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 OMEGA Speedmaster Broad Arrow 1957 Chronograph features a black dial graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph and “broad arrow” hour and minute hands, as well as a scratch-resistant sapphire crystal. There is a date window at the 6 o’clock position. The bezel, with its tachymetric scale, is mounted on a 42 mm stainless steel case and presented on a stainless steel bracelet. At the heart of this timepiece is the Co-Axial calibre 3313 which is visible through the transparent caseback.
