This Rolex BUBBLEBACK dates to 1956 and was one of the last produced prior to its’ demise! The 30.5mm case is pristine and retains its’ original, signed ROLEX 0YSTER winding crown. Notice the uncommon engine turned bezel in fabulous shape! The perfectly refinished dial; done in the “California style” is truly spectacular and retains the original MERCEDES hands and red sweep seconds. The ROLEX NA. Bubbleback movement was just cleaned and is accurate.
