About This Reference
The Speedmaster Moonphase Chronograph Master Chronometer was introduced in 2016, adding a moonphase complication to the Speedmaster family in a way that stays true to its space-race legacy. The moonphase display at 6 o'clock uses a metalized mineral crystal disc micro-structured to produce a high-resolution image of the lunar surface — detailed enough to show an astronaut's footprint on the moon. The 44.25mm stainless steel case is topped with a blue ceramic bezel ring featuring Omega's Liquidmetal™ tachymeter scale, and the blue sun-brushed dial pairs rhodium-plated indexes with a date sub-dial at 9 o'clock and a 12-hour chronograph counter at 3. Powering it all is the calibre 9904 — a 54-jewel, METAS-certified Master Chronometer with twin barrels, an Si14 silicon balance spring, and magnetic resistance exceeding 15,000 gauss.
