Oris has relaunched development and production of in-house mechanical movement for the first time in 35 years with an innovative power reserve complication.
The Oris Calibre 110 will be used in the limited edition Oris 110 Years model to be released next month. Oris executive chairman Ulrich W. Herzog explained to WatchPro that the intention was to gradually increase production numbers in the coming years with further movements being developed.
The Oris Calibre 110, marking the Swiss company’s 110th anniversary, offers a 10 day power reserve with non-linear indicator on the dial. The day indicators are further apart the closer the power reserve gets to a fully depleted state, meaning the hand moves at a faster rate and become more apparent.
The unique movement has been developed between Oris’ own team of watchmakers and designers, Swiss technical specialists and the L’École Téchnique Le Locle over the last ten years.
Each calibre will now be hand-assembled and tested at Oris’s Holstain factory.
The non-linear nature of the indicator is made possible using two ‘shell-shaped’ gears in the patented train, visible through an exhibition caseback on the 43mm watch.
Oris has also opted to use a single barrel with a 1.8metre mainspring rather than the more orthodox twin-barrel method for such a lengthy power reserve.
Since production of in-house movement ceased at Oris in 1982, the company had focused on development of modules and worked with ETA and Sellita on assembly.
The Oris 110 Years Limited Edition will be available in rose gold and stainless steel, with just 110 examples of each being produced.
