OMEGA Speedmaster Moonphase

The Omega Speedmaster Moonphase 304.33.44.52.03.001 has a steel case measuring 44.25 mm across. Thickness runs to 16.85 mm, with a lug-to-lug span of 50 mm. A self-winding column-wheel chronograph, calibre 9904, drives the watch and carries Master Chronometer certification with resistance to magnetic fields up to 15,000 gauss. The blue dial sits under a sapphire crystal treated with anti-reflective coating on both sides. Beyond the chronograph and moonphase display, the movement also shows the date by hand and runs a small seconds subdial, with power reserve at 60 hours. A transparent caseback reveals the finishing, which includes Geneva waves in arabesque. The watch is fitted to a blue alligator leather strap with a steel foldover clasp. Water resistance reaches 100 metres.
