The Aquis Date Caliber 400 41.5mm, Oris’ imminently wearable diver’s watch, returns enriched with a touch of solid gold. The new forest green and deep-blue models both feature an 18-karat gold finish on the outer edge of their unidirectional rotating bezels and gold-colored hands and indexes. Even the minute scale on the ceramic bezel is golden, completing the balanced, coherent look of the design.

Both watches come with either a stainless steel bracelet or a rubber strap in matching green or blue. The straps can be easily switched using Oris’ patented Quick Strap Change system, with no tool required.

All this as well as the brand’s game-changing Caliber 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 Caliber 400 Series watches, the pieces are warrantied for 10 years when registered online.
