Bringing together luxury and performance, Omega has consistently redefined state-of-the art mechanical watchmaking since 1884 - paving the way for precision timepieces that are captivating, inspiring, and beautifully engineered. Omega have been witness to some of mankind’s most historic moments: from having supplied NASA with the Speedmaster Professional which went on to become the first watch worn on the moon during the Apollo space missions, to being the official timekeeper to the Olympic games, witnessing some of sport’s greatest achievements. As well as beautifully measuring every moment on earth; this timepiece follows the phases of the moon, which makes perfect sense given that the Speedmaster was the first watch ever to be worn on the lunar surface. As a Master Chronometer, the Moon phase celebrates another pioneering moment: OMEGA's exacting new standard of testing approved by METAS in 2015.
