Rolex Daytona Yellow Gold — Champagne Diamond Dial | Ref. 116518LN

The Cosmograph Daytona in reference 116518LN represents the definitive intersection of motorsport heritage and haute joaillerie. Housing a 40 mm case in 18-carat yellow gold, the watch is anchored by a black monobloc Cerachrom bezel — Rolex's proprietary ceramic compound — engraved with a tachymetric scale that permits direct speed calculation from elapsed time. The champagne dial is appointed with eight diamond hour markers that replace the standard indices, introducing a layer of refinement without compromising the chronograph's functional legibility.

The movement is calibre 4130, Rolex's in-house self-winding chronograph calibre, notable for its column-wheel activation, vertical clutch engagement, and approximately 72 hours of power reserve. The vertical clutch architecture eliminates the hands-jump phenomenon common in lateral-clutch designs, ensuring the chronograph seconds hand springs from precisely zero on activation. The 30-minute counter at three o'clock and 12-hour counter at nine o'clock complete the three-register layout in the tradition established by Daytona references dating to the 1960s.

Carried on a black Oysterflex strap — Rolex's flexible metal-blade construction overmoulded with high-performance elastomer — the 116518LN delivers the tactile luxury of a rubber sports strap with the structural integrity of a metal bracelet. The Oysterlock folding safety buckle with Easylink 5 mm rapid extension system ensures both security and comfort adjustability. Water-resistant to 100 metres. A Daytona in precious yellow gold with diamond hour markers is among the most sought-after configurations in the modern Rolex sports catalogue.
