Omega Speedmaster Professional Moonwatch 3861 Stainless Steel / White / Sapphire Ref. 310.32.42.50.04.002

The Omega Speedmaster Moonwatch Professional 310.32.42.50.04.002 debuted in 2024 as part of the updated Moonwatch Professional range featuring a white dial, drawing visual inspiration from historic Speedmaster references worn during lunar missions. The watch is housed in a 42 mm stainless steel asymmetrical case measuring 47.50 mm lug to lug and 13.18 mm in thickness. Water resistance is rated to 5 bar. A black anodised aluminium bezel with tachymeter scale surrounds the dial and retains the traditional dot over 90 detail. The front is fitted with a scratch-resistant sapphire crystal featuring anti-reflective treatment on the inside, while the caseback is also executed in sapphire, allowing visibility of the movement. The white lacquered step dial references the fourth-generation Speedmaster design and features applied hour markers and an applied Omega logo. Black printed details provide contrast, while Moonwatch-style hands are used throughout. The chronograph layout consists of a small seconds display, a 30-minute recorder, and a 12-hour recorder arranged in a classic tri-compax configuration. Powering the watch is the manual-winding Omega Calibre 3861, a Co-Axial Master Chronometer movement certified by METAS. Operating at a frequency of 3 Hz, the calibre provides a power reserve of approximately 50 hours and offers resistance to magnetic fields up to 15,000 gauss. The movement features a free-sprung balance with a silicon balance spring and is finished with rhodium-plated components. The Speedmaster Moonwatch Professional 310.32.42.50.04.002 is delivered on a black leather strap secured with a foldover clasp.
