Basically, what you see here is one of the most innovative – and coolest too – pilot watches on the market. No, it is not fitted with a super-high-end movement neither it has the most spectacular design ever. The point is not here. Certainly, you already heard about the Oris Big Crown ProPilot Altimeter, a watch we already experienced before. This watch actually is the world’s first automatic mechanical timepiece with a built-in mechanical altimeter. Admit that for a pilot watch, that’s quite an interesting feature. A few days ago, the brand introduced a new version, the Oris Altimeter Rega Limited Edition (resulting from a partnership with Rega, Switzerland’s air rescue service) and what’s better than a proper field-test, in the Swiss Alps, to experience the altimeter function.
