Rolex Daytona Movement Zenith

The Rolex Daytona Zenith movement, introduced in 1988, marked a bold new chapter for the iconic chronograph, seriously, it’s a real milestone; Rolex sourced the El Primero base from Zenith, then stripped it down and rebuilt it—because of course they did—to create the caliber 4030. Collectors love it for its precision, its history, and well, its story. At Tropical Watch, we’re all about connecting you with these rare pieces that, honestly, just get better with time.
