Description: Rolex Daytona 126500 Pre-owned Rolex Daytona ref 126500 (2024). A brand-new generation of Daytonas debuted in 2023, replacing the outgoing 1165XX generation and bringing, for the first time since the release of caliber 4130 in 2000, a newer movement and a host of cosmetic upgrades. The newer caliber 4131 has fewer components and sports a lovely Côtes de Genève decoration, which we can only admire so far on the platinum models with exhibition case backs.
