The World on your Wrist

Blancier feels their Worldtimer 1 model is the only mechanical timepiece to accurately display the time in all thirty-nine time zones. This includes those zones that only differ by half hour increments which watchmakers have typically ignored to make things easier.

Blancier uses an extremely accurate 18th century Lambert projection map of the globe which sits behind the watch hands and actually rotates 360 degrees around the hand axis every 24 hours. This time piece was 2 years in the making.
