Rolex Daytona Zenith 16520

The Rolex Daytona Zenith 16520—yeah, that one—is kind of a big deal. Introduced in 1988, it marked the first time Rolex used an automatic movement in the Daytona, borrowing and modifying Zenith’s El Primero. It’s iconic, crazy collectible, and honestly, just plain cool. At Tropical Watch, we’ve seen it all—from perfectly preserved examples to those with dials turning warm, rich tones. That patina? Serious collectors chase it.
