First introduced in 1963, the Daytona was designed for the demands of professional racing drivers and was named after the famous racing site Daytona, Florida. In 2000, Rolex started a new line of luxurious Daytona watches for discerning collectors. The varying configurations of case material, use of precious stones and dial options continue to expand to this day. The current lot is presented in 18K white gold as denoted by the 9 to the end of the reference number and has a slate grey dial with contrasting red accents and hands creating a striking and contemporary feel. The 116519 is also powered by the in-house calibre 4130. This calibre has fewer components compared to other chronographs making it more reliable and offers additional space for a mainspring to increase the power reserve from 50 hours to 72 hours.
