ROLEX | Cosmograph Daytona Oyster 40 mm Everose-Gold Black Sundust 8 Diamonds | Ref. 126505
Concept & History
The chronograph for measuring average speeds has characterized the professional sports watch segment for decades. With the introduction of the reference 126505 In 2023, the model series underwent extensive architectural and mechanical modifications. This generation marks an evolutionary step in the history of racing chronographs, in which traditional design elements have been replaced by more precise case contours and a high-performance movement developed from scratch. The solid version in Everose gold represents the highest level of manufacturing expertise.
Caliber & Technology
The drive architecture is based on the completely redesigned manufacture movement Caliber 4131. The automatic switching wheel chronograph integrates the patented Chronergy escapement, which ensures stable Power reserve from 72 hours at a frequency of 28,800 A/h is achieved. The movement is characterized by a modified component architecture, which further maximizes operational reliability. A vertical clutch ensures an absolutely jerk-free start of the stop second. Certification as a superlative chronometer guarantees a maximum rate deviation of -2/+2 seconds per day.
Case & Material
The protective Oyster case with a diameter of 40 mm is forged from the brand’s proprietary Everose gold, which retains its brilliant color thanks to its platinum content. In the current generation, fine edges of Everose gold frame the engraved tachymeter bezel. The screw-down chronograph pushers and the Triplock winding crown guarantee a certified water resistance of 10 ATM. The solid Oyster bracelet made of Everose gold features the Oysterlock safety clasp as well as the Easylink system, which allows for a micrometric extension of 5 mm.
Aesthetics & Readability
The dial combines a deep black with sub-dials in a subtle sundust finish. Exclusive features include 8 diamonds in handmade Everose gold-settings, which replace the regular indices and subtly enhance the character of the reference. The harmonious symmetry of the tricompax arrangement facilitates intuitive reading of the stopped time intervals. Chromalight luminous material on the central hands ensures that information is conveyed quickly even in low light. The front is rounded off by a flat, extremely resistant Sapphire crystal.
