Oris Divers Sixty-Five 12H Calibre 400

The new 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, brand's 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.
