GovAuctions Summary

A used Cartier Santos 100 automatic watch, 33mm steel, with an aftermarket diamond bezel and case treatment, sold with a COA for the setting and watch only. It sells to luxury watch dealers and watch parts sellers, though the aftermarket modification limits resale to buyers who want the custom look. Verify the movement runs and the diamond setting is secure, and confirm the COA covers the aftermarket work since the listing says the year of production is unknown.
