The Oris Aquis Date Calibre 400 is the 43.50mm version of the Swiss brand's flagship dive watch fitted with Calibre 400, Oris's own in-house movement with a five-day power reserve and everyday anti-magnetic resistance. This reference runs a blue dial on a steel bracelet, rated to 30 bar (300m). Cazador has no verified price observations yet for this reference.

History

Oris was founded in 1904 in Hölstein, Switzerland, and remains one of the few mid-sized Swiss manufactures that is still fully independent, belonging to no larger watch group. The Aquis family is its professional dive-watch line, rated to as much as 300 meters with a unidirectional bezel, built to compete with benchmark divers from larger brands while staying more accessibly priced.

The line's biggest technical leap arrived with Calibre 400, the first automatic movement designed and produced entirely by Oris after decades of relying on supplier bases such as ETA or Sellita. Calibre 400 introduces a power reserve of up to 120 hours — five days, well above the usual two or three days in the segment — thanks to a twin-barrel architecture, along with anti-magnetic resistance built for everyday exposure to smartphones, speakers, and other devices with magnets.

This specific Aquis Date Calibre 400 reference pairs the 43.50mm multi-piece steel case with a ceramic bezel minutes-scale insert, a blue dial, and a steel bracelet with a security folding clasp and extension, designed to fit over a wetsuit. The case back isn't transparent on the standard Calibre 400 versions, since Oris prioritizes robustness and watertight sealing over showing off the movement's finishing in this caliber.

Oris recommends a service interval of up to 10 years for Calibre 400, double the usual interval in Swiss mechanical watchmaking, and extends the standard 2-year warranty to 10 years if the owner registers the watch through the MyOris program. This is the fifth Oris reference in Cazador's catalog and the first fitted with the in-house Calibre 400.

Is the Aquis Date Calibre 400 dive-rated?
