OMEGA Speedmaster Moonphase (Blue Side Of The Moon)

Omega's Speedmaster Moonphase Blue Side Of The Moon, reference 304.93.44.52.03.001, comes in a 44.25 mm blue ceramic case. It measures 17.04 mm thick with a lug-to-lug span of 49.8 mm. A sapphire crystal with anti-reflective treatment on both sides covers the blue dial. The self-winding calibre 9904 drives the watch, a Master Chronometer movement with column wheel, Co-Axial escapement and silicon balance spring, certified to resist magnetic fields up to 15,000 gauss. Its power reserve runs to 60 hours. As a chronograph it pairs a moonphase display with a small seconds hand, a date indication and recorders for the chronograph minutes and hours, and the sapphire caseback shows the movement. The blue alligator leather strap closes with a ceramic foldover clasp. Water resistance stands at 50 metres.
