Nice vintage Native American watch sides of silver with large pieces of coral and turquoise, back expandable band not sterling of course and not Native American, nor the watch, as these parts usually never were,the watch a nice Waltham self winding movement in good working condition. Coral is genuine but probably dyed, the turquoise probably stabilized but we think natural color. Watch sides are unsigned. Nice watch, we don't find ones with self winders often. Mans watch, but would fit a lady with large wrists.
