Flying higher, while sitting slimmer and lighter on the wrist, Oris has upgraded its ProPilot Altimeter — a simple, yet high-functioning practical wristwatch tool packed with technical innovation, which remains the world’s first and only automatic mechanical watch with a mechanical altimeter. Since the brand's inception, Oris has developed more than 280 unique calibres and countless watches, many of them offering pioneering, useful, easy-to-use complications. The ProPilot Altimeter continued that tradition by accurately relaying the time, air pressure and altitude via a single dial – entirely mechanically. Full of innovation, it became a watch that pilots & mountaineers alike could depend upon. And after a three-year project, Oris has made this unique tool watch even better. The new ProPilot Altimeter has an improved altimeter module, capable of indicating altitude up to 19,700 feet or 6,000 meters — a 25% increase over the previous generation.
