Oris Big Crown ProPilot X Calibre 115: A Watch for All Time (2019)

The Big Crown ProPilot X Calibre 115 lays bare Oris’s historic watchmaking roots. But at the same time, it propels the independent company forward. It’s pure Oris – as nature intended. 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.
