Rolex Cosmograph Daytona 18ct Yellow Gold — Bright Green & Golden Dial | Ref. 126508

Reference 126508 stands among the boldest statements in the modern Daytona canon: a 40 mm Cosmograph case crafted entirely in 18-carat yellow gold, framed by a black monobloc Cerachrom bezel whose ceramic tachymetric scale is impervious to ultraviolet fading and virtually scratch-proof. The dial configuration — a vivid bright green racing field with golden sub-register surrounds — introduces a chromatic vocabulary that references the racing circuits from which the Daytona derives its name, where the boundary between danger and glory has always been coloured in extremes.

At the movement level, Calibre 4130 — Rolex's entirely in-house chronograph calibre — achieves a vertical clutch mechanism and column-wheel control that guarantee instantaneous chronograph engagement with zero jump in the central seconds hand. The paramagnetic blue Parachrom hairspring, paired with Paraflex shock absorbers, provides chronometric resilience under physical stress; Superlative Chronometer certification confirms accuracy to -2/+2 seconds per day. An approximately 72-hour power reserve, delivered by bidirectional winding via the Perpetual rotor, means the watch runs through an entire competition weekend without attention.

The Oyster bracelet in 18-carat yellow gold, secured by the Folding Oysterlock safety clasp with Easylink 5 mm comfort extension, completes a timepiece that is simultaneously a precision instrument and a grand complication in jewellery terms. Screw-down pushers and a Triplock triple waterproofness crown deliver 100-metre water resistance. Acquired in Like New condition with full box and papers, this 126508 represents a pristine example of a reference already commanding significant collector attention in the secondary market.
