The Omega Speedmaster Skywalker X-33 uses ESA's patent based on ideas from ESA astronaut Jean-François Clervoy that helps astronauts track their mission events.
One of the new functions allows the wearer to set a date in the past or future down to the second and have the watch calculate how much time has elapsed or is left.
Other features useful for astronauts include flexible programming of multiple alarms with different ring tones.
The Skywalker passed rigorous testing at ESA’s technical heart, ESTEC, in Noordwijk, the Netherlands, where many ESA satellites are put through their paces before launch.
