Clear dial indications

The display is organised in a practical way. The red central hand indicates height in metres on the rotating bezel, which is marked from 0 to 30, that is from 0 to 3,000 metres. As you go higher, it continues to wind around the dial for up to 3 times. At the same time, the subdial at 3 o’clock shows you the height on a smaller scale and can be used to see whether you are in the range from 0 to 3,000m, or from 3,000 to 6,000, or from 6,000 to 9,000. The subdial also shows the air pressure. The neat feature of the watch is the bidirectional rotating bezel with an anodized aluminium insert. As air pressure is not constant, you need to adjust the watch when you are at a known height so that subsequent readings will be accurate. The dial also has a date window at 6 o’clock and a power reserve indicator at 12 o’clock.

30 metres water resistance

The watch is based on a previous model also called the Bivouac, introduced in 1962 and capable of measuring altitudes of up to 3,000 metres. The new version extends the range of altitudes that can be shown. The case has a 3-atmosphere, 30-metre water resistance, achieved by a special covering over the air inlet. It is essential to allow air to penetrate the aneroid chamber, and a micro-perforated water-resistant repelling membrane allows the passage of air but not water or dust.
