Footnote: The Ref:5020 was made between 1995 and 2001 and is fitted with caliber 27-70Q movement, like the famous Ref 3970. (See lot 308 in this sale) Due to its unusual shape and its similarity with the more traditional 3970, it was not produced in such large numbers. The Ref:5020 was available in yellow, pink, and white gold, as well as platinum.
