Omega Speedmaster X-33 Marstimer

About This Watch

The Omega Speedmaster X-33 Marstimer is the world's first watch to display Mars time, developed in collaboration with the European Space Agency (ESA). A Martian sol (day) is approximately 39 minutes and 35 seconds longer than an Earth day, and the Marstimer tracks both Earth and Mars time simultaneously on its analog-digital display. The thermo-compensated quartz caliber 5622 provides functions including chronograph, alarm, countdown timer, Mission Elapsed Time (MET), and Phase Elapsed Time (PET) — all critical functions for space missions. The Grade 2 titanium case keeps weight to just 108 grams despite the 45mm diameter. The analog hands display standard time while the digital segment display handles the specialized functions. The X-33 lineage started as the official watch for astronauts and cosmonauts aboard the International Space Station. The Marstimer takes this further by preparing for humanity's next great space frontier. This is not a concept watch — it is a genuine instrument designed for the era of Mars exploration.
