It’s hard to believe that in 2016 Oris was the only the second watchmaker to offer a mechanical altimeter in a wrist watch. The first was a Breva model costing over $100,000, while the Oris, in characteristic form, retails for $3,800. Cutting-edge materials like carbon fiber and specialized alloys have allowed for the miniaturization of the highly sensitive internal barometer mechanism, which also manifests itself in the form of an altimeter by scaling its tiny fluctuations onto a legible calibrated scale around the dial. The scale on the Oris Altimeter I tested was in feet, though it is also available in meters.
