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. 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.Circled by the words SPEEDMASTER X-33 MARSTIMER, ESA TESTED AND QUALIFIED. 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.
