ROLEX OYSTER PERPETUAL DAY-DATE “SERTIE”

At BASELWORLD 2013, Rolex is honouring the art of dial making and traditional gem setting with a selection of seven “Oyster Perpetual DAY DATE” models in gold graced with diamonds, mother-of-pearl and fine coloured gemstones. Each of these new DAY-DATE models has a distinctive, sophisticated, rich dial, conceived and produced in-house by Rolex dial makers. All of the bezels are set with baguette-cut diamonds.

MOTHER-OF-PEARL, GOLD AND DIAMONDS: Using exclusive techniques and a subtle juxtaposition of materials, two new creations emphasize the natural beauty of mother-of-pearl. The mother-of-pearl carousel dial features an openwork design hour ring in 18 ct white gold set with 217 diamonds and delicately inlaid with pink or white mother-of-pearl, engraved with a floral motif. Inspired by the famous English fabric, the oxford dial presents a basket-weave motif engraved on either white mother-of-pearl or on enigmatic mother-of-pearl with platinum reflections obtained via a special process developed by Rolex. These two creations with diamond-set hour markers and bezels are offered on the DAY-DATE in 18 ct EVEROSE or white gold.

FASCINATING GEMSTONE DIALS: Rolex is introducing new versions of fine gemstone dials enhanced by the brilliance of diamond-set hour markers: lapis lazuli on the 18 ct white gold model, bull’s eye on the 18 ct yellow gold model and ferrite on the 18 ct EVEROSE gold model, with diamond-set bezels.

THE OYSTER CASE, SYMBOL OF WATERPROOFNESS AND ELEGANCE: The 36 mm OYSTER case of the DAY-DATE “SERTIE”, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness, 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 crystal, with a CYCLOPS lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire. The waterproof OYSTER case provides optimal protection for the high-precision movement of the DAY-DATE “SERTIE”.

CALIBRE 3155, A SUPERLATIVE CHRONOMETER: The DAY-DATE “SERTIE” models are equipped with calibre 3155, a self-winding mechanical movement with a day and date display entirely developed and manufactured by Rolex. Like all Rolex 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 design and quality manufacture provide peerless precision and reliability. 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 in case of shocks than a traditional hairspring.

OYSTER BRACELETS AND CONCEALED CLASPS: The new DAY-DATE “SERTIE” models are fitted with an OYSTER bracelet in 18 ct yellow, white or EVEROSE gold featuring a concealed folding CROWNCLASP. This elegant, solid-link bracelet with both satin and polished finishes is remarkably comfortable to wear and effortless to open and close.
