The Aquis Date Calibre 400 41.5 mm, Oris' 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 uni directional 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 the brand's patented Quick Strap Change system, with no tool required. All this wraps the game-changing Calibre 400 automatic, which provide s 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.
