The Raider Bivouac 9000 is built for those who bear a desire to explore higher. The alpine tool watch is engineered with an in-built barometer. As the climber ascends the mountain, the lowering air-pressure is recognised by the watch. In turn, an altitude dial on the face of the Bivouac begins to rotate. Allowing the wearer to gauge their altitude throughout the ascent.
Hand-wound FL311 movement based on the EMC 3903M caliber, specially designed mechanisms for altimeter and power-reserve indicator, power reserve of 65 hours.
Hours, minutes, small seconds, central hand to display altitudes of 3,000 m per full rotation, subdial for displaying altitudes of up to 9,000 m and air pressure in hPa, power-reserve indicator, date display
Gray antelope leather

Furthermore, fluctuations in air-pressure can signal a new weather system could be approaching and the time to consider your next move is upon you. Assessing the length of time to reach your current altitude, distance from summit and safe-zones. As well as remaining day-light is also indicated on the dial of our Bivouac 9000.
