Description

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 Moonwatch Professional Moonphase features a blackened aventurine dial graced by a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph hand. A fourth sub-dial, at the 12 o’clock position, has moonphase and date indicators. The bezel, with its black ceramic tachymetric ring, is mounted on a 44.25 mm stainless steel case and is presented on a matching bracelet. At the heart of this timepiece is OMEGA’s mechanical calibre 1866, a manual-winding movement visible through the transparent caseback.
