As the moniker suggests, the “Zenith” Daytona is coveted by watch collectors due to the special movement utilized by Rolex. Caliber 4030 found within Reference 16528 is a heavily modified automatic chronograph movement based on Zenith’s El Primero Caliber 4030. Over 200 modifications were completed on the El Primero based caliber in order to meet the exceptional standards of excellence from Rolex.

The dial is near flawless and features gold-tone subsidiary registers that perfectly compliment the case and bracelet. The present lot has a screw down crown and pushers to help maintain Rolex’s guarantee of 100 meters. This Zenith Daytona is fitted onto an 18k yellow gold Oyster Bracelet with the clasp stamped “78398”, matching the production year of the watch head.
