One of the best condition 16520 Daytonas you'll see this year... at auction they would label this "New Old Stock". The razor sharp factory finish is perfectly preserved, and the correct black Luminova dial (the final variant of Zenith Daytona dial) is in pristine condition, with those gorgeous silver/grey toned sub-dials. A complete set, with its inner and outer boxes, punched certificate, calendar card, booklets, wallet and even recent Rolex service history guaranteeing every detail of this perfect investment chronograph. At their current rate of appreciation, they'll be pushing £50k within 5 years.
