Description
The Oris ProPilot X Calibre 115, reference 01 115 7759 7153, is a highly technical and modern interpretation of an aviation-inspired luxury watch. It features a 44mm round case crafted from titanium, a material chosen for its strength-to-weight ratio and its ability to keep a large watch comfortable on the wrist. The fixed titanium bezel reinforces the watch’s industrial character, while also helping maintain a clean, purposeful overall design. Paired with a black leather strap, the watch presents a restrained and refined contrast to the advanced materials used in the case, creating a look that feels both contemporary and mechanically focused.
One of the defining characteristics of this model is its fully skeletonized dial, which reveals much of the movement beneath and gives the watch a striking sense of depth and complexity. The openworked construction allows the wearer to see the architecture of the calibre through the front of the watch, while silver-tone hands and hour markers preserve legibility against the intricate background. This design does not rely on decoration for its impact; instead, the visual appeal comes from the exposed mechanics, geometric layout, and the precision of the movement visible through the dial. The result is a watch that emphasizes horological engineering as much as timekeeping.
The protective and structural elements of the watch are equally carefully executed. A scratch-resistant sapphire crystal shields the dial, helping preserve visibility and durability over time. The titanium screw-down crown contributes to the watch’s secure construction and water resistance, while the exhibition case back provides a view of the movement from the rear as well. This combination of front and back transparency gives the watch a full mechanical presence, making it especially appealing to enthusiasts who appreciate movement architecture and visual detail.
At the heart of the ProPilot X Calibre 115 is the Oris Calibre 115, a self-winding automatic movement developed for both performance and display. It offers an impressive power reserve of approximately 240 hours, or ten days, which is one of the most notable features of the watch and a key part of its appeal. That extended reserve reflects the movement’s technical ambition and makes it exceptionally practical for a watch that may not be worn every day. The movement also reinforces the model’s identity as a serious mechanical instrument rather than simply a style piece.
With water resistance rated to 100 meters, the watch is built to handle everyday exposure to water with confidence while still maintaining its refined and architectural design. This level of waterproofing adds practical versatility to a watch that is otherwise visually bold and mechanically complex. Overall, the Oris ProPilot X Calibre 115 is a distinctive modern timepiece that combines titanium construction, skeletonized aesthetics, and an unusually long power reserve into a watch that is both technically impressive and visually memorable.
