Moonwatch Professional Speedmaster Sedna™ gold Master Chronometer 310.60.42.50.01.001

The Speedmaster Moonwatch is one of the world’s most iconic timepieces. Having been a part of all six moon landings, the legendary chronograph is an impressive representation of the brand’s adventurous pioneering spirit. Presented on a five-arched-links-per-row bracelet, this 42 mm Moonwatch in 18K Sedna™ gold features sapphire crystal glass on the front as well as on the caseback. Inspired by the 4th generation Speedmaster style worn on the moon, it also includes an asymmetrical case, black step dial and the famous dot over 90 on the anodised aluminium bezel ring. The watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 3861, which powers the small seconds sub-dial, 30-minute recorder and 12-hour recorder, along with the central chronograph function.
