Pre-owned Rolex Daytona ref 126503 (2024) made its debut early in 2023, featuring the first update to the in-house chronograph movement since Rolex released the caliber 4130 in 2000. The newer caliber 4131 features Rolex’s patented Chronergy escapement, Paraflex shock absorbers, Paramagnetic blue Parachrom hairspring, and a 72-hour power reserve. The newer movement is also beautifully decorated with Rolex Côtes de Genève, which we can see through the case back on the newer platinum models. Aside from the movement, Rolex has also made several small but thoughtful upgrades to the watch’s outward appearance. The lugs are now more symmetrical, and the hour markers, hands, and sub-dial rings have been thinned out to create a cleaner, more symmetrical appearance. Ref. 126503 is the Yellow Rolesor model in Oystersteel and 18k yellow gold. It sports a handsome matching champagne dial with black sub-dial rings. Shop Rolex Daytona Collection
