Omega Speedmaster Professional Moonwatch 3861 Canopus Gold - Diamond / Silver / Bracelet Ref. 310.55.42.50.02.001

The Omega Speedmaster Moonwatch Professional 310.55.42.50.02.001 debuted in 2023 as a precious-metal interpretation of the Moonwatch, distinguished by its use of 18K Canopus Gold and a diamond-set bezel. The watch is housed in a 42 mm asymmetrical case crafted from 18K Canopus Gold, paired with a matching five-arched-links-per-row bracelet. Sapphire crystal is used on both the front and the caseback. Surrounding the dial is a diamond-paved bezel, adding a decorative element while retaining the characteristic Moonwatch case geometry derived from the fourth-generation Speedmaster worn during the Apollo missions. The dial is executed in a sun-brushed silvery finish, with applied hour markers and matching hands in 18K Canopus Gold. The chronograph layout follows the classic Moonwatch configuration, with a small seconds display, a 30-minute recorder, and a 12-hour recorder arranged across the dial. Legibility is maintained through tonal contrast and precise finishing rather than colour accents. Powering the watch is the manual-winding Omega Co-Axial Master Chronometer Calibre 3861. Certified by METAS, the movement offers resistance to magnetic fields up to 15,000 gauss and meets stringent standards for precision, power reserve, and performance. It drives the central chronograph seconds as well as all subsidiary indications and is visible through the sapphire caseback, where the precious-metal construction and refined finishing underscore the watch’s position within the Moonwatch lineage. This reference combines the historically grounded design of the Speedmaster Moonwatch with elevated materials and gem-setting, resulting in a version that remains mechanically aligned with the Professional models while clearly set apart through execution and finish.
