Oris Divers Sixty-Five 12H Calibre 400 

Oris has always been synonymous with value – watches that provide a certain bang-for-buck in terms of style and substance. The brand has always had style on its side, and has recently made great strides in movement manufacturing – releasing impressive in-house calibres that represent great value in the world of watchmaking. Oris has always been the brand that has delivered on value, never leaving customers short on things that they want from a watch, and at Geneva Watch Days, Oris unveils the Divers Sixty Five 12H Cal. 400 – a watch that exudes practicality, combined with rugged good looks from the 60s.

Originally conceived in 1965, the Divers Sixty Five 12H Cal. 400 is a watch that carries the essence of the original dive watch from Oris, whilst containing the conveniences of modern watchmaking, as well as a few design tweaks from the original Divers Sixty Five that gives it extra functionality. 

Sporting a 40mm stainless steel case, the watch features a design with no crown guards, in line with its vintage aesthetic, and enables it to fit many wrists with its symmetrical design. The bezel has an anodized aluminium insert, and, unlike many dive watches, it is able to be rotated bidirectionally. This leads to its second peculiarity – the bezel insert itself. On a normal diver’s watch, it would usually be a graduated diver’s scale in minutes, however on the Divers Sixty Five 12H Cal. 400, it is a 12 hour bezel, enabling it to be rotated to accommodate a second timezone.

The dial is highly legible during the day and the night – a black dial with applied indices filled with white SuperLuminova gives great contrast for easy reading. Conveniently, a date is included in this watch, situated at 6 o’clock. All of this, inside a 100m water resistant case gives the watch everything it will need to survive most everyday situations, including a small dip in the pool. The watch is available on a leather strap with stainless steel buckle, or a stainless steel bracelet that is styled to look like a vintage riveted bracelet – complete with folding clasp.

Housed within its case is the Oris in-house Calibre 400, manufactured for reliability and everyday utility. A 5 day power reserve enables the wearer to set the watch down for a reasonable period, and pick it up again without having to worry about the watch running out of power. It also fulfils the international standards for anti-magnetic protection through the use of specialised components – more than 30 components are made from anti-magnetic materials, thus protecting the movement from everyday magnetic fields put out by objects like laptops, tablets and even purse clasps. Signifying ultimate confidence in the reliability of their movement, the watch comes complete with a 10 year warranty, one of the longest warranty periods in the industry.

The Oris Divers Sixty Five 12H Cal 400 stands out as a watch that is reasonably priced, offers the best of vintage aesthetics and modern watchmaking sensibilities. With an industry leading warranty, a movement designed with the wearer in mind, and everyday good looks, it is no wonder the Divers Sixty Five collection continues to be a fan favourite, and this new release will be one that budding watch enthusiasts can enjoy for decades to come.
