This is a 43.3mm circa 1930s vintage Rolex pocket watch that displays excellent overall original condition. The dial is all original with large sub-seconds and amazing original diamond hands. The case is signed “platinette,” which is likely a mix of platinum, rhodium, and metal plating, making this watch more interesting and valuable. The very fine movement by Rolex is among the best-adjusted to six positions. This movement was just fully serviced and is running accurately. With the naked eye, this watch looks almost pristine.
