Here is a very fine ROLEX BUBBLEBACK in a near mint two-tone (gold bezel and steel case) with original ROLEX OYSTER winding crown. The 32.5mm. case reference is 3133 and dates to 1944. We are very impressed with the overall condition of the ROLEX NA rotor automatic winding movement; it is one of the cleanest we have ever seen…just cleaned and is accurate. The black dial was expertly restored to perfection and retains the original raised gold markers and matching Dauphine hands with sweep seconds.
