The Oris Aquis Date Calibre 400 01 400 7763 4135 is a modern Swiss dive watch that showcases Oris’ commitment to independent watchmaking. Featuring a 43.5 mm stainless steel case, a blue sunburst dial, a scratch-resistant blue ceramic bezel, and 300 meters of water resistance, it is built for both professional diving and everyday wear. The integrated stainless steel bracelet, sapphire crystal, and exhibition caseback give the watch a refined yet sporty appearance, while its clean design and exceptional legibility have made it one of the brand’s most recognizable models.

Its defining feature is the in-house Oris Calibre 400, an automatic movement developed to prioritize reliability and long-term ownership. It offers an impressive 120-hour (5-day) power reserve, outstanding anti-magnetic resistance, a recommended 10-year service interval, and a 10-year warranty when registered with MyOris. As one of the first Aquis models to feature the Calibre 400 and now discontinued following the 2024 redesign, this reference has become increasingly desirable among enthusiasts. It remains one of the best values in the luxury dive watch segment, combining cutting-edge movement technology with robust build quality at a price that undercuts many of its Swiss competitors.
