PRESTIGE AND REFINEMENT

Rolex is presenting three gem-set, colourful versions of its Oyster Perpetual Day-Date 36. Made from 18 ct yellow gold, 18 ct white gold and 18 ct Everose gold, these new watches are swathed in diamonds and fitted with a polished leather strap.

The Oyster case of these new timepieces is entirely set with 254 brilliant-cut diamonds on the lugs, lug caps and case sides. The bezel is also adorned with 52 brilliant-cut diamonds. The dial, paved with 450 diamonds, is host to index hour markers and Roman numerals VI and IX in enamel; these are coral-coloured on the 18 ct yellow gold model, turquoise on the 18 ct white gold version and burgundy on the watch in 18 ct Everose gold. These elegant appliques match the colour of the alligator leather strap for each of the new watches.

These new versions of the Day-Date 36 are equipped with calibre 3255, a movement at the forefront of watchmaking technology.

Like all Rolex watches, the Oyster Perpetual Day-Date 36 carries the Superlative Chronometer certification, which ensures excellent performance on the wrist.


EXCLUSIVITY ACCORDING TO ROLEX
At its launch in 1956, the Day-Date was a major innovation: it was the first calendar wristwatch to indicate, in addition to the date, the day of the week spelt out in full in an arc-shaped window at 12 o’clock on the dial – a technical feat at the time. The day of the week is available in a choice of 26 languages. Watches in the Day-Date range are made only of precious metals – 18 ct yellow, white or Everose gold or 950 platinum. Worn by many of the world’s political figures, directors and visionaries, the Day-Date is instantly recognizable, in particular thanks to its emblematic President bracelet, whose evocative name, together with the eminent figures who have worn it, ensured the Day-Date became known as the “presidents’ watch”.

THE OYSTER CASE

A paragon of robustness and elegance, the Oyster case of the Day-Date 36 is 36 mm in diameter. Its middle case is crafted from a solid block of 18 ct yellow, white or Everose gold. The case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The Twinlock winding crown, fitted with a double waterproofness system, screws down securely against the case. The crystal is made of virtually scratchproof sapphire and is fitted with a Cyclops lens at 3 o’clock for easy reading of the date. The waterproof Oyster case provides optimum protection for the watch’s movement.


PERPETUAL CALIBRE 3255
The new versions of the Day-Date 36 are equipped with calibre 3255, a movement entirely developed and manufactured by Rolex that was released in 2015 and has been fitted on this model since 2019. At the forefront of watchmaking technology, this self-winding mechanical movement led to the filing of several patents, and offers outstanding performance in terms of precision, power reserve, resistance to shocks and magnetic fields, convenience and reliability.

Calibre 3255 incorporates the Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic fields. The movement is fitted with an optimized blue Parachrom hairspring, manufactured by Rolex in a paramagnetic alloy that makes it up to 10 times more precise than a traditional hairspring in case of shocks. The blue Parachrom hairspring is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position. The oscillator is fitted on the Rolex-designed and -patented high-performance Paraflex shock absorbers, increasing the movement’s shock resistance.

Calibre 3255 is equipped with a self-winding module via a Perpetual rotor. Thanks to its barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 3255 extends to approximately 70 hours.

POLISHED LEATHER STRAP

The new versions of the Day-Date 36 are fitted on a polished alligator leather strap whose 18 ct gold folding Crownclasp is set with 61 brilliant-cut diamonds. The strap, which is coral on the 18 ct yellow gold model, turquoise on the 18 ct white gold version and burgundy on the third watch in 18 ct Everose gold, matches the colour of the enamel index hour markers and Roman numerals VI and IX on each of the watches’ diamondpaved dials.


SUPERLATIVE CHRONOMETER CERTIFICATION
Like all Rolex watches, the Oyster Perpetual Day-Date 36 is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria. These certification tests apply to the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The precision of a Rolex Superlative Chronometer is of the order of −2 /+2 seconds per day – the rate deviation tolerated by the brand for a finished watch is significantly smaller than that accepted by the Swiss Official Chronometer Testing Institute (COSC) for official certification of the movement alone.

The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
