Omega Speedmaster Moonphase 44.25mm 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.

A tachymeter watch has a function for measuring speed. It is a chronograph with a graduated dial on which speed can be read in kilometres per hour based on a 1000 metre distance.
Transparent caseback
A transparent caseback – frequently made of sapphire – makes it possible to see the movement inside the watch.
