Come rain or shine, the Breva Génie 01 is the world’s first wristwatch that can forecast the weather debuted at Baselworld in 2013. A fully mechanical marvel expressed in an openworked design, the dial reveals a wealth of information to inform its wearer of not only the time, but the altitude, power reserve, and barometer (instrument for measuring air pressure). Sized at a massive 44.7mm diameter, a total of 110 pieces were produced for the Génie 01 with 55 pieces each in white and pink gold like the present example.

A heck of a complicated watch, this beast is animated by the proprietary movement developed exclusively for Breva by Jean-Francois Mojon and Chronode. A total of 405 components featuring a dual aneroid capsules measuring air pressure and a spiral anti-vibration spring gives this movement a total of 65 hours of power reserve.

A complicated timepiece operated with a user-friendly approach in mind, the functions can be operated by three dual-purpose crowns. Setting time and winding the watch (anti-clockwise) can simply be accessed via the crown at 9 o’ clock. The barometric pressure scale can be adjusted by the knurled ring, while the pusher allows you to adjust the position of the altitude indication positioned from 9 to 12 o’clock near the edge of the dial. The remaining crown allows the wearer to lock or unlock an air valve to equalize the air pressure. A red indicator marked SEALED on the dial warns the wearer when the valve is unlocked.

More than telling time and definitely a fun and impressive timepiece, the present example in pink gold is numbered 18 from the limited edition and is accompanied by its full set of accessories including a large aneroid barometer presentation box.
