The present watch was created two years after the model debuted, featuring the L serial number which indicates a 1990 production year. The present lot is fitted with an alluring and very rare “Mark II” black dial in like new condition. There are several characteristics that make the “Mark II” so coveted and widely revered. Firstly, the dial configuration was in production for a short period of time and fitted on very few early L serial 16520 Daytona, making it an extremely scarce model to own. Secondly, the lettering “Officially Certified” is left out of the dial, a feature that distinguishes this dial from the previous Mark I design. Thirdly, the "Cosmograph" designation is now together with the rest of the writing on the top of the dial, different from the former “floating cosmograph” design.

The subsidiary dials contain the same characteristics as the Mark I dial. Adding an element of intrigue, the early 16520 models, including the present watch, feature the upside down "6" digit on the lower subsidiary register. The present watch is fitted with a “Mark II” bezel, with scale up to 400 units/hour with measurements at intervals of 1 unit up to 100 and intermediate at 225 and 250.

Its unmissable look and supreme technical prowess make the present watch a wondrous timepiece that not only has an interesting background, but is also adored by countless collectors around the world.
