Day-Date Or Everose

OYSTER PERPETUAL DAY-DATE

Symbol of prestige and exclusivity, available only in precious metals, the Oyster Perpetual DAY-DATE presented at BASELWORLD 2012 puts a new face on the leading watch of influential people.

when it appeared in 1956, the DAY-DATE was the first wristwatch with a calendar indicating the day of the week spelt out in full in a window on the dial. The DAY-DATE adorned with a new gem-set dial perpetuates Rolex’s legendary excellence and displays all the brand’s watchmaking know-how and technology.

Chocolate, diamonds and rubies
In an 18 ct EVEROSE gold case of incomparable lustre, this DAY-DATE is fitted with a chocolate colour dial on which the hours are marked by precious stones: eight diamonds and, at 6 o’clock and 9 o’clock, baguette-cut rubies.

Rolex pink gold
The 18 ct EVEROSE gold of the OYSTER case and bracelet is alloyed by Rolex in its own foundry before being shaped in the brand’s workshops. The incomparably warm tone of this exclusive pink gold alloy developed by Rolex is heightened by the addition of a touch of platinum. Its unique lustre is the result of the extreme care with which it is shaped, machined and finally polished.

The OYSTER case, symbol of waterproofness
The DAY-DATE’s 36 mm OYSTER case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of proportion and elegance. The characteristically shaped middle case is crafted from a solid block of 18 ct gold. The fluted case back is hermetically screwed down with a special tool exclusive to Rolex watchmakers. The winding crown, fitted with the patented TWINLOCK double waterproofness system, screws down securely against the case. The fluted bezel is a Rolex signature aesthetic feature. The crystal, with a CYCLOPS lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof synthetic sapphire. The waterproof OYSTER case allies refinement with efficiency in protecting the DAY-DATE’s high-precision movement.

Calibre 3155, a superlative chronometer
This DAY-DATE is equipped with calibre 3155, a self-winding mechanical movement entirely developed and manufactured by Rolex. Like all PERPETUAL movements, the 3155 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. Its architecture, like that of all OYSTER watch movements, makes it singularly precise and reliable. The oscillator, the true heart of the watch, has a blue PARACHROM hairspring patented and manufactured by Rolex in an exclusive alloy. Insensitive to magnetic fields, the PARACHROM hairspring offers great stability when exposed to temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks.

Comfort and elegance of the OYSTER bracelet
This DAY-DATE model is fitted with an 18 ct EVEROSE gold OYSTER bracelet with a concealed folding CROWNCLASP. Developed and patented by Rolex, this elegant solid-link bracelet offers remarkable comfort and ease of use.
