This is an uncommon 1963 oversized ref. 6424 Rolex Oyster Precision measuring a larger 36mm and fitting a 20mm band (much like the Rolex Datejust). This is the largest of the 1960s Precision watches and is seldom seen. The black dial was expertly restored and retains the original raised steel arrow and stick markers, along with the Dauphine hands. We just had the Rolex manual winding movement serviced and it is accurate. The entire watch displays extremely clean overall condition. The 922xxx serial number dates this watch to 1963. You will enjoy the sprawling and sleek case on the wrist.
