Rolex Daytona White Gold — Black Diamond Dial | Ref. 116509

Reference 116509 is the white gold iteration of the Cosmograph Daytona—a chronograph whose status in modern horology is virtually unparalleled. White gold softens the Daytona's traditionally sporty character into something more refined, and the black diamond dial with its tachymetric bezel in matching 18ct white gold creates a monochromatic drama rarely achieved in sports watches.

At the heart of the 116509 is Calibre 4130, Rolex's entirely in-house column-wheel chronograph movement featuring a vertical clutch mechanism for instantaneous chronograph engagement without hand-jump. It delivers a 72-hour power reserve and operates at 28,800 vph. The dial's subdial counters—at 3, 6, and 9 o'clock—are set with diamond hour indices in place of the standard batons, adding further gemological density. The 40mm white gold Oyster case is water-resistant to 100 metres, and the pushers and crown maintain Rolex's characteristic Triplock and Pushdown crown system.

White gold Daytonas occupy a distinct collector tier above steel references, and Reference 116509 with a black diamond dial represents a specification that performs consistently well at major auction houses. The combination of precious metal, in-house chronograph movement, and diamond-set dial appeals to collectors who require both horological credibility and jewellery-grade presentation. It is equally at home on a formal dinner setting as on a circuit paddock.
