Its design and quality Rolex Oyster Perpetual Cosmograph Daytona Diamonds Bezel Replica Watch 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.
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 Rolex Oyster Perpetual Cosmograph Daytona Replica Watch 40 mm Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness, proportion and elegance.
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. The Cosmograph Daytona is equipped with calibre 4130, a self-winding mechanical chronograph movement with a column wheel entirely developed and manufactured by Rolex.
This new Rolex Cosmograph Daytona Replica Watch is fitted with a solid-link Oyster bracelet in 950 platinum, with an Oysterlock safety clasp that prevents accidental opening.
Like all Rolex Replica Watch 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. 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.
