Rolex Cosmograph Daytona Yellow Gold — Blue Arabic Dial | Ref. 116508

Produced prior to the introduction of Calibre 4130's successor generation, reference 116508 in 18-carat yellow gold with a blue Arabic dial occupies a distinguished position in the Daytona lineage — a reference that collectors have consistently reappraised upward as examples transition from new-old-stock to sought-after secondary market pieces. The 40 mm yellow gold Oyster case, machined to Rolex's characteristic surface-finish tolerances and sealed by a screw-down case back, is encircled by a fixed yellow gold bezel carrying an engraved tachymetric scale: the functional signature of the racing chronograph since 1963.

Calibre 4130, a self-winding mechanical chronograph movement of singular engineering achievement, drives the three-register layout with a vertical clutch that ensures the central chronograph seconds hand departs precisely from zero at every activation. The free-sprung, variable-inertia balance and Parachrom hairspring deliver chronometric performance certified to Superlative Chronometer standards, while an approximately 72-hour power reserve accommodates extended periods off the wrist. Arabic numerals rendered in matching blue across the trio of sub-dials — small seconds at nine, thirty-minute counter at three, twelve-hour counter at six — create a cohesive chromatic narrative across the entire dial.

An 18-carat yellow gold Oyster bracelet with flat three-piece solid links, fastened by the Folding Oysterlock buckle with Easylink extension, confers both physical security and the unmistakable gravity of solid precious metal against the wrist. Push buttons sealed to Triplock waterproofness standards and screw-down crown complete a water-resistance rating of 100 metres. Reference 116508 in this configuration is a foundational piece for any serious horological collection: irreducible, iconic, and appreciating with purpose.
