moonshine Gold bezel ring featuring a tachymeter scale rendered in black ceramic. The bezel retains the traditional dot over 90 detail. Lug-to-lug measurement is 47.50 mm, with a case thickness of approximately 13.18 mm. Water resistance is rated to 5 bar. Sapphire crystal is fitted to both the front and the caseback, allowing visibility of the movement. The dial is executed in a silver-coloured stepped construction inspired by fourth-generation Speedmaster models. It features applied Moonshine Gold hour markers and an applied Omega logo, with Moonwatch-style hands throughout. The chronograph display consists of a small seconds sub-dial, a 30-minute recorder, and a 12-hour recorder. Powering the watch is the manually wound Omega Co-Axial Master Chronometer Calibre 3861. Certified by METAS, the movement operates at a frequency of 3 Hz, delivers a power reserve of approximately 50 hours, and is resistant to magnetic fields up to 15,000 gauss. The movement features a free-sprung balance with a silicon balance spring and rhodium-plated finishing. The Speedmaster Moonwatch Professional 310.20.42.50.02.001 is fitted with a stainless steel bracelet featuring Moonshine Gold centre links, secured by a foldover clasp with comfort adjustment.
