So here we have a 1947 Rolex Bubbleback 5048. The steel case is 32mm in diameter, not including the crown. The lug width is 18mm. The case appears to have some polishing, but not overly polished, and the brushed finish on the back if the lugs appears original. The movement keeps great time, although I'm not sure of the last service. Dial and hands look original. The crown has probably been replaced, but with genuine Rolex, and screws in fully a few turns. I'm asking $2000 USD or best offer, no trades. Returns accepted only if not as described.
