Speedmaster Moonwatch Moonphase Chronograph 44.25mm

From the retailer listing

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 grey sun-brushed dial, with diamond polished 18K yellow gold indexes and hands. 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-18K yellow gold case is complemented by a green ceramic bezel ring with Ceragold™ tachymeter scale and presented on a grey 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.
