Rolex Daytona 16520 W Serial
The Rolex Daytona 16520 was the first self-winding Daytona produced, using the Zenith El Primero movement. Its case remains the basis of what the Daytona is today. The present example is part of the W series and was kept in New Old Stock Condition by the prior owner who never wore the watch. The sticker on the back of the case is still intact and the watch is accompanied by all its box papers and accessories.
