Big Crown ProPilot X Calibre 115 : 01 115 7759 7153-SET5 22 04TLC

The Oris Big Crown ProPilot X Calibre 115, reference number 01 115 7759 7153-SET5 22 04TLC, was introduced in 2020 as part of the Big Crown collection. The watch features a 44.0 mm titanium case, giving it both durability and a lightweight feel. Its transparent caseback offers a view into the intricate hand-wound Calibre 115 movement, which is notable for its extensive skeletonisation and impressive engineering. The dial reveals the inner mechanics, including a visible mainspring barrel at the 12 o'clock position, showcasing the watch's exceptional craftsmanship. The Calibre 115 movement provides a remarkable power reserve of up to 10 days, far surpassing the typical two-day reserve found in many mechanical watches. This extended power reserve is managed through a single oversized barrel and displayed via a non-linear indicator at the 3 o'clock position for increased accuracy as winding becomes necessary. The overall style of the watch is modern and technical, appealing to those who appreciate both aesthetics and mechanical excellence in horology.
