replica Rolex watches launches the new Oyster Perpetual Cosmograph Daytona 904L in steel with a black ceramic Cerachrom bezel developed and patented by Rolex. This latest design is a tribute to the tradition of excellence of this legendary timepiece, which combines high technology with exceptional aesthetics. The black bezel follows the design of the 1965 version of the black Plexiglas bezel. The new Cosmograph Daytona has been certified by Rolex as a top chronometer since 2015, guaranteeing maximum performance on the wrist.
Created in 1963, the Oyster Perpetual Cosmograph Daytona was specially designed for the racing world, where its reliability and outstanding performance made it an outstanding success. Under the name of “Daytona”, it has become one of the classic timepieces and a highly sought-after chronograph throughout the world. It features a tachymeter engraved on the bezel, which can measure average speeds of up to 400 mph or kilometers per hour. The new high-tech Cerachrom ceramic bezel offers a number of advantages. It is resistant to corrosion and scratching and does not fade even when exposed to ultraviolet light. The Cerachrom bezel is a one-piece piece that helps to hold the mirror to the case and ensures water resistance.
The Oyster case of the Cosmograph Daytona is guaranteed water-resistant to 100 metres (330 feet) and is an example of rugged elegance and perfect proportions. The uniquely shaped middle case is cast in a solid block of 904L steel. Only a Rolex watchmaker can open the movement by tightening the triangularly pitted caseback with a special tool exclusive to the brand, which seals the case. The winding crown, equipped with Rolex’s patented triple waterproofing system with a triple-locking clasp, is screwed securely to the case, as are the chronograph pushers, and is protected by a crown guard. This crown guard is integrated into the middle case. The crystal, made of sapphire crystal, is not susceptible to scratching. The water-resistant Oyster case of the Cosmograph-Detonation offers optimal protection to the high-precision movement.
It is equipped with the 4130 self-winding mechanical chronograph movement, entirely developed and manufactured by Rolex. Its construction has been completely revolutionized, in keeping with Rolex’s watchmaking expertise, and the number of chronograph components has been considerably reduced to make the movement more reliable. The sturdy chronograph movement is equipped with a column wheel and a vertical chronograph clutch, enabling the chronograph to be instantly activated and thus to be kept precise. The balance cock, the heart of the watch, is equipped with a Rolex patented blue Parachrom hairspring made from a unique alloy forged by Rolex. This hairspring is impervious to magnetic fields, remains stable even at varying temperatures and is ten times more resistant to shocks than a traditional hairspring. The 4130 calibre is equipped with a self-winding assembly with a constant motion oscillating weight and a power reserve of approximately 72 hours.
The new Cosmograph Daytona is fitted with a 904L steel solid link Oyster bracelet with an Oyster safety clasp to prevent accidental opening of the buckle. The clasp is fitted with Rolex’s patented easy-adjust links, a clever extension that allows the wearer to easily extend the bracelet by approximately 5 mm for greater comfort in all conditions.
The Cosmograph Diatonné has been certified as a top chronometer by Rolex, a new standard laid down in 2015. This unique designation confirms that the watch has successfully passed a series of tests conducted by the Rolex laboratory, which go beyond the usual norms and standards of the watchmaking industry. The watches are tested after assembly to ensure that, when they are worn on the wrist, they perform at the highest level in terms of precision, power reserve, water resistance and automatic winding. The Rolex Chronometer, whose movement is mounted in the case and then tested, averages an error of less than plus or minus two seconds per day – twice as accurate as an ordinary chronometer. The green seal, the emblem of a Top Chronometer, is attached to every Rolex watch and comes with a five-year worldwide warranty.
