Omega Speedmaster Moonphase Co-Axial Master Chronometer: Iconic Lunar Chronograph

The Omega Speedmaster Moonphase Co-Axial Master Chronometer continues the legendary Speedmaster legacy, famously accompanying all six lunar missions. This timepiece introduces a dual moonphase display with miniature moons rendered in remarkable detail, allowing lunar tracking alongside the classic chronograph functions.
Dial and Design
The sun-brushed grey dial features 18K gold hands and hour markers, while the green ceramic bezel is enhanced with a Ceragold tachymeter scale. The symmetrical dial layout with twin-hand subdials ensures readability and aesthetic balance. At 6 o’clock, the moonphase utilizes a microstructured metallic crystal disc displaying NASA imagery, including an astronaut’s footprint, tracking the 29.5-day lunar cycle with correction required only once every 10 years.
Movement and Technical Excellence
Powering this watch is the Omega Co-Axial Master Chronometer Calibre 9904, certified by the Swiss Federal Institute of Metrology (METAS). It resists magnetic fields up to 15,000 gauss and offers a 60-hour power reserve. The sapphire crystal caseback allows a full view of the exquisite movement.
