Big Crown ProPilot Altimeter : 01 733 7705 4134-SET 8 23 19

The Oris Big Crown ProPilot Altimeter Feet, reference number 01 733 7705 4134-SET 8 23 19, was introduced at Baselworld in 2014. This model is notable for its integrated Swiss mechanical barometric altimeter and barometer movement, a feature developed in collaboration with Thommen. The watch is powered by the Oris caliber 733, which is based on the Sellita SW200 automatic movement. Its case, made of steel, has a solid caseback and measures a substantial 47.0 mm in diameter. The black dial features alternating Arabic numerals and stick indexes for clear readability. A black textile strap complements the rugged yet sophisticated appearance of this timepiece. One of its standout features is the real-time altitude change display, made possible by an aneroid capsule system that measures air pressure to determine altitude.
