The UNDONE Space Xplorer watch is now officially sold out. Inspired by SpaceX‘s Dragon V2, only 300 pieces were produced. The mission marked the first time a private company sent NASA astronauts (Bob Behnken and Doug Hurley) to the International Space Station. Just like the spacesuits worn during the historic test flight, UNDONE hermetically sealed the Space Xplorer watch and shaped it to mimic astronaut collars. The chapter ring represents a top-down view of the V2 reusable spacecraft. The watch glows at night and is waterproof up to 50 meters. The back of Space Xplorer is inscribed with “Of Course I Still Love You,”—the SpaceX drone ship named after one of the vessels in the sci-fi Culture series by Iain Banks (Elon Musk is a huge fan). Like Space tourism and innovation itself, UNDONE’s intent was to push the limits of human imagination. On planet Earth, you never know when the next Space Xplorer edition will drop, so stay ready.
