The OMEGA Speedmaster is one of OMEGA's most iconic timepieces. Having been a part of all six lunar missions, the legendary Speedmaster is an impressive representation of the brand's adventurous pioneering spirit. This model features a bold brown dial with a scratch-resistant sapphire crystal. A small seconds dial, 30-minute recorder and 12-hour recorder grace the dial along with a central chronograph hand. The black bezel, with its tachymetric scale, is mounted on a 42 mm stainless steel case, and the watch is presented on a stainless steel bracelet. At the heart of this chronograph is OMEGA's mechanical calibre 1863, the famous manual-winding movement that was worn on the moon, visible through the transparent caseback.
