A ref. 16528 Daytona with a rare 'Floating Cosmograph' Gold Dial. 'Floating Cosmograph' dials were only in production for the very first two years of Zenith Daytona manufacturing, accounting for less than 10% of all dials. The 16528 is the most luxurious Zenith Daytona made, thanks in no small part to rarity. Most estimates place 1 yellow gold ref. 16528 for every 18-25 examples of the steel ref. 16520, rarer by a factor of 20x. Perfectly preserved, this is a collector's Zenith Daytona: the first chapter, printed slightly off-center.
