The skeletonised Calibre 115 movement opens up the 10-day power reserve and non-linear power reserve indicator to reveal how they work.

This movement combines a 10-day power reserve, Oris’s patented non-linear power reserve indicator, a date indication and, for the first time, a 24-hour second time zone with half-hour indication. No other mechanical watch in Swiss watchmaking combines these functions in a single watch.

Calibre 113 shares the same base architecture as Oris Calibres 110, 111 and 112, but features a novel business calendar, showing the day, date, week and month of the year.

Oris Calibre 112 is a hand-wound calibre that features a 10-day power reserve, a patented non-linear power reserve indicator, a date function, and a second time zone with day/night indication.

Oris Calibre 111, a hand-wound calibre that features a 10-day power reserve, a patented non-linear power reserve indication and a date function.

Oris Calibre 110 was developed in-house and produced in partnership with Swiss specialists. It has a pure, industrial look, in keeping with Oris’s watchmaking philosophy.
