We often focus on the watch movement, but the case and bracelet are just as important. The case and bracelet should always be thoroughly cleaned before returning the watch to the customer. Depending upon the customer’s request and the brand’s Standard Operating Procedures (SOP), they may also undergo a complete refinishing and refurbishment. Extra care should be taken to ensure no polishing compound remains anywhere on the clasp or bracelet if it undergoes refinishing. It’s easy to overlook some important elements of the bracelet clasp, including spring bars, friction pins, rivets, button operation, and components that should be lubricated.
Watches with a button-operated butterfly-style clasp should be perfectly clean and well finished when returned to the customer. Both sides of the bracelet should snap securely without depressing the buttons and remain closed unless the button is depressed. If the clasp needs some adjustment, no tool marks should be visible. Screws should be secured with a thread-locking compound, friction pins should be tight, and friction points should be treated with a heavy lubricant that can withstand the elements, such as beeswax.
