Oris Big Crown ProPilot

Calibre 115 01 7759 Crown Propilot Aviation Big 22  Calibre 115 is a hand-wound movement operated through the watch’s single crown. When fully wound, the movement will deliver 10 days of power – most mechanical watches run for around two days. This exceptional, 240-hour power reserve is fuelled by a mainspring coiled in a single oversized barrel, visible at 12 o’clock. The power reserve is displayed through an Oris-developed and patented non-linear power reserve indicator at 3 o’clock that shows the power remaining with ever greater accuracy as the time to wind the watch approaches.
The Oris Big Crown ProPilot X Calibre 115 is powered by a skeletonised, in-house developed calibre with a 10-day power reserve and an Oris-patented non-linear power reserve indicator that shows the power remaining with greater accuracy as the time to rewind the watch approaches. The watch comes with a special luxury wooden presentation box and an official manual. box and papers
