All of these characteristics are highly beneficial in watchmaking. This glass-like material is not liable to corrosion and is temperature stable, friction-free and anti-magnetic. Oris has equipped its new movement with a silicium escape wheel and pallet lever. The watch is equipped with a unidirectional oscillating weight which, according to the brand, is simpler than a bi-directional rotor and thereby less likely to malfunction. This movement is equipped with two barrels, delivering 5 days of autonomous operation.

Now the Swiss marque has unveiled a new movement, the Calibre 400.

Released to mark the firm’s 110 year anniversary, it was the company’s first in-house movement for 35 years. This movement is hand-wound and boasts a prodigious power reserve of 10 days courtesy of one barrel. Historically, Oris has sourced movements from ETA or Sellita, however, in 2014, the brand from Hölstein released the in-house Calibre 110. The cost of developing and making a movement is huge and requires much know-how, barriers which prevent many watch brands taking the in-house route. Most watch brands procure movements from specialist companies such as Chronode, Concepto, ETA, La Joux-Perret, Sellita, Soprod, Vaucher et al. Lastly, the Swiss marque provides peace of mind, courtesy of an impressive 10-year warranty. The brand state servicing is only required every 10 years.

Two barrels collaborate to deliver a 5-day power reserve, the rotor has been designed to enhance reliability and the presence of silicium components mitigates the risk of magnetic influence on the escapement. The Oris Aquis Date Calibre 400 is a new divers’ watch equipped with the brand’s latest in-house movement, the Calibre 400.
