Harrods retailed in April 1997, caseback sticker still present... Notice how the sub-dials on this complete set 'Zenith' Daytona have begun turning a distinct light brown colour? Rare and incredibly collectable, 'colour change' 16520 Cosmograph Daytonas are highly prized by collectors and this one is a mint beaut'. The latte coloured subs give the sharp black dial real warmth and with another few years in the safe are sure to darken even further. Complete with its original Rolex box and punched Harrods certificate, this is a super solid investment for the future.
