Big Crown ProPilot X Calibre 115

This New Pilots Watch Is a Game-Changer For Oris


September 5, 2019 Watches By

Longtime pilots watch manufacturer Oris has released a new timepiece, the Big Crown ProPilot X Calibre 115, that makes use of a unique, completely skeletonzied movement, the development for which took two years. Based on the calibre 110, which was developed for Oris’s 110th anniversary, the hand-wound cal. 115 features an impressive 10-day power reserve, a non-linear power reserve indicator and a small-seconds display.

Designed completely in-house by the Oris team, the movement is devoid of varnish or any decoration, and entirely skeletonized — even the barrel — so that the user can see and understand how the movement works. There are no chamfers or bevels, and even the movement’s bridges are matte grey. This is intentional on Oris’ part, and meant to drive the user’s focus to the watchmaking on display.

The cal. 115 is housed in a 44mm titanium case that features a jet engine turbine blade motif along the bezel. The watch also features a matching 22mm lug-width titanium bracelet with a “lift” clasp, or a black leather strap with a similar clasp. It’s water-resistant to 100m and is available immediately, priced at $7,600 on the titanium bracelet or $7,200 on the leather strap.
