Oris 110

The Oris Calibre 110 is a manual-winding in-house movement launched in 2014 to mark the brand's 110th anniversary—it was Oris's first in-house caliber in nearly 40 years. The movement features a 10-day (240-hour) power reserve delivered through a twin-barrel design, with 34 jewels throughout the going train. Its defining characteristic is a patented non-linear power reserve indicator that provides a more accurate reading of remaining runtime as energy depletes. The Calibre 110 remains in production and serves as the base for several Oris anniversary and dress watches.
