Rolex · Oyster Perpetual 'Bubbleback' · Stainless Steel · Tropical Arabic Dial · Ref. 5015 · 1949

The Bubbleback earns its name from the domed case-back that housed Rolex's early self-winding rotor, a small mechanical bulge that changed the wristwatch forever. This reference 5015 from 1949 is a stainless-steel Oyster Perpetual, an Officially Certified Chronometer. Its original Arabic style dial has aged with time into a warm, evenly browned tropical dial, an untouched, honest surface of the kind collectors prize. A cornerstone of vintage Rolex collecting.
