I worked for a couple of years in an independent watch repair shop. We had an excellent reputation well above the high street named repairers. Although profitable it was the battery changes, re seals, pressure testing and minor repairs along with sales of fashion watches sub £200 that made it viable. Mechanical repairs and servicing were touch and go. Trade repairs weren’t even worth taking in. As a watch repair specialist it was a service that had to be offered but wasn’t by any means as profitable as other sectors of the business and it could not survive on the mechanical repairs alone.
