The Oris Aquis Date Calibre 400

Luxury Redefined with 18K Gold and In-House Innovation

The Oris Aquis Date Calibre 400 in Steel and 18K Gold is a stunning evolution of the world-renowned Aquis diver’s watch. By blending the rugged durability of high-grade stainless steel with the prestige of solid 18-carat yellow gold, Oris has created a timepiece that is as much a statement of luxury as it is a high-performance tool. This model features a deep forest green sunray dial and a matching ceramic bezel, accented by precious metal to create a color palette that is both timeless and modern.1

The New Standard in Mechanical Excellence

Beyond its striking exterior lies the game-changing Calibre 400, Oris’s independently developed automatic movement.2 This movement was engineered to solve the most common frustrations of watch ownership. With a massive five-day power reserve, you can set the watch down on a Friday evening and pick it up on Wednesday morning without needing to reset the time.3

Furthermore, the Calibre 400 is highly anti-magnetic, featuring over 30 non-ferrous components (including a silicon escape wheel and anchor).4 In a world filled with electronics, this ensures your watch remains accurate despite exposure to the magnetic fields of everyday life.5

Exquisite Craftsmanship and Versatility

The watch’s aesthetic is defined by the 18K yellow gold finish on the outer edge of the unidirectional rotating bezel.6 This gold trim is complemented by gold-plated hands and indices, which are filled with high-grade Super-LumiNova for exceptional legibility in low-light conditions.7

Designed for life on the go, this model features Oris’s patented Quick Strap Change system.8 This allows you to effortlessly switch between the brushed stainless steel bracelet and a professional-grade green rubber strap in seconds, without the need for tools.9 Whether you are dressing for a formal event or preparing for an ocean excursion, this watch adapts to your lifestyle.
