Equipped with Rolex calibre 4130BASELWORLD 2014: A new jewelled version of the Oyster Perpetual Cosmograph Daytona
Rolex presents a new jewelled version of the Oyster Perpetual Cosmograph Daytona that combines the nobility of 950 platinum and the radiance of purest-quality diamonds. The dial is entirely paved with diamonds, apart from the ice blue chronograph counters.
Rolex reserves this rare and exclusive colour for platinum models. The resplendent bezel is set with 36 baguettecut diamonds.
The Oyster Case
The Cosmograph Daytona’s 40 mm Oyster case, 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 950 platinum, the noblest of precious metals. The fluted case back is hermetically screwed down with a special tool exclusive to Rolex watchmakers. The winding crown, fitted with the patented Triplock triple waterproofness system, screws down securely against the case. It is protected by a crown guard that forms an integral part of the middle case. The pushers also screw down securely against the case. The crystal is made of virtually scratchproof sapphire. The waterproof Oyster case provides optimal protection for the Cosmograph Daytona’s high-precision movement.
The Cosmograph Daytona is equipped with calibre 4130, a self-winding mechanical chronograph movement with a column wheel entirely developed and manufactured by Rolex. Like all Rolex Perpetual movements, the 4130 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 ensure 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 of niobium and zirconium. 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.
Solid-link bracelet and safety clasp
This new Cosmograph Daytona is fitted with a solid-link Oyster bracelet in 950 platinum, with an Oysterlock safety clasp that prevents accidental opening. The bracelet also features the ingenious Rolex-patented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
