The cases of the Oris Aquis Calibre 400 Bicolour watches remain faithful to their dive-worthy predecessors with a screw down crown protected by screwed guards and a a screw down mineral glass exhibition case back ensuring a 300 metre water resistance.

Now offering more metal options in this diameter is the new range of Oris Aquis Calibre 400 Bicolour watches dressed in stainless steel and 18ct gold. One of the best-selling designs however is the Oris Aquis Calibre 400 41.5mm which calls to those with a preference for smaller watches with its reduced case size. Over the last 24 months, we’ve seen the movement extend across the brand’s vast portfolio including within an Oris AquisPro watch and more recently a series of Oris ProPilot X watches. First launched in 2020, the Calibre 400 movement debuted with a duo of 43.5mm Aquis watches offering the legendary divers aesthetic with ceramic bezels, 300 metre water resistant cases and a nautical blue dial. The Oris Calibre 400 movement series has been the Swiss watch manufacturer’s greatest innovation of the last two years.
