Introduced at Geneva Watch Days, the Oris AquisPro 4000M is the most water-resistant Oris watch ever produced.
Announced as part of the Geneva Watch Days, which started today, the Oris Aquispro 4000M is the most water-resistant dive watch Oris has ever produced. It is also one of Oris’ most voluminous watches with its 49.5 mm diameter titanium case.
The Aquispro 4000M, which has a 55 mm gap between two horns and a 23.4 mm case thickness, is designed with a locked bezel system called the Rotation Security System, which was developed together with professional divers. The screw-down crown is accompanied by a sapphire crystal glass and a ceramic bezel, which makes it easy to read the time even in the dark. Apart from its bulky size, its design features are similar to other models in the Aquis series.
The dial, designed in a blue that evokes the ocean depths (the average ocean depth is between 3,000 and 6,000 meters), is accompanied by the blue details of the 15-minute scale on the bright blue seconds hand and bezel, as well as the blue rubber strap.
At the heart of the AquisPro 4000M is the in-house caliber 400. Automatic movement caliber 400 beats at 28,800 VpH per hour and comes with a 120-hour power reserve.
