Rolex Cosmograph Daytona 126503 – Black Diamond Dial – Two-Tone (18K Yellow Gold & Oystersteel) – 2025 Q4 Card – Brand-New Full Set
The Rolex Daytona 126503 is a refined and powerful chronograph that marries luxury with performance. This model, produced in Q4 2025, comes in brand-new, unworn condition, complete with its original box and warranty card — an outstanding find for any serious collector or enthusiast.
Housed in a 40 mm Yellow Rolesor case (a blend of 18K yellow gold and rugged Oystersteel), the watch features a fixed yellow-gold bezel engraved with a tachymetric scale, a signature Daytona design detail that highlights its racing heritage. The dial is a standout: black with factory-set diamond hour markers, adding a touch of elegance and sophistication to a high-performance tool watch.
Inside, the watch is powered by the Rolex Calibre 4131, a finely engineered automatic chronograph movement with a ~72-hour power reserve, Paraflex shock absorbers, and a Triplock winding crown for maximum durability. The Oyster bracelet with its three-piece solid links ensures both comfort and reliability on the wrist.
