Did you hear "Mars Time" from
AirSpace, the podcast from the Smithsonian's National Air and Space Museum, down the street from ThinkGeek World Domination HQ? If you missed it, it was about how trying to keep your body synced to a Mars day, 40 minutes longer than an Earth's Day, wreaks havoc on your naturally circadian body. Apparently beanbag chairs and ice cream makes it better. That's pretty much true for anything, honestly.
This watch celebrates the glory that is the red planet, but it's a standard Earth watch so as not to mess with your head. The Mars Orbit watch has 3-hand movement, with Phobos as the minute hand, Deimos as the hour indicator, and a little rover as the second hand. (At least we think that's how they line up based on which one orbits closer to the planet. The inside one is the minute hand, which should be obvious after a a few minutes.) Does not include life and / or any Earth-shattering kabooms.
