Speedmaster Professional Moonwatch 3861 Moonshine Gold / Green / Bracelet

Ref. 310.60.42.50.10.001

The OMEGA Speedmaster Moonwatch Professional 310.60.42.50.10.001 debuted in 2022 as a full precious-metal execution of the Moonwatch, rendered entirely in 18K Moonshine Gold. The 42 mm asymmetrical case follows the established Moonwatch Professional architecture, with twisted lugs, crown guards, and sapphire crystal on both the dial side and the case back. The bezel is fitted with a green ceramic insert featuring a Ceragold tachymeter scale, combining a high-contrast appearance with long-term durability. The stepped dial is executed in green and features applied hour markers and an applied OMEGA logo, all crafted in 18K Moonshine Gold. The chronograph display follows the classic Moonwatch configuration, comprising a small seconds display, a 30-minute recorder, and a 12-hour recorder. The hands are finished to match the case material, ensuring visual consistency across the dial. Inside, the watch is powered by the manually wound OMEGA Co-Axial Master Chronometer Calibre 3861. This movement drives the timekeeping and chronograph functions and is certified by METAS, guaranteeing resistance to magnetic fields up to 15,000 gauss, as well as compliance with stringent standards for precision, power reserve, and overall performance. The movement is visible through the sapphire case back, revealing its rhodium-plated finish and Geneva-style decoration. The watch is fitted with an 18K Moonshine Gold bracelet featuring polished center links and a foldover clasp with comfort adjustment. Water resistance is rated to 50 metres.
