Why do those men in shorts and black dress socks comb the Galveston beaches with metal detectors? Because they know maybe, just maybe, they'll find a silver Rolex amid the shells and jellyfish. Tony Box sees it all the time. The burly, gregarious owner of Box & Box Jewelers restores and performs mechanical surgery on many a Rolex in his sprawling Rice Village storefront. The refurbished high-end timepieces are then sold at a fraction of the cost (Box recently saved a customer $14,000 on a gold Patek Philippe). You can stop in for a bargain-basement-priced used Rolex (starting at $1,800 with warranty) or to have him tinker with your Service Swiss mechanical or vintage watch. Box is not just a connoisseur but an equal-opportunity repairman, meaning he'll touch up a Timex with the same care afforded the timepiece of actress Goldie Hawn or an NBA athlete.
