Oris Aquis

The Birth and Evolution of Modern Dive Watch Design

Oris brought its underwater heritage, dating back to the 1960s, into a modern line with the Full Steel of the 1990s and the TT1 series that emerged in the early 2000s. Introduced in 2011, the Oris Aquis embodied the brand's technical expertise as an independent and contemporary dive watch collection. Unlike the Divers Sixty-Five series, which focuses on classic vintage details, the Aquis gained a tool watch identity focused directly on functionality with its angular case lines, high-pressure resistant body, and industrial stance.

With its second-generation update in 2017, the collection gained a profile that can be worn both underwater and as an everyday watch with a suit, thanks to slimmer lugs and a refined case form. The third generation introduced in 2024 reinforced the modern line of the series with a thinned case thickness, renewed indices, and optimized bracelet ergonomics.

Case Architecture, Material Quality, and Movement Choices

The Oris Aquis offers a wide range of case diameter options, such as 36.5 mm, 39.5 mm, 41.5 mm, and 43.5 mm. One of the most defining design elements of the model is its integrated bracelet structure connected to the case with special screws and a unidirectional rotating ceramic bezel insert. Screw-down crown guards and a water resistance rating up to 300 meters complete the technical standards of the model. References like the 01 733 7766 4150-SET, produced from recycled PET plastic and exhibiting a unique pattern on every dial, bring the eco-focused vision of the Aquis series to the collection.

There are two main paths on the movement side: the Oris 733 automatic movement with a red rotor based on a proven Sellita base, and Calibre 400, an in-house manufacture caliber developed by the brand itself. Providing a five-day power reserve and high anti-magnetic resistance, Calibre 400 elevates the technical bar of the model to the top tier.

Things to Consider When Inspecting a Pre-Owned Oris Aquis

When evaluating a pre-owned Oris Aquis, you should pay attention to whether the case retains the shape of its brushed and polished surface transitions. Because the integrated lugs are connected with special screws, screwdriver marks in the screw recesses and connection gaps on the bracelet must be inspected. The absence of marks on the sapphire crystal with double-sided anti-reflective coating and the clarity of the ceramic bezel give an accurate idea of the watch's condition. Furthermore, having a full set with box and papers makes tracking service history easier.
