ProPilot Altimeter

The Oris ProPilot Altimeter broke new ground as the world’s first automatic mechanical watch with a built-in mechanical altimeter, making it a standout for aviation enthusiasts and adventure seekers. Originally launched in 2014, it quickly earned a following for combining traditional Swiss watchmaking with a genuinely practical complication rarely seen in wristwatches. Its large 47mm case isn’t just for show — it houses both the automatic movement and a fully functional, air-pressure-driven altimeter, a feature that sets it apart from other pilot’s watches.

Reference numbers like 01 733 7705 4134 (meters scale) and 01 733 7705 4164 (feet scale) denote the two main variants; the choice between metric and imperial scales affects both collectability and usability, depending on your preference or intended market. Condition and completeness (box, papers, original strap) drive price variation, but so does the clarity of the altimeter’s function — look for examples where the altimeter hand resets accurately and the crown mechanism for the altimeter remains airtight. The movement inside is the dependable Oris Caliber 733, based on the Sellita SW200, which keeps service straightforward and parts accessible.

Water resistance is rated at 100 meters, notable given the additional crown and case complexity introduced by the altimeter system. The case is stainless steel with a knurled bezel, and the dial is designed for maximum legibility, with a dedicated scale for altitude readings. When considering a ProPilot Altimeter, prioritize examples with a tight case seal and smooth altimeter operation, as these are crucial for both accuracy and long-term durability of this unique complication.
