Despite being over fifty, space exploration remains mind blowingly cool. Lance Bass notwithstanding, the title of Astronaut (née Cosmonaut) holds strong its position as the ultimate trump card when it comes to professions. It should come as no surprise then that we, ahem, gravitate to timepieces that can journey beyond our world. A space watch is more than just branding. Torture tested to excel in the most inhospitable of environments, these timepieces are designed to survive instantaneous 200 degree shifts in temperature, acidic humidity and extreme g-forces (shocks up to 40 Gs). Much like the explorers who don them, there are but a lucky few that have earned special recognition. These are our eight picks of the best space watches (or their modern reinterpretation) available for the rest of you dreamers out there.
