Oris Aquis Date Calibre 400: The Independent Manufacture Milestone

Real Watches for Real People: Oris's Crowning Achievement

In an era dominated by corporate luxury conglomerates, Hölstein-based Oris remains defiantly independent. When Oris announced the Calibre 400—their first fully in-house developed automatic manufacture calibre in over thirty-five years—they did not simply introduce another movement; they established a new benchmark for everyday mechanical luxury.

Fitted inside the legendary Aquis Date 41.5mm, this timepiece bridges the gap between rugged utilitarian tool and haute-horlogerie engineering.

Three Pillars of Calibre 400

1. 5-Day Power Reserve (120 Hours): Utilizing twin barrels fitted with extended mainsprings, Calibre 400 delivers sustained, stable torque over five full days.
2. Elevated Anti-Magnetism: Over 30 non-ferrous and anti-magnetic components, including a silicon anchor and escape wheel, exceed the stringent ISO 764 anti-magnetic standards by more than 11 times.
3. 10-Year Warranty & Service Intervals: Engineered with a slide bearing system that eliminates traditional ball-bearing wear, Oris provides an unprecedented 10-year warranty upon MyOris registration.

On the Wrist: Dial and Ergonomics

The sunburst gradient blue dial dances under natural Himalayan sunlight. The ceramic bezel clicks with reassuring firmness—precise 120 clicks with zero back-play. The integrated stainless steel bracelet drapes softly over the wrist, equipped with Oris's patented Quick Strap Change system.
