- No astronaut has set foot on Mars (yet), but that hasn’t stopped Omega, in partnership with the European Space Agency (ESA), from developing the Speedmaster X-33 Marstimer, an analog/digital quartz wristwatch that can track time on the Red Planet as well as on Earth.
- It can also track Mission Elapsed Time (MET) and has three Phased Elapsed Times to track specific events in the MET in either Earth or Mars time.
- In Martian mode, the watch tracks Martian Coordinated Time (MTC), which is the time zone on the Martian prime meridian, as well as two other Martian time zones, and it has three alarms that can be set for either planet.
