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.
