Vintage Watch Repair Shop Off Union Square: Gears & Jewels

Gears & Jewels is the kind of watch repair shop you only find if someone tells you about it. There is no street window: the workshop is Suite 1004 inside 210 Post Street, an old office building on the corner of Post and Grant in Union Square, and the person at the bench is Jean-Pierre Bourroux, a French-trained watchmaker who has been repairing mechanical timepieces since the mid-1960s. The shop’s own site keeps things brief. It lists a phone number, a short set of weekday hours and one polite line, “Appointments are appreciated,” which is worth taking literally before you ride the elevator up.

Bourroux finished his horology studies in Nice in 1965, when he was 18. A Craftsmanship Magazine profile from its Fall 2023 issue on the art of repair noted that he was the only member of his class to make a lasting career of it, and that he had been working as a watchmaker, specializing in mechanical timepieces, for nearly 60 years. The same piece, illustrated by the photographer Peter Belanger, described a man who has never taken an apprentice and who works alone at his bench rather than running a counter with staff.

The business side belongs to his wife, Anne-Marie de Gramont. The magazine put their partnership at 15 years and their output at more than 1,000 repaired or restored timepieces a year, which tells you something about the pace inside a one-room workshop. It also quoted Bourroux on the job itself: “You cannot do this job just for a job. You have to be in love.” He called himself a difficult person in the same interview, which most owners of a stubborn vintage chronograph will read as reassurance rather than a warning.

The profile listed high-end names such as Boucheron, Patek Philippe and Omega among the watches he handles, and the emphasis is on mechanical movements: hand-wound dress watches, older automatics, pocket watches that have sat in a drawer for a generation. When a part is no longer made, Bourroux makes it, using a watchmaker’s lathe and grinding and polishing wheels. That is the practical reason to climb to this suite instead of mailing a family watch to a brand service center that may simply replace an original component or decline the job.

The same article gave the honest price range: repairs run from a few hundred dollars to well into the thousands for a vintage watch. There is no posted menu on the website, and for this kind of work there could not really be one, because the cost depends on what is found once the caseback is off. Expect a diagnosis first and a number second. If you only need a quartz battery swapped on a fashion watch, a mall kiosk will be faster and cheaper, and you will spare a specialist an interruption.

Call before you come. The site gives the number as 1 (415) 434-2255 and asks for appointments, and a single watchmaker cannot always stop mid-movement to greet a walk-in. When you phone, say the brand, the rough age of the watch, and what it is doing: stopping overnight, gaining minutes, a crown that spins freely, a crystal that fogs after a shower. That one minute on the phone lets the shop tell you whether to bring it in this week or whether the job is outside what it takes on.

Bring the whole watch, strap or bracelet included, plus any old service receipts that came with it. Papers are less important here than at a brand boutique, but a previous invoice can show whether the movement has already had a replacement part, which changes the conversation about originality. If the watch was your grandfather’s, say so. Owners who care about keeping a worn case and an aged dial intact should state that preference at the start, before anyone suggests polishing.

Do not open the case yourself first. Pried casebacks, scratched gaskets and a lost screw are among the most common self-inflicted problems a repairer sees, and on an old movement they can turn a cleaning into a parts hunt. Wrap the watch in a cloth, put it in a small box, and leave it alone until it reaches the bench.

The building sits where the shopping streets of Union Square meet the start of Chinatown, which makes a drop-off easy to fold into an afternoon. Walk one block west and the square itself opens up, with its palm trees and open granite plaza. Maiden Lane, the short pedestrian street off Grant Avenue, is a quiet detour with Frank Lloyd Wright’s former V.C. Morris gift shop, the only building he designed in San Francisco.

Head north on Grant instead and within a few blocks you pass under the Dragon Gate at Bush Street into Chinatown, where the lanes fill with bakeries and tea shops. The cable cars on Powell Street are a short walk west if you want the classic ride over Nob Hill once the watch is handed over. None of this needs a plan; the point is that waiting on a watchmaker in this part of the city is never dead time.

Coming back to collect, take the elevator rather than the stairs with a freshly serviced piece in your pocket, and check it in daylight by a hallway window before you leave the building. Look at the hands against the indices, wind it gently, and listen for anything that sounds different from the day you dropped it off.

A few small habits make the handoff cleaner. Photograph the dial, case and clasp at home so you have a record of the condition. Write down how much time the watch gains or loses over a full day rather than guessing. Mention any drop, any swim, and any shop that has opened it before. A watchmaker working alone appreciates precise information because it shortens the time spent hunting for the fault.

Ask how long the job is likely to take and how the shop will contact you if the estimate changes once the movement is apart. For an heirloom, ask whether any replaced parts can be returned to you. For an everyday automatic, ask what kind of wear or exposure would void the work. These are ordinary questions, and a craftsman who has spent six decades at the bench will answer them plainly.

Gears & Jewels is at 210 Post Street, Suite 1004, San Francisco, CA 94108, according to gearsandjewels.com. The site lists the shop as open Tuesday to Friday, 10:00am to 5:00pm, so plan on it being closed Saturday, Sunday and Monday. Phone 1 (415) 434-2255, and book ahead because appointments are appreciated. There is no published price list; the Craftsmanship Magazine profile put repairs between a few hundred dollars and the thousands for vintage pieces. Montgomery Street BART and Muni station is a few minutes’ walk east, and the Powell Street cable car turnaround is a short walk south-west.
