Moonwatch Omega Co‑Axial Master Chronometer Moonphase Chronograph 44.25 mm
Platinum on leather strap
The Speedmaster is one of OMEGA’s most iconic timepieces, having been a part of all six lunar missions. Celebrating that history, this Moonphase model enhances the classic Speedmaster design with exquisite materials and precision.
The 44.25 mm case is made from platinum-gold, while the blue ceramic bezel ring includes a brushed platinum Liquidmetal™ tachymeter scale.
The sand-blasted platinum-gold dial is brought to life by its 18K white gold indexes that are set with baguette-cut diamonds. Complementing that colour is the blue ceramic moonphase disc at 6 o'clock that features two moons in platinum Liquidmetal™. The dial is completed by a magnified hand on the date subdial as well as blackened hours, minutes and central seconds hands all with white Super-LumiNova.
Presented on a blue leather strap, the timepiece is powered by the OMEGA Master Chronometer Calibre 9905, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
