Although the golden brilliance is totally enticing, the brown crocodile skin strap with a white gold folding clasp is what attracts most professionals to Rolex 116519/4. The Rolexfeatures a white gold case of 40mm girth and a glimmering gold bezel with a tachymeter attached and a scratch-resistant sapphire crystal. Rolex Cosmograph Daytona 116519/4 is 100-meter waterproof which is greatly enhanced by the screw-down Triplock winding crown and the firmly-closed solid caseback. To tell the time, Rolex crafted the racing Daytona with a white dial which has bold gold Arabic numerals, luminescent centered hands, and three black sub-dials. The large Rolex Daytona is powered by a 44-jewel caliber 4130 self-winding movement which offers diverse functions such as center hour, small seconds, and chronograph.
