Oris · ProPilot X Calibre 115
The model in detail
Meet the watch
The large barrel draws your eye before the logo. In the ProPilot X Calibre 115, Oris opens the movement on the dial side, making stored energy part of the watch’s appearance. It is a good reason to ask what such a long reserve brings to a skeleton watch beyond the spectacle.
Calibre 115 is manually wound and rated for 240 hours, or ten days. There is no automatic rotor: energy is added through the crown. The benefit in a collection is straightforward. You can put it aside for several days and return without resetting the time, provided energy remains.
On the right is a non-linear power-reserve indicator. The spacing between markings increases towards the end of the scale, making the remaining days easier to judge. That suits a long-running watch: the difference between days nine and ten may matter more to its owner than the difference between days one and two.

This version has a titanium case and bracelet, a diameter of 44 mm and 22 mm lug spacing. The material does not erase those dimensions. Try the bracelet version before buying and check how the broad architecture sits on your wrist. Diameter alone cannot describe the fit.
Small seconds sit around 7:30, while the movement runs at 3 Hz. The watch displays hours and minutes, allows the seconds to be stopped for setting, and carries a 10-bar water-resistance rating. There is no calendar, leaving the focus on mechanical structure and the spaces around it.
The ritual is part of the appeal: wind the watch, read its energy level and watch that level change. Calibre 115 makes sense for this connection between construction and appearance. Ten days is useful, but it does not automatically make the watch more accurate or guarantee a good fit on every wrist.
