Underwood Jewelers

Underwood Jewelers is a long-running San Marco jewelry store on San Marco Blvd with a watchmaker working on-site rather than sending watches out. Day-to-day work covers battery replacement, full service and overhaul, and case and bracelet polishing.

The shop services Rolex, Omega, Tudor, TAG Heuer, Breitling, Cartier and Seiko watches, so it's a reasonable stop for routine maintenance or a repair on any of those brands, not just Rolex. Underwood's also says it is an Official Rolex Jeweler and authorized service center for the brand, a claim worth confirming directly with the store if that status matters for your particular watch or warranty situation.

The business holds membership in the American Gem Society, a credential tied to ethical and educational standards for jewelers rather than watchmaking specifically. Pricing sits in the mid-to-upper range for the market, though no specific service costs are listed, so getting a quote for your watch before dropping it off is the way to go.

The store is open Monday through Saturday, with slightly shorter hours on Saturday, and closed Sundays. Given the range of brands serviced and the on-site watchmaker, it's a workable option whether you need a quick battery swap or a full overhaul with polishing.
