ROLEX OYSTER PERPETUAL COSMOGRAPH DAYTONA 40
Throughout its history Rolex has offered gem-set watches which became statements of beauty and engineering marvel with unmatched reliability, robustness, and resistance to magnetic fields and shocks. This year Rolex presented a new version of the Oyster Perpetual Cosmograph Daytona, with 40 mm case in 18 ct Everose gold. The watch looks absolutely striking with 56 brilliant-cut diamonds set into the lugs and crown guard, and the dial features 11 baguette-cut sapphire hour markers, each of which matches the color of the corresponding point on the bezel. The chronograph counters are in pink Gold Crystals, that has a unique shimmer effect, created during the crystallization of a pink gold alloy by means of a special process developed by Rolex. To adorn its timepieces with the most striking gemstones, the Roles has its own in-house gemologists and gem-setters. Gemologists are responsible for examining and selecting the gemstones, keeping only those that meet Rolex’s extremely stringent quality criteria. The stones then pass into the hands of the gem-setters, who are tasked with placing and fixing each stone to best reveal its beauty, color and sparkle.
The Cosmograph Daytona’s Oyster case, guaranteed waterproof to a depth of 100 meters (330 feet), is a symbol of robustness and reliability. Its middle case, with an integral crown guard, is crafted from a solid block of 18 ct Everose gold. The case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The winding crown, fitted with the Triplock triple waterproof system, screws down securely against the case, along with the chronograph pushers. The crystal is made of virtually scratch proof sapphire.
This new version of the Cosmograph Daytona is fitted on a solid-link Oyster bracelet in 18 ct Everose gold with ceramic inserts and an Oysterlock safety clasp to prevent accidental opening. The bracelet includes the Easylink rapid extension system, patented by Rolex in 1996, that allows the wearer to easily increase the bracelet length by approximately 5 mm for additional comfort.
The Cosmograph Daytona is equipped with calibre 4130. It’s a self-winding mechanical chronograph movement with a reduced number of components and a new levels of reliability, which is entirely developed and manufactured by Rolex. The robust chronograph is engaged by a mechanism with a column wheel and vertical clutch, providing an instant and extremely precise start. The oscillator, the true heart of the watch, has a blue Parachrom hairspring manufactured by Rolex in an exclusive paramagnetic alloy. Insensitive to magnetic fields, the Parachrom hairspring offers great stability in the face of temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. A Rolex overcoil ensures its regularity in any position. Calibre 4130 is equipped with a self-winding module via a Perpetual rotor and offers a power reserve of approximately 72 hours.
