Breva - Genie 02 Terre

In 2013, after three years of research and development, led by Jean-François Mojon, the Breva Génie 01, the world’s first mechanical wristwatch displaying time, altitude, weather forecasting barometric pressure and power reserve. Breva is now presenting the Génie 02 Terre which combines a highly refined mechanical timepiece with a fully functional mechanical altimeter. The Genie 02 is a limited edition of 55 pieces.

Breva Genève was founded by Vincent Dupontreué in 2010, when he was 33. He had the  idea of creating a mechanical timepiece that forecast the weather during a weekend on Lake Como in Northern Italy. The Breva name was suggested by ‘La Breva’, a warm southern wind contributing to the agreeably mild micro-climate around Lake Como.

In 2013, after three years of research and development led by Jean-François Mojon, Breva introduced the Génie 01, the world’s first mechanical wristwatch displaying time, altitude, weather forecasting barometric pressure and power reserve.

Breva is now presenting the Génie 02 Terre which combines a highly refined mechanical timepiece with a fully functional  mechanical altimeter. 

The proprietary movement is visible through the open dial and display back. The dial side is dominated by a sub-dial at 8 o'clock displaying hours and minutes and the precision altimeter sub-dial at 2 o'clock. The altitude scale is available in metric (meters) or imperial (feet) measurements.

Arcing around the top of the dial, the large-scale altitude indicator displays up to 5,000 meters (or 16,400 feet). Below and on a lower level, the small seconds sub dial.

The crown at 4 o'clock allows to open/close the air valve. To calculate the altitude, the valve must be open. Its status is confirmed by the white indicator marked 'sealed' at 4 o'clock. Just below, the 65-hour power reserve indicator. At the bottom of the dial it is possible to see the top of one of the two aneroid capsules which measure the air pressure and, consequently, the altitude. The aneroid capsules in the Génie 02, made from a special non-magnetic memory-metal, were developed specifically for registering air pressure for altitude readings rather than barometric pressure, and are different to those used on the Génie 01.

The crown at 9 o'clock both winds the movement and sets the time while the third crown at 2 o'clock can be used to rotate both the altitude's precision-scale and large-scale to adjust for variations in air pressure, which affect altitude readings. 

The back displays the movement framed by the names of prestigious ski resorts − Aspen, Vail, Las Lenas, Gstaad, St Moritz, Zermatt, Courchevel, Cortina, Kitzbuhel, and Lech − along with their altitudes, engraved around the perimeter of the caseback. When winding the movement you can see the rotation of the cap of the mainspring barrel. 

The Génie 02 is a limited edition of 55 pieces. The dimensions of the titanium G5 case are 44.7 mm x 15.6 mm and it offers water resistance to 30 metres. The retail price is Euro 97,500.
