The OMEGA Speedmaster Moonphase Chronograph 44.25mm (Ref. 304.33.44.52.01.001) combines the Speedmaster’s legendary lunar exploration heritage with a sophisticated moonphase complication featuring a metallic crystal disc microstructured to obtain a high-resolution photo-realistic image of the moon at 6 o’clock, two infinitely small yet accurate representations tracking the lunar cycle. The black sun-brushed dial with rhodium-plated indexes creates elegant depth whilst the black ceramic bezel ring with Liquidmetal tachymeter scale maintains authentic Speedmaster character.

At 44.25mm with 16.85mm thickness through stainless steel construction, this provides commanding presence whilst the microstructured moonphase disc represents a technically distinct approach to lunar display compared to conventional printed or engraved alternatives. The black sun-brushed dial with small seconds and 12-hour and 60-minute recorders provides comprehensive chronograph layout alongside the moonphase.

The Co-Axial Master Chronometer Calibre 9904 delivers 60-hour power reserve with 15,000 gauss magnetic resistance through METAS certification whilst the column wheel chronograph with two barrels mounted in series provides precise timing functionality including date indication by hand. The silicon balance spring and rhodium-plated finish with Geneva waves in arabesque demonstrate exceptional movement specification.

The scratch-resistant sapphire crystal with anti-reflective treatment on both sides ensures optimal clarity whilst the black alligator leather strap with non-grained calf lining and foldover clasp provides sophisticated daily wear. The 100m water resistance covers practical requirements. Adding a photo-realistic microstructured moon to the Speedmaster’s chronograph specification creates a watch that bridges the brand’s space heritage and traditional watchmaking complication in a single reference.
