Speedmaster X-33 Marstimer Titanium / Black / Bracelet

In Context

At 45 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 14.9 mm it is a tall case, and it will catch on a cuff. The sapphire crystal will resist everything short of deliberate abuse. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

It is quartz, so it will hold time far more closely than any mechanical watch here, and asks for a battery every few years rather than a service.

318.90.45.79.01.003 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a titanium, aluminium case. Beyond the time it carries a chronograph.

Highly precise, thermo‑compensated, multi‑functional quartz movement with special functions developed, tested and qualified by the European Space Agency (ESA). Calibrated to power multiple digital and analogue displays. Analogue functions include hours, minutes and seconds. Digital functions track time zones and date on Earth and Mars. The Mars functions can track the rover’s mission on the red planet, while the addition of a solar compass allows the watch to find true north on both Earth and Mars. Also included are traditional Speedmater Skywalker X33 functions, such as MET (Mission Elapsed Time), PET (Phase Elapsed Time), Alarms and perpetual calendar.
