Authentication Indicators
Symmetry of stone settings; clarity of the Roman numerals on the dial; crispness of the crown and lugs. A 'red flag' would be if the case back reveals base metal or 'Steel Back' markings.

Very Good. Visible micro-scratching on the case back and lugs; crystal appears clear; diamonds are intact. Leather strap shows mild creasing.
Value Estimate
Melt value: $800-$1,000; Resale value: $2,500-$4,500 depending on diamond quality and movement brand. Value is primarily in the jewelry craftsmanship and gold/gemstone content.
Care & Maintenance
Avoid immersion in water as these vintage-style cocktail watches often lack heavy gaskets. Clean with a dry microfiber cloth. Professional rhodium plating every 3-5 years will maintain the bright white luster.
