In 2017, Favre-Leuba unveiled Raider Bivouac 9000, the first mechanical wristwatch capable of measuring altitudes of up to 9,000 m above sea level. In 2019, the Raider Bivouac 9000 delights its fans with a new version dressed in stylish black. It is also available with a lifesaving RECCO® reflector strap.
When Japanese mountaineer Junko Tabei became the first woman to reach the summit of Mount Everest on May 16, 1975, she was wearing the world’s first mechanical wristwatch capable of measuring air pressure and altitudes of up to 3,000 m above sea level via an aneroid barometer. Favre-Leuba developed this revolutionary instrument watch 12 years earlier. Christened Bivouac, the piece set new standards in the art of watchmaking and quickly became an essential companion for mountain climbers, pilots, explorers, and outstanding pioneers.
Launched in 2017, on the occasion of Favre-Leuba’s 280th anniversary, the Raider Bivouac 9000, which can accurately display altitudes of up to 9,000 m, pays respectful tribute to its legendary role model, Bivouac.
Since its launch, the Raider Bivouac 9000 has participated in countless expeditions and adventures across the globe as a reliable companion even under extreme conditions.
Aesthetically, the Bivouac 9000 has a unique contemporary style. Its impressive case, made of lightweight, hard-wearing, and hypoallergenic titanium, is enough to make this watch stand out from the crowd. With a diameter of 48 mm, it provides the perfect backdrop for the dial. The main design priority was optimal readability under all conditions, and this is now even clearer with the new deep black version.
Against the black background, the applied indexes and the striking hour and minute hands, which are white in daylight and glow in the dark, cannot be missed. The subdials for the altimeter and the air-pressure display at 3 o’clock, for the small-seconds dial at 9 o’clock, and for the power reserve indications at 12 o’clock are sharp black with clean white hands. These simple colors draw the eye to the deep red central hand, which with the scale on the bidirectional rotating bezel indicates a climb in altitude of up to 3,000 m per rotation. Meanwhile, the small red hand on the subdial at 3 o’clock indicates altitude gain in steps of 1,000 m, up to a maximum of 9,000 m.
The principle of measuring altitude and air pressure using an aneroid barometer was a feature of the 1962 Bivouac and remained unchanged for the new version of the black dial Bivouac 9000. It uses this barometer to record changes in altitude and air pressure as they occur during ascents, descents, and changes in weather. For the new model, the designers chose innovative materials and made very precise calculations for the barometer capsule design, so that the Bivouac 9000 can now display altitudes of up to 9,000 m above sea level.
A power-reserve indicator also gives the wearer plenty of warning when the watch needs to be wound after the movement has been running for over 60 hours. The mechanism behind this display is also far from standard: its design is so ingenious that it can perform its complex task with as few components as possible, making it even more reliable. Last but not least, the Bivouac 9000 is water-resistant, unlike its 1962 counterpart.
The watch is also available with Kevlar strap with an integrated RECCO® reflector that can help save lives. RECCO® technology was developed to search for missing or buried avalanche victims and is used by mountain rescue teams across the globe. The reflectors, which operate without a separate power supply, are located by search devices and are therefore a useful addition to avalanche transceivers.
