Rolex

The year 1988 marked the end of Rolex’s famed four-digit Daytona references. That same year, at the Baselworld International Watch Show, the brand unveiled a new generation of Daytona models, representing a significant technical milestone. For the first time, the Daytona was powered by an automatic movement, the modified Zenith El Primero, known as Rolex caliber 4030. This marked a major advancement over its manual-winding predecessors and would also represent the final chapter of outsourced chronograph movements for Rolex, prior to its transition to fully in-house calibers. As a result, the “Zenith Daytona” has become one of the most sought-after modern Rolex references among collectors.

Throughout its production from 1988 to 2000, the Zenith Daytona underwent a series of subtle evolutions as Rolex refined its design. The present watch features the highly desirable Mark 1 dial, distinguished by two key traits that make these early examples particularly collectible. Most notably, the word “Cosmograph” is positioned noticeably lower beneath the four lines of text above, creating the so-called “Floating Cosmograph” configuration seen only in the earliest years of production. It also displays the coveted “inverted 6” on the 6 o’clock subdial. Additionally, the watch is fitted with the early Mark 1 bezel, calibrated to 200 units per hour, rather than the 400-unit scale seen on later iterations.

We are proud to present this watch at auction for the first time at Sotheby’s. It is consigned directly by the wife of the original owner, whose name is engraved on the caseback. Acquired as an anniversary gift in 1989, she quietly worked an additional job for a year to save for the purchase without his knowledge. The watch is accompanied by its original wooden presentation box with outer packaging, Certificate of Origin, and is preserved in excellent overall condition.
