Moonwatch Omega Co-Axial Master Chronometer Moonphase Chronograph 44.25 mm

Steel on leather strap

304.33.44.52.03.001

Description

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 two infinitely small yet photo-realistic moons.

This 44.25 mm model features a blue sun-brushed dial, with rhodium-plated indexes. At 6 o'clock is the accurate Moonphase indication, which features a metallic crystal disc microstructured to obtain a high resolution image of the moon.

The stainless steel case is complemented by a blue ceramic bezel ring with Liquidmetal® tachymeter scale and presented on a blue leather strap with a polished-brushed foldover clasp.

Powering the timepiece is the OMEGA Co-Axial Master Chronometer 9904, which has been officially certified by METAS.
