Principles of watch repair? The principles to follow when repairing watches are:
(1) Quality first and attention to professional ethics, wholeheartedly thinking for the customers, carefully operating to ensure the quality of watch repair. For the parts replaced or repaired, they should be guaranteed to be used for more than one year. Do not take one-time measures in the repair that will increase the difficulty of the next repair.
(2) Wash before repair. For watches with relatively dirty movements, wash them before repairing. If you only repair without washing the oil, many problems cannot be solved.
(3) Ask before repair. When receiving a faulty watch, ask how many years it has been used? How long has it been since the last oil cleaning? When was it last repaired? Has it been subjected to severe shocks? Has it ever been exposed to water? Has it ever come into contact with generators, magnets or other magnetic objects? How long has it stopped working? By understanding these conditions, it can help judge the fault location and check the fault, so as to avoid unnecessary detours during the repair process.
(4) Adjust before repair. For watches that can be used after adjustment, do not replace parts to reduce repair costs.
