Adept in fine watchmaking, Oris announces their latest offering, a unique update of the Aquis Date Calibre 400 in a smaller 41.5mm.

Following the birthday of the eponymous Swiss matchmakers last month, Oris proves that the joy of mechanics remains as ever present since their inception in 1904. In a digitally driven world where we’re connected by touch, the role of mechanics has taken on an entirely new meaning. Driven by this curiosity, while the traditional artisans make peace with the notion that mechanical watches are not so much a necessity anymore, they pride themselves on the knowledge that for those that do, a simple pleasure comes from its effectiveness to tell time accurately.

Maintaining the momentum of intricate artform, the new Oris Calibre 400 41.5mm brings joy to the surface, setting a new standard in automatic mechanical watchmaking. Created in-house by independently skilled craftsmen, it offers elevated levels of anti- magnetism and a five-day power reserve, and comes with a 10-year warranty and 10-year recommended service intervals, exuding durability.

Twin barrel concepts allows time for change 

In the conceptualising process, Oris’ engineers discovered that in the present day, the desire to wear the same watch every day has faded. Usually, that means putting down your watch for a day or two will stop resulting in a run-down power reserve. In response to this, the Calibre 400 Series movements have a five-day power reserve. They deliver this longer period of use via twin barrels, both of which house an extended mainspring, each long enough to store two-and-a-half days of power.

Maintaining authority in everyday life

When exposed to the manifold magnetic objects we face in everyday life, most Swiss watch movements will be magnetised by result, making for a less accurate recording of time or stopping altogether.  To make it highly anti-magnetic, Oris engineered the Calibre 400 Series using more than 30 non-ferrous and anti-magnetic components, including a silicon escape wheel and a silicon anchor. 

In testing by the renowned Laboratoire Dubois, Calibre 400 deviated by less than 10 seconds a day after exposure to 2,250 gauss. For context, the latest version of the ISO 764 standard for anti-magnetic watches requires that to qualify as anti-magnetic, a watch must be accurate to within 30 seconds a day after exposure to 200 gauss. Calibre 400 recorded one third of the deviation allowed after exposure to more than 11 times the force permitted, making it a highly anti-magnetic movement.
