**Oris ProPilot X Calibre 115 | Titanium Skeleton** **Ref. 01 115 7759 7153 | 44mm | Titanium | Full Set | Skeleton Dial**   **Price: $5,840**   The ProPilot X Calibre 115 is a bold architectural statement that redefines the modern pilot’s watch through the lens of industrial transparency. Its fully skeletonized design invites the wearer to explore the mechanical soul of the timepiece, stripping away the traditional dial to reveal a complex landscape of sandblasted bridges and gears. Crafted from lightweight, multi-piece titanium, this watch offers a commanding yet weightless presence, appealing to the collector who prioritizes avant-garde aesthetics and the raw honesty of independent Swiss watchmaking. Beneath the multi-faceted titanium case lies the **In-House Calibre 115**, a manual-wind masterpiece featuring a staggering **10-day (240-hour) power reserve** from a single oversized barrel. This power is monitored by a patented non-linear indicator at 3 o’clock, which tracks the remaining energy with increasing precision as the wind winds down. The integrated titanium bracelet is engineered for superior ergonomics, secured by Oris’s "LIFT" clasp, while the 100-meter water resistance ensures that this high-horology instrument remains remarkably practical for daily wear.
