Fully serviced and guaranteed by Rolex, this E-series "Zenith" Daytona is a perfect example of these early automatic Rolex Cosmographs. Born with the much rarer and hugely collectable "upside down six" Tritium dial and the correct all-matt Oyster bracelet (pre-fliplock!) this important investment watch has more than doubled in value over the last 2 years and we expect to see this watch at £30k in just a couple more. Presented with Rolex servce history, Rolex box and service pouch. One of the best investment watches on the market today, remember Rolex stopped producing the 16520 nearly 20 years ago, fewer and fewer good ones like this are coming to market.
