The Rolex Cosmograph Daytona reference 126509 is one of the most compelling modern Daytona configurations Rolex has ever produced. Crafted in solid 18k white gold and paired with a vivid blue sunburst dial accented by red “DAYTONA” text, it delivers a combination of presence and restraint that has made it a standout among collectors.
Often referred to as the “Baby John Mayer,” this reference draws its appeal from the same unmistakable color contrast as its platinum counterpart, while remaining far more wearable and understated on the wrist. The white-gold case keeps the watch discreet, while the dial provides just enough visual energy to separate it from the traditional steel and black-dial variants.
At its core is Rolex’s in-house Caliber 4130, a benchmark automatic chronograph movement known for its reliability, efficiency, and clean architecture. With a 72-hour power reserve and proven long-term durability, it is a movement built to be worn regularly, not hidden away.
This 2020 example is offered as a complete full set and remains in very good condition, showing only light signs of careful use. It is an excellent opportunity to acquire one of the most balanced and desirable modern Daytona references with full provenance.
Complete Set Information
This watch is offered as a full set and includes the original inner and outer Rolex boxes, warranty card dated 2020, original papers and manual, and the serialized white hang tag. The watch is in very good condition with minor wear consistent with occasional use. No deep scratches, dings, or service needs are present. Light desk-diving marks are visible on the clasp.
