Ref. 16520
Known as the “Zenith Daytona,” the reference 16520 holds a significant place in Daytona history as the first model to feature an automatic chronograph movement and a sapphire crystal, powered by a Zenith-derived caliber based on the legendary El Primero.
This example featuring a black dial, has been preserved in pristine condition, showing barely any signs of wear and comes complete with its original box and papers.
