http://www.thewatchbox.com The Rolex Cosmograph Daytona is a legend and an icon. Long the only watch equally welcome poolside and trackside at the world's biggest races, the Daytona is redolent of 100-octane and testosterone. Since 1965, Rolex has sponsored the annual mid-winter 24-hour endurance race, and the company's legendary chronograph has been presented to the fortunate victors in each class. Also owned and worn by the likes of driver/actor Paul Newman and Sir Jackie Stewart, the Daytona enjoys a pedigree and history that is second to none. This Rolex Daytona in 18-karat yellow gold features Rolex's own blend of gold, a unique product that will never fade or change color like inferior gold alloys commonly used in the luxury watch industry. This outstanding quality is achieved thanks to Rolex's control of the entire metallurgical process; the company is among the few watchmakers that owns and runs an in-house foundry. This Cosmograph Daytona combines Rolex yellow gold with a unique stabilized mother of pearl dial. The nautical jewel is leveled and brushed with an upper coating that enhances the prismatic effect of the minerals within. Its shifting color and layers create a standout timepiece that is unique even among the rarefied ranks of Rolex Daytonas. Moreover, this 1997 Rolex Cosmograph Daytona incorporates a Rolex-modified Zenith El Primero chronograph movement. Already famous as the first automatic chronograph movement in Swiss history, the El Primero was covered in glory when Rolex selected it to power the Geneva giant's vaunted Daytona. Upgraded with Rolex parts and engineering, the El Primero in "Daytona spec" is a COSC-certified chronometer with durability that surpasses the Zenith original. Available from thewatchbox.com, this Rolex Cosmograph Daytona in 18k yellow gold is among the few also built with a mother of pearl dial. It's a quintessential sports watch that also excels as a dress watch. A perfect companion for the discerning watch collector, the Daytona may be the most stylistically versatile Rolex money can buy.
