Oris Big Crown Propilot X Calibre 115 Watch, 44mm

For the Big Crown ProPilot X Calibre 115, Oris’s watchmakers took the spirit of Calibre 110 and imagined a fully skeletonised Oris movement. Traditionally, skeletonisation provided a window for a watchmaker’s talents, but this movement had higher ambitions. It had to reconnect people to how things work. The Big Crown ProPilot X Calibre 115 lays bare its inner workings. Nothing is hidden. Even the barrel at 12 o’clock is skeletonised so you can see the extended mainspring. Winding the crown, you watch on as the mainspring coils tighter... and tighter... until it’s fully wound and ready to deliver 10 days of uninterrupted power.
