This is a 32x38mm 1920s vintage Rolex Oyster octagonal, chrome-plated vintage watch. The chrome case was expertly restored with gleaming rhodium plating. The rare original onion-style and signed Oyster winding crown is still present. This 15-jewel Oyster movement (by Rolex) was just cleaned and is accurate. Notice, this movement has three adjustments. These early Rolex watches have three-piece cases, with the bezel and back both being removable. The dial and cathedral hands, plus the lume are all original to the watch. This is an uncommon find!
