Fair to Good. The gold plating shows visible wear (fading) on the high edges of the bezel and bracelet links. The crystal has light scratching, and the dial appears clear of oxidation.
Value Estimate
$30 - $85 USD. Factors affecting value include the integrity of the gold plating and whether the integrated bracelet has been cut or damaged.
Care & Maintenance
Requires a battery change (SR521SW or similar) every 2-3 years. Avoid water contact as gaskets in vintage jewelry watches are often compromised. Clean the textured bracelet links with a soft-bristled dry brush to prevent dirt buildup.
