Oris Aviation

The powerhouse at the heart of most Oris watches is the automatic calibre 733. This calibre, based on the Sellita SW200-1, drives popular watches within collections such as Aquis, Artelier, Big Crown, and more. The Oris 733 powers the central hands and a date function. This 4.6mm thick mechanism boasts a decent reserve of 38 hours and beats at a frequency of 28,800 vibrations per hour. The smooth functioning of the movement is ensured by 26 strategically placed jewels.
