OMEGA Speedmaster Moonwatch Professional Stem Winding – 310.20.42.50.02.001

The Omega Speedmaster Moonwatch Professional, a symbol of OMEGA’s pioneering spirit, has been worn by astronauts on all six moon landings. This 42 mm model features stainless steel and 18K Moonshine Gold, with sapphire crystal on the front and caseback. Inspired by the 4th generation Speedmaster, it has an asymmetrical case, a black ceramic bezel ring with a tachymeter scale, and the famous "dot over ninety" in OMEGA Ceragold.

The sun-brushed silvery dial includes an applied OMEGA logo, 18K Moonshine Gold hands, and subdials for small seconds, 30-minute, and 12-hour recording. Powered by the OMEGA Co-Axial Master Chronometer Calibre 3861, it features anti-magnetic properties, chronograph functions, and Master Chronometer certification.

The polished-brushed bracelet comes with a comfort release adjustment system. The watch is water-resistant up to 50 meters and weighs approximately 161g. OMEGA’s exclusive Moonshine Gold, created in 2019, offers a paler hue than traditional 18K gold and resists fading. With a 50-hour power reserve and superior precision, the Speedmaster Moonwatch remains an iconic timepiece, blending historical design with modern reliability.
