Breva Genie 01: The Weather Watch

A standout recently at Geneva’s prestigious SIHH watch show, the Breva Génie 01 is the world’s first mechanical weather station worn on your wrist, using tiny aneroid capsules made of a patented non-magnetic memory metal, for both a barometer and an altimeter.

One winding lasts 65 hours—useful when you’re stuck atop the Alps without cellphone reception. Breva is selling just 55 of them, for $170,000 apiece.
