Story & Heritage

The introduction of Calibre 400 marks one of the most important chapters in Oris’s modern history. Staying true to its independent spirit, Oris developed a completely new in-house movement designed for real-world use—offering longer service intervals, superior resistance to magnetism, and exceptional long-term reliability.

The Aquis Date Calibre 400 embodies this philosophy perfectly. More than a certified professional dive watch, it is a modern mechanical instrument built to withstand everyday challenges while delivering outstanding performance. Its advanced antimagnetic properties protect the movement from one of the most common causes of inaccuracy in modern watches, while its solid construction reflects Oris’s commitment to practical, honest engineering.

For collectors and enthusiasts, this model represents the beginning of a new era for Oris—an era defined by innovation, independence, and functionality without compromise. A watch that does not follow trends, but confidently sets its own standards.
