In 1988, Rolex launched the first self-winding chronograph wristwatch in its history to celebrate the 25th anniversary of their first Cosmograph Daytona. The watch houses the Rolex caliber 4030, based on Zenith’s El Primero movement, with substantial modifications performed by Rolex. To accommodate a sapphire crystal for the first time and to house the new movement, the Daytona’s case size was increased to 39 millimeters. This example features a pristine white dial, with contrasting black subsidiary rings. Bearing a “W” serial number, this Daytona is correctly fitted with the rare and highly sought after ‘400’ graduation bezel. It is impossible for the condition of this watch to go unnoticed. It is presented in near mint condition, further evidenced by the original green Rolex sticker on the caseback. The present watch is accompanied by the original Rolex guarantee confirming it was purchased at Murray Jewelers, in Muncie, Indiana. Additionally, it is presented with the original box, a Rolex polishing cloth, the original Rolex hangtags and a plastic protective ring on the bezel. Such a complete and immaculate watch is an opportunity that does not come around often, and is sure to satisfy the most discerning collectors of Rolex sport watches.
