A TRUE WEATHER STATION ON YOUR WRIST

Breva Génie 01

The Breva - Génie 01 is the world’s first wristwatch with time, altimeter, barometer (for forecasting the weather) and power reserve indications provided by a fully mechanical movement, much of which is on display through the open dial and display back. The proprietary movement of the Génie 01 was developed exclusively for Breva by Jean-François Mojon (Chronode).

A dial side tour reveals a plethora of easy-to-read indications to keep the wearer fully informed about current time, altitude, remaining power in the mainspring, and a weather forecasting barometer.

Breva Génie 01

Hours and minutes are displayed on a semi-transparent smoky-sapphire sub dial at 8 o’clock, with small seconds below 12 o’clock. A scale displaying altitude arcs around the top perimeter of the dial. Barometric pressure is indicated on a second semi-transparent smoky-sapphire sub dial at 2 o’clock, with icons providing scientifically based forecasts of likely weather conditions to come.

A 65-hour power reserve indicator at 4 o’clock is instantly recognizable thanks to its engraved compass rose, an icon found throughout Génie 01. At 6 o’clock, an anaerobic capsule measuring air pressure dominates the lower section, with another identical anaerobic capsule underneath it to maximize sensitivity to the slightest change in air pressure.

Three dual-purpose crowns on the case band provide power to, and allow setting of, the proprietary Breva movement. On the left at 9 o’clock, a two-position crown is dedicated to winding the watch and setting the time. On the top right at 2 o’clock, a knurled exterior ring adjusts the barometric pressure scale, while an inner pusher adjusts the position of the altitude indication.

At 4 o’clock, a second crown on the right has a knurled locking ring that rotates 90° to lock/unlock an air valve. When unlocked, the valve opens and allows a small amount of air to equalize air pressure inside the case with the exterior air pressure. Longevity and reliability of the timepiece are maximized by means of an osmotic Teflon membrane that filters any moisture from any air before it enters the movement. Just above the crown, a red indicator on the dial marked "SEALED" warns when the valve is unlocked.

Breva Génie 01

The technological and visual feast continues through to the back of Génie 01. A circular scale engraved around the perimeter of the casebackprovides a scale providing correlations between altitude and air pressure, as the altitude affects air pressure as well as the weather.

Through the sapphire crystal display back, it is the vibrantly oscillating balance wheel that first catches the eye; however a more carefully inspection unveils yet more of the beautifully finished movement. When winding the movement you can see compass roses rotating on the cap of the mainspring barrel.

Breva Génie 01

The name "Breva" is inspired by "La Breva", a warm southern wind that contributes to the agreeably mild microclimate around Lake Como in northern Italy. Breva Watches breathes a refreshing breeze through the often-stuffy world of Swiss haute horlogerie.

There are two case versions of this model:

THE ANAEROBIC BAROMETER AND ALTIMETER IN THE GÉNIE 01

A barometer is an instrument for measuring air pressure, first invented by Evangelista Toricelli, a pupil of Galileo, in 1643. There are two main types of barometer: a mercury barometer, in which the pressure of the air forces a small column of mercury up a tube (similar to a mercury thermometer); and the anaerobic barometer, in which one or more aneroid capsules (aneroid means "without air") expand/contract with changing air pressure.

Breva Génie 01

The barometer and altimeter (air pressure changes with both altitude and weather conditions) measure air pressure with two small aneroid capsules stacked one above the other, the top one being clearly visible on the dial side at 5 o’clock.

The aneroid capsules in the Génie 01 were especially developed to Breva's specifications to optimise their precision and use in a wristwatch. The capsules are made from a special non-magnetic memory-metal (Breva patented invention), which is lighter and stronger than aluminium and has twice the ductility of steel. The capsules are exposed for long durations to high temperature and pure oxygen to maximise thermal conductivity and oxidation resistance.

Breva Génie 01

A clearly visible lever rests on top of the aneroid capsules and transmits the combined height of the capsules through a complex system of gears and racks to the altimeter indication and the barometer. The gearing for these two displays has been carefully calculated as the scale of changing air pressure due to altitude variations is quite different to weather variations.

The attitude display reads from -300 to +5,300 metres, while the barometric display ranges between 973 and 1053hectopascals (hPa). In a nod to the original method of measuring air pressure in inches of Mercury, an inner scale of the barometer is marked mmHg: Hg being the atomic name for Mercury (Hg from the Greek hydrargyrum meaning "silver water").

THE BAROMETER

Before using or adjusting the barometer, air pressure inside the movement should be equalised with the exterior air pressure using the valve at 4 o’clock.

Breva Génie 01

What is important in using air pressure to forecast the weather is the recent change in pressure, rather than the pressure itself. Rising pressure indicates good weather coming, falling pressure is a sign of inclement weather ahead. The faster the pressure changes and/or the larger the change, the more extreme (good or bad) the coming weather is likely to be.

After equalising the interior air pressure, the barometer dial is rotated so that the hand points through the centre of "météo" (French for weather forecast) to 1013 hPa, which is the standard (not necessarily actual) air pressure at sea level. Over the next hours, assuming no change in altitude, the hand might remain in place, indicating no change; move toward lower pressure, suggesting a possible deterioration in the weather; or move towards higher pressure, suggesting sunny weather coming on its way. Slow/small movement suggests minor changes, while fast and/or large movement forecasts more extreme weather ahead.

THE ALTIMETER

Before using or adjusting the 5,300m/17,000' altimeter, air pressure inside the movement should be equalised with the exterior air pressure valveat 4 o’clock.

Breva Génie 01

Because air pressure can vary throughout the day (due to weather changes) the altimeter should be regularly set at a known altitude to ensure accurate results. As the hand is directly linked to the air pressure, the pusher at 2 o’clock moves the altitude dial (rather than the hand) left or right to synchronise the correct altitude with the indicator hand.
