OMEGA Speedmaster Moonphase

Omega's Speedmaster Moonphase 304.93.44.52.99.002 is a chronograph in a 44.25 mm platinum case. The case measures 17.05 mm thick with a lug-to-lug span of 50 mm. A sapphire crystal with anti-reflective treatment on both sides covers the grey dial. Inside is the self-winding calibre 9905, a column-wheel chronograph with Co-Axial escapement and a silicon balance spring, certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss, with 60 hours of power reserve. Beyond the chronograph function, the watch adds a moonphase display, small seconds and a date indication read by hand. The display back shows off the 18K Sedna gold rotor and balance bridge. A red alligator leather strap closes with a platinum foldover clasp, and the case holds a 100 metre water resistance rating.
