Moonwatch Omega Co‑Axial Master Chronometer Moonphase Chronograph 44.25 mm Blue Side Of The Moon
Blue ceramic on leather strap
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 "Blue Side of the Moon" takes its names from the colour of the dark blue sky.
The 44.25 mm watch features a blue ceramic case complemented by a blue ceramic bezel ring with Liquidmetal™ tachymeter scale. It is presented on a blue leather strap with a blue ceramic, ceramised titanium foldover clasp.
The blue ceramic dial includes 18K white gold indexes and hands. At 6 o'clock is the accurate Moonphase indication, which features a blue ceramic moonphase disc with near and far sides of the moon in LiquidMetal™.
Powering the timepiece is the OMEGA Co-Axial Master Chronometer 9904, which has been officially certified by METAS.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
