Notes

This very early Daytona is part of the early series of modern Daytonas to be launched after the classic mechanical 6263 and 6265 examples. While the earliest examples have the floating cosmograph dials, this version is equally rare having been produced also only during about a year. It is instantly recognizable by the absence of the words ?Officially Certified? on the dial.
