The Speedmaster is one of OMEGA's most iconic timepieces, having been a part of all six lunar missions. Taking the spirit of exploration a step further, this new Moonphase features a hand-engraved representation of the moon. This 44.25 mm model features an opaline silvery dial, with diamond polished 18K yellow gold indexes and hands. At 6 o'clock is the accurate Moonphase indication, which features an 18K yellow gold hand-engraved moon disc, filled with enamel and sprinkled with silver powder to represent the stars. Cased in 18K yellow gold and circled with a black ceramic bezel ring with Ceragold tachymeter scale, this watch is presented on a black leather strap with a polished-brushed 18K yellow gold foldover clasp. Powering the timepiece is the OMEGA Co-Axial Master Chronometer 9905, which has been officially certified by METAS.
