About the Oris Aquis Collection
The Oris Aquis line, launched in 2011, remains one of the most captivating and eye-catching models of the company's dive watches. This collection's history can be traced back to the beginning of Oris' commitment to creating tool watches for divers in 1965. The Aquis series builds upon earlier models like the TT1 and ProDiver, incorporating advanced features and designs tailored for underwater exploration. Notably, the Aquis marked Oris' first integration of the in-house calibre 400 in 2020, a significant milestone in the brand's evolution.
Sleek And Functional Design
The Aquis collection is renowned for its robust and sporty aesthetic. Featuring a water-resistant case, typically in stainless steel, the watches showcase a unidirectional dive-scale bezel and a domed sapphire crystal. The design includes sculpted lugs, enhanced crown protectors, and steel bracelets with Quick Adjust clasps. The dials feature polished, shield-shaped hour markers and new Alpha-shaped hands, which enhance style and functionality.
Cutting-Edge Features
Features of the Aquis collection emphasise durability and functionality. Movement options include the Oris calibre 733 and 774, known for their precision and reliability. Recent innovations like the Aquis Date Calibre 400 highlight Oris' advancements with a five-day power reserve and enhanced anti-magnetic properties, setting a new benchmark in mechanical watchmaking. Whether opting for the Aquis Date or limited editions like the Aquis Sun Wukong, each watch reflects Oris' dedication to blending innovative technology with stylish design. The Oris Aquis collection combines rugged performance with thoughtful design, making it a standout choice for dive enthusiasts and collectors.

ABOUT THE MOVEMENT
The Oris calibre 400 is an in-house movement known for its unparalleled accuracy and strong magnetism resistance. It boasts a long 120-hour power reserve achieved with twin barrels while beating at a frequency of 4Hz. The movement can be admired through the sapphire crystal caseback and is composed of a unidirectional rotor and 21 jewels. It powers hours, minutes, seconds, and date complications in many Oris timepieces.
