ProPilot Calibre 115

The Oris ProPilot Calibre 115 stands out for its in-house, hand-wound movement with a remarkable 10-day power reserve, visible through an openworked dial that showcases the intricate mechanics. Introduced as a flagship in the ProPilot lineup, this model is a statement piece for those who appreciate technical innovation and aviation-inspired design. Its skeletonized construction and oversized 44mm case make it both visually striking and a conversation starter among collectors who value independent Swiss watchmaking.

The key reference for this model is the 01 115 7759 7153-Set7 22 01TLC, featuring a titanium case and textile strap, though variations exist with different strap options. Price differences are usually driven by the condition of the movement, completeness of the set (box, papers, original strap), and any limited edition packaging. The Calibre 115 movement itself is a major value driver, as it is exclusive to this series and offers a non-linear power reserve indicator—an uncommon feature at this price point.

When considering a ProPilot Calibre 115, check for smooth operation of the power reserve indicator and inspect the openworked dial for any signs of mishandling, as the skeletonized structure is more susceptible to visible scratches or dust. Water resistance is rated at 100 meters, making it versatile for daily wear, but the real appeal lies in its horological engineering and distinctive presence on the wrist. This is a watch for those seeking a modern, technically advanced Oris with genuine collector cachet.
