Moonphase Speedmaster Sedna™ gold Master Chronometer 304.63.44.52.01.001

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 a black sun brushed dial, with diamond polished 18K Sedna™ gold indexes and hands. At 6 o'clock is the accurate Moonphase indication, which features an 18K Sedna™ gold hand-engraved moon disc, filled with enamel and sprinkled with silver powder to represent the stars. Cased in 18K Sedna™ 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 Sedna™ gold foldover clasp. Powering the timepiece is the OMEGA Co-Axial Master Chronometer 9905, which has been officially certified by METAS.
