OMEGA Speedmaster Moonwatch Professional Stem Winding – 310.32.42.50.04.001

The OMEGA Speedmaster Moonwatch Professional is more than a timepiece—it’s a living legend. Worn on all six moon landings, this iconic chronograph captures OMEGA’s pioneering spirit with every detail. Crafted in stainless steel, the 42mm case features sapphire crystal on both the front and back, revealing the beauty of the manual-winding Co-Axial Master Chronometer Calibre 3861 movement.

Inspired by the 4th generation Speedmaster worn on the moon, this model includes a white lacquered step dial with applied OMEGA logo, Moonwatch-style hands, and the signature dot-over-90 bezel in black anodised aluminum. The integrated black rubber strap features a lunar surface pattern on the underside—a subtle nod to its spacefaring heritage.

Inside, the Calibre 3861 movement delivers exceptional precision and performance with its Co-Axial escapement, silicon balance spring, and resistance to magnetic fields up to 15,000 gauss. With a 50-hour power reserve and METAS certification, it offers superior shock resistance, long-term durability, and less frequent servicing.

Water-resistant to 50 meters and backed by a 5-year warranty, the Speedmaster Moonwatch is built for those who appreciate timeless design, technical innovation, and the enduring legacy of space exploration.
