The Speedmaster Moonwatch is one of the world’s most iconic timepieces. Having been worn by astronauts on all six moon landings, the legendary chronograph is an impressive symbol of OMEGA’s pioneering spirit.

This 42 mm bi-colour model in stainless steel and 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 includes an asymmetrical case with a black ceramic bezel ring, with its tachymeter scale and famous “dot over ninety” in OMEGA Ceragold™.

The PVD-treated 18K Sedna™ Gold “step” dial is sun-brushed and presented with applied OMEGA logo and indexes, 18K Sedna™ Gold hands, and black coated subdials including a small seconds recorder, 30-minute recorder, and 12-hour recorder.

The watch is worn on a polished-brushed bracelet with OMEGA’s patented comfort release adjustment system, and is powered by the OMEGA Co-Axial Master Chronometer Calibre 3861.
