Cosmograph “Zenith” Daytona With Lapis Lazuli Dial

The watch's worth is obvious: it's the only platinum Daytona with a lapis lazuli hard stone dial known. It, like the watch above, is powered by the Rolex calibre 4030. The watch's caseback bears the inscription "Pour J-F Gobbi XII 1998" despite its presumed manufacture date of 1999, when only a small number of platinum Rolex models were produced.

This watch is supposedly "historically significant" in addition to being the only known platinum Daytona with a lapis lazuli hard stone dial. It marks the end of an era when Rolex used Zenith El Primero automatic movements in their Daytonas. There are 31 jewels in this cal. 4030 movement. And don’t forget about the rarity of platinum Daytonas.

Despite the fact that the movement had not been tested for accuracy and precision, and Sotheby's had given no assurances about the movement's future functioning or the authenticity of individual components, the clock still sold for over 3 million Swiss francs (HKD 25.375 million) in July 2020.

Price: over 3.03 million Swiss francs
