Oris Aquis Date Calibre 400 41.5 mm Bi-Colour
Reading Time: 2 minutes

The Oris Aquis Date Calibre 400 41.5 mm, our hugely wearable diver’s watch, returns with two new executions enriched with a touch of solid gold. Both the forest green and deep blue versions have an 18-carat gold finish to the outer edge of their unidirectional rotating bezels, and gold-coloured hands and indexes.

Even the minutes scale on the green or blue ceramic bezel is golden, completing the balanced, coherent look of the design. Both watches come with a stainless steel bracelet and a rubber strap in matching green or blue that can be easily switched using our patented Quick Strap Change system, with no tool required.

All this wraps our game-changing Calibre 400 automatic, which provides the watch with elevated levels of anti-magnetism, a five-day power reserve and 10-year recommended service intervals. As with all Calibre 400 Series watches, both pieces are warrantied for 10 years when registered with MyOris.
