Founded in 1904 in Hölstein, Switzerland, Oris is an independent Swiss watchmaker renowned for its dedication to mechanical watchmaking, technical innovation, and functional design. The Aquis collection represents Oris’s contemporary take on the professional dive watch, combining robust construction with refined aesthetics and advanced in-house movements.
The Oris Aquis Date Calibre 400, reference 01 400 7769 4135, features a 41.5 mm stainless steel case with a deep blue sunray dial, paired with large luminous hands and applied hour markers for excellent underwater legibility. Powered by the in-house Oris Calibre 400 automatic movement, it delivers an impressive 120-hour power reserve, a frequency of 28,800 vph, and enhanced resistance to magnetism thanks to its anti-magnetic architecture. Functions include hours, minutes, central seconds, and a date display positioned at 6 o’clock.
A domed sapphire crystal with anti-reflective coating on both sides ensures superior clarity and scratch resistance, while the unidirectional rotating ceramic bezel adds durability and precise dive timing. With 300 meters of water resistance and a screw-down crown, the Aquis is engineered for professional diving as well as everyday wear. This model is fitted on a stainless steel bracelet with a folding clasp and extension system, offering secure comfort on the wrist.
