Artelier Calibre 113 features a business calendar showing the day, date, week, and month. The day and date are displayed through windows at 12 and 9 o’clock, while the week and month are indicated by a red-tipped central hand, an Oris signature.
Calibre 113 features a hand-wound movement with a 10-day power reserve, exceptional compared to most mechanical watches. This is fueled by a mainspring in an oversized barrel, visible through the sapphire case back. The remaining power is displayed through a non-linear indicator at 3 o'clock.
This unique non-linear power reserve indicator is managed by a ‘worm-gear’, an exclusive Oris development found in Oris’s series of in-house developed calibres. The patented innovation controls the speed at which the power reserve indicator moves around the subdial at 3 o’clock.
