Big and bold may be the first words that come to mind when setting eyes on the latest Oris dive watch, the AquisPro Date Calibre 400. And for good reason. Its titanium case with black DLC coating, topped with a black ceramic rotating dive bezel, weighs in at an impressive 49.5mm diameter… which doesn’t prevent it from feeling light and comfortable on the wrist. Importantly, indications remain clearly legible even when testing the watch’s 1,000-metre depth rating, thanks to the luminescent treatment on the large indices and hands that circle the black, wave-patterned dial. The movement is the in-house developed and manufactured Calibre 400. Ticking the boxes for performance and reliability, it has elevated anti-magnetic properties and stores five days of power reserve in its twin barrels. As for accuracy, at - 3/+ 5 seconds a day, Oris guarantees precision beyond COSC standards.
