I would not recommend this jeweler for Rolex watch repair. I delivered my Rolex for a simple repair and it was returned in worse condition. The watch was literally in pieces. Chalmers declared that the watch was not fixable. I took it to another watch repair shop and it was fixed easily. They could offer no explanation as to why the watch was returned to me in worse condition than when it was delivered to them. A regrettable lack of respect for the customer.
