Notes

Dial, case and movement signed. DIAM. 40 mm. THICKNESS 12.5 mm. Approx. overall length 170 mm. Part of the desirable ROLEX DAYTONA's fitted with the famous Zenith caliber, this watch was made during the second year of its production (L series). Instantly recognizable due to the lack of the writing "Officially Certified" on the dial, its attractiveness is further enhanced by the dial that has changed to a warm ivory color and the presence of the original punched warranty.
