Rolex Daytona Steel — White Index Dial Black Cerachrom Bezel | Ref. 116500LN

Few references in modern watchmaking have generated the cultural gravity of the steel Cosmograph Daytona. The Oystersteel case measures 40mm — the canonical Daytona dimension unchanged since Paul Newman's era — and houses three integrated sub-registers: a 30-minute counter at 3 o'clock, a 12-hour counter at 9 o'clock, and a running seconds indication at 6 o'clock. The black monobloc Cerachrom bezel, introduced with this generation, is machined from a single piece of ceramic, rendering it virtually scratch-proof and immune to ultraviolet fade, while its engraved tachymetric scale allows instantaneous calculation of average speed over a measured distance.

The movement within is the Calibre 4130, one of the most celebrated chronograph ebauches in contemporary horology. A vertically-coupled clutch — in contrast to the lateral clutch used in many competitor movements — ensures the chronograph seconds hand engages without the characteristic jolt at start, a refinement valued by serious practitioners. The column-wheel provides precise, tactile control of start, stop, and reset functions. Power reserve extends to approximately 72 hours, and the movement is COSC-certified before being further regulated by Rolex to -2/+2 seconds daily.

The white dial with index hour markers offers a compelling contrast to the black Cerachrom bezel — a juxtaposition that has proven definitively more desirable on the secondary market than any other Daytona configuration of this generation. Protected by scratch-resistant sapphire crystal and water-resistant to 100 metres via the screw-down Triplock crown, this reference needs no additional context to command attention. It is simply one of the most important sport watches of the 21st century, presented in its most elemental and covetable configuration.
