FAVRE-LEUBA, STAINLESS STEEL 'BIVOUAC' ALTIMETER, REF. 53203

The Bivouac in particular was the choice of Frenchman Paul-Émile Victor on his polar expeditions to Antarctica. The watch actually solved an issue he encountered on his ascent. Pocket altimeters, the best alternative at the time, were extremely difficult to read and handle at high altitudes, especially in icy conditions – so having the function readable at a glance was immensely useful.
