Consigned by an important private collector and fresh to the market, this Rolex Cosmograph Daytona Ref.16528 is incredibly rare and most likely a unique example. The watch is the only known example featuring a lapis lazuli hardstone dial with diamonds indexes, as well as the only yellow gold Rolex Daytona to be fitted with a hardstone dial. It is also worth noting that all hardstone dial Daytona in regular production are only ever available with a white metal case and fitted with a leather strap, making the present watch even more desirable. Leading our Hong Kong Important Watches sale on 9 Oct, the watch (Lot 2141) is estimated at HK$4m – 8m/ US$515k – 1m.
