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 indications, 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 combinations from the series.

The present example Rolex Cosmograph Daytona ref. 16520 from circa 1989 with a “L506’701” case number and a correct “18’981” movement number featuring a white dial and MK II bezel is offered with its full set of accessories and preserved in attractive overall condition boasting a sharp case. For lovers and collectors of rare and desirable Daytonas, this is not only a great example to complete the missing puzzle in the collection, but the very one that is published and archived in the famous bible Daytona Perpetual book by Pucci Papaleo.
