The 2015 Oris Big Crown ProPilot (ref. 01 111 7711 4163-Set 5 22 14FC) is powered by the new Caliber 111 hand-wound movement. Developed and built on their own premises, the beautiful mechanism not only makes this new timekeeper even more exclusive but also shows that Oris has enough resources to design and put on the production line a wonderful caliber. Their new Cal. 111 is an in-house mechanism that, at least in terms of functionality and efficiency, rivals those recently introduced by a lot more established watchmaking houses.
