Oris Divers Sixty-Five Calibre 400 01 400 7772 4054-07 8 20 18. Finished in a multi-piece stainless steel case and bracelet with a beautiful Black dial. The Divers Sixty-Five features a 40mm case and a hour scale top ring. The Sapphire crystal glass is domed on both sides and has anti-reflective coating on the inside. Water resistance rating is 100m.

Calibre 400 is an entirely new movement, independently conceived by Oris, and sets the new standard for automatic mechanical movements. It has a five-day power reserve (120 hours), is highly resistant to magnetism, and comes with 10-year recommended service intervals and a 10-year warranty.

When conceptualising Calibre 400, Oris’s engineers recognised that these days we may not wear the same watch every day. If you put a standard mechanical watch down for a day or two, it will stop as the power reserve runs down. Calibre 400 has a five-day power reserve, so it’ll still be running if you’ve not worn your watch between, say, Thursday and Tuesday. It delivers this longer period of use via twin barrels, both of which house an extended mainspring, each long enough to store two-and-a-half days of power. It’s highly accurate, to -3/+5 seconds a day, better than a chronometer.

What we like: The depth of the dial is mesmerising. The intricacy of the movement aside, the look of the classic Divers Sixty-Five is timeless and makes this a watch to own and enjoy.
