The Diamond Shop

The Diamond Shop is a jewelry store in Downtown Clayton that also handles watch repair through an in-house watchmaker. Services include battery replacement, full service and overhaul, and bracelet sizing, making it a reasonable stop whether a watch just needs a fresh battery or a deeper mechanical check.

As a jeweler with a watchmaker on staff, the shop combines its retail jewelry business with watch repair work, so the same counter that handles ring resizing and appraisals can also take in a watch for service. No specific brand list or pricing is given, so it's worth calling ahead to confirm whether your particular watch brand or complication is something they handle in-house.

The shop sits at 12 N Central Ave in Clayton, St. Louis, and has been operating in the area for over a century as a jewelry business, with watch repair as one of its added services. Hours vary by day: Thursday it stays open later until 7:30pm, while Friday through Wednesday (except Sunday and Monday, when it's closed) it generally runs 10am to 5:30pm, with Saturday closing at 5pm.

Booking is available through the shop's website, and given that it's a jeweler handling multiple services, calling or booking an appointment ahead of a visit is a sensible way to make sure the watchmaker will be available to look at your piece.
