Since the milestone of the firm’s very first model to feature a self-winding caliber based on the famous Zenith El Primero movement released in 1988, the Rolex Cosmograph Daytona ref. 16520 has enjoyed tremendous success for over a decade of nothing else but soaring demand and praise. With Rolex’s rigors in developing innovations and advancements, the reference was discontinued in 2000 to make way for Rolex’s first ever in-house chronograph calibre 4130 with the reference 116520.

Growing in demand, the Cosmograph Daytona’s evergreen modern design has garnered the attention from vintage collectors all around the globe, and have become on the most sought after sports watch. Produced in circa 1989, the present example bearing an L serial is from the rare and coveted early examples of Zenith Daytona. The first half of the production of the “L” series houses a 4-Liner dial with a MK I 200 units per hour bezel insert, followed by a very short run of MK II bezel like the present example, where the bezel was modified with a scale for 400, 250 and 225 indication, and “units per hour” has been relocated to 1 o’clock position. Adding attraction to this incredibly well-preserved example is the feature of an inverted 6 on the 12-hour register, making this one of the most desirable combination from the series. Offered by the original owner and preserved in stunning condition boasting a strong case, the present early specimen is charmed with its original guarantee and presentation box, making this a highly collectable chronograph from the era.
