Rolex Daytona White Gold — Steel and Black Dial | Ref. 116509

Reference 116509 is the Cosmograph Daytona in 18-carat white gold, a material that lends the 40 mm Oyster case a cooler, more austere presence than its yellow or Everose gold counterparts. The dial configuration here deploys a steel subdial surround against a black main dial — a combination commonly designated 'steel and black' — with the three chronograph registers at 3, 6, and 9 o'clock rendered in contrasting tones that sharpen legibility at a glance. The tachymetric scale is engraved directly into the bezel rather than applied as an insert, a hallmark of precious metal Daytona references.

Calibre 4130 — or its updated derivative Calibre 4131, depending on production date — powers the 116509. This movement, developed entirely in-house and introduced in 2000, marked a watershed moment for the Daytona line following decades of reliance on the Zenith El Primero base. The 4130 oscillates at 28,800 vph with a column-wheel vertical clutch for instantaneous chronograph engagement and delivers a 72-hour power reserve via twin barrels. The Chronergy escapement, present in later production, improves energy efficiency by approximately 15 percent over conventional lever geometries.

The white gold Daytona occupies a particular position in the secondary market: produced in far smaller numbers than the Oystersteel references yet less prominent than the meteorite or coloured-dial variants, the 116509 in a steel-and-black configuration represents a relatively understated entry into the white gold Daytona universe. Waiting lists for new examples have historically been significant, reinforcing the desirability of well-documented pre-owned pieces.
