OMEGA Speedmaster Moonwatch Professional Stem Winding – 310.30.42.50.04.001

The Speedmaster Moonwatch stands as an emblem of Omega's pioneering spirit, having accompanied astronauts on all six lunar landings. Crafted from stainless steel with a polished-brushed bracelet, its 42 mm case boasts a distinctive asymmetrical design reminiscent of its moon-worn predecessor. The white lacquered step dial, with applied Omega logo and indexes, pays homage to the iconic ALASKA I Prototype, featuring contrasting black details and glossy lacquered finish, a first for Moonwatch dials.

Protected by scratch-resistant sapphire crystal on both front and back, the watch houses the Omega Co-Axial Master Chronometer Calibre 3861. This manual-winding movement, certified by METAS, drives the small seconds sub-dial and chronograph functions with precision. Resistant to magnetic fields up to 15,000 gauss, it ensures accuracy and reliability even in challenging environments.

The dial's red accents, including the Speedmaster name and seconds hand tip, draw inspiration from astronaut suits and the ALASKA I watch protective case. The bracelet, featuring a foldover clasp with a comfort setting and adorned with a polished Omega logo, exudes refinement and practicality.

Technical specifications include a 42 mm case diameter, 47.5 mm lug-to-lug distance, and 13.2 mm thickness, with water resistance up to 50 meters. Weighing approximately 140 g, the watch offers both style and substance, embodying Omega's commitment to excellence in watchmaking.
