Made in conjunction with the European Space Agency (ESA), OMEGA’s Speedmaster X-33 Marstimer is everything the name suggests.

Cased in grade 2 titanium, the unique 45 mm chronograph can display true solar time at any location on Earth and Mars. Made possible by a new microcontroller, developed and programmed to implement the equation of time for the two planets. This ability to display true solar time at any location allows the watch’s innovative solar compass to find true north on Earth and Mars with exceptional precision. The watch also displays the solar longitude of Mars as well as the mean solar time for three different locations (at the prime meridian two user-defined locations): allowing for Mars’ 2.7% longer days.

Its classic black dial provides a contrasting backdrop for the multiple analogue and digital readings, made even clearer by Earth and Mars symbols to distinguish which particular functions are in use. Circling the dial is an oxalic anodized aluminium bezel ring in red hematite, reminiscent of Mars’ distinctive dust. This striking shade is also present on the seconds hand, which has a black to red hematite gradient.

Turning the watch over reveals a caseback embossed in the centre with OMEGA’s famous Speedmaster wording and Seahorse logo. Circled by the words SPEEDMASTER X-33 MARSTIMER, ESA TESTED AND QUALIFIED. Providing the power is OMEGA’s 5622 Calibre.

For those wishing to switch out the grade 2 and 5 titanium bracelet, the Marstimer also comes with a dedicated NATO strap. This is included in the special watch roll, which has a nod to the red planet on its inner lining: a reproduction of Hebes Chasma, a unique steep-sided canyon on the surface of Mars.
