For the reference 16520, Rolex modified the Zenith movement to beat at 28,800 vibrations per hour, ensuring greater precision and reliability. As one of the final Daytonas to feature the El Primero movement, the reference has become a highly coveted model among collectors. Presented in stainless steel with the classic Oyster case and bracelet, it represents a pivotal moment in the evolution of the Daytona.
