Voyager: the World-Time Wristwatch
A concept watch that uses a physical interface to display time from around the world (2014)
What is this?
'Voyager' is a wristwatch concept that uses a physical interface to simultaneously display time from 24 different time zones, while also being able to adjust to daylight saving changes in all of them. This means that regardless of which timezone you are in, or even if traveling across multiple ones, you always know what time it is everywhere in the world.
