Oris Watch Divers Sixty Five 12H Calibre 400 01 400 7772 4054-07 5 20 82. The Oris Watches Divers Sixty Five 12H Calibre 400 spans more than half a century of Oris watch design and movement creation. The spirit of Oris’s first diver’s watch, introduced in 1965, continues to inspire the form of the Divers Sixty-Five, only now it’s equipped with Oris Calibre 400, our game changing automatic. This means the new watch has elevated levels of anti-magnetism, a five-day power reserve, a 10- year warranty and 10 year recommended service intervals. The new standard now applies to our evergreen diver’s watch. But that’s not where the updates end. Because this is also the first Divers Sixty Five with a 12-hour bi-directional rotating bezel, designed to serve as a second time zone. Finishing touches include a sapphire crystal case back and the choice of either a leather strap or metal bracelet. At Oris, time never stands still.
