The major difference between the new 02 Air and last year’s model is that the original’s barometric “weather forecast” indicator at 2 o’clock has been replaced with a large, fine-scale altimeter. The hours and minutes are still displayed on the other large subdial located at 8 o’clock.
Arcing around the top of the main display is the large-scale altitude indicator, which displays up to 5,000 meters (or 16,400 feet). The small seconds indication appears below that, at 12 o’clock. To measure altitude, the air valve must be open, and an indicator at 4 o’clock tells you whether the valve is open or closed. Below that is the 65-hour power reserve indicator.
The altitude indicators are driven by two aneroid capsules that measure air pressure. One of these can be seen in the background at the bottom of the dial. A high-precision arm multiplies the capsules’ expansion and contraction by a factor of 200 to generate the correct altitude indications.
Three engraved crowns wind, set, adjust, and operate the functions of the Génie 02. A two-position crown at 9 o’clock winds the movement and sets the time. The crown at 2 o’clock rotates the precision and large-scale altitude indications to adjust for variations in air pressure, which affects the readings. The screw-down crown at 4 o’clock either seals air out of the movement or allows it in for altitude function. An osmotic Teflon membrane filters moisture from air before it enters the movement, increasing longevity.
The Génie 02 Air is a limited edition of 55 pieces in grade 5 titanium and is available with calibrations in either meters or feet. The retail price is $132,000. Complete technical details appear below.
On Friday morning we met with Breva. Here are some live images of the Génie 02 Air in titanium with black DLC (top), in titanium (center), and the movement (bottom)…
