4 minutes read

Baselworld 2015 - Rolex is introducing the new generation of its most prestigious model, the Oyster Perpetual Day-Date, featuring a modernized design with 40 millimeter case as well as new mechanical movement, calibre 3255.

Rolex Day-Date 40

The new Day-Date redefines the status of superlative chronometer, established by Rolex in the late 1950s, with criteria for accuracy on the wrist that are twice as exacting as those for an officially certified chronometer.

Aesthetically, the new Day-Date inherits the evolutions that have marked the history of this very charismatic watch. It was launched in 1956, and the Day-Date was the first waterproof and self-winding chronometer wristwatch to offer a modern calendar with an instantaneous day display, spelt out in full in a window on the dial in addition to the date. President bracelet with an evocative name that, together with the eminent figures who have worn it, ensured the Day-Date became known as the "presidents' watch".

... A consummate demonstration of Rolex technology, with 14 patents, it offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetism, ease of use and reliability.”

In its new form, the Day-Date stands out with a range of elaborate new dials, a singular combination of high-technology and traditional know-how. Thin, laser-etched motifs are applied to a traditional sunray finish for a particularly sophisticated effect. The elegant and imposing President bracelet is inherent to the standing of the model. Immediately recognizable on a wrist, this solid gold or platinum bracelet with three semi-circular links provides complete reliability and comfort.

The new Day-Date is equipped with a new-generation movement, calibre 3255, entirely developed and manufactured by Rolex for a superlative level of performance. Certified as a Swiss chronometer by COSC, it is tested a second time by Rolex after being cased to ensure that in everyday use it satisfies Rolex's criteria for precision, which are twice as exacting as those for an officially certified chronometer. This self-winding mechanical movement is at the forefront of the art of watchmaking. A consummate demonstration of Rolex technology, with 14 patents, it offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetism, ease of use and reliability.

The new Day-Date is presented in 950 platinum or 18 ct yellow, white or Everose gold versions, with a variety of elaborate new dials.
