Rolex Cosmograph Daytona 18 kt Everose Gold — Chocolate and Black Dial | Ref. 126505

Reference 126505 marks a significant moment in Daytona history as the first 40 mm Daytona produced in 18 ct Everose gold — Rolex's proprietary rose gold alloy engineered to resist fading over time through the addition of platinum to the metallurgical composition. The chocolate and black dial configuration gives this reference an immediately recognisable identity: the warm brown of the main dial registers against the black subdials in a tonal pairing that complements the warm tone of the Everose case. The engraved tachymetric scale on the fixed gold bezel is a functional motorsport legacy that lends the reference its chronograph identity.

Powering the 126505 is Calibre 4131, Rolex's manufacture chronograph movement developed for this generation, featuring a column wheel, vertical clutch for smooth chronograph engagement, and a 72-hour power reserve — a substantial advancement over the earlier 4130. The movement is regulated to Rolex's Superlative Chronometer standard, ensuring accuracy within plus or minus two seconds per day after casing. The 18 ct Everose gold bracelet, referenced in the listing, is the Oyster variant, with its broad three-piece links providing a substantial presence on the wrist consistent with the case's precious metal specification. Water resistance is rated to 100 metres.

The 126505 entered production as an immediate collector priority upon introduction, given the rarity of all-Everose gold Daytona references in the modern lineup. Like New/Unworn examples accompanied by box and papers — as described here — command the strongest secondary market premiums and are regarded as the benchmark condition for this reference. Buyers attracted to the chocolate dial configuration will find it represents one of the most compelling chromatic choices in the current Daytona range.
