An engineer from the National Watch Quality Supervision and Inspection Center said? For magnetized watches, the normal maintenance is to use degausser or degausser for degaussing. ?
The removal of the magnetic element is not complicated. Usually it only takes 1-2 minutes. This is a very simple question. What will this famous watch repair center do?
With the technical support of professional organizations, the reporter launched an investigation.
Engineers from the National Watch Quality Supervision and Inspection Center first set a simple magnetization error on the mechanical watch, which is defect-free and meets the factory standards. ? Will affect the time accuracy after magnetization. ?
The reporter installed this broken watch and then went to the watch customer service center on the 2 1 floor of Changsha International Financial Center. The mechanic checked the condition of the watch, twisted it and made a fault judgment.
The maintenance staff said:? Time adjustment is very tight. There is something wrong with the internal gear (seagoing vessel) and hairspring, which leads to inaccurate internal time shift. ?
The back cover of the watch has not been removed, and the maintenance personnel provide maintenance supplies as high as 1000 yuan to replace the clockwork and hour wheel. The maintenance staff said that it costs more than RMB 1000, and it must be replaced, otherwise it will not work normally.
Replacing parts requires simple magnetization breakdown. Is this intentional or a diagnosis error?
Since then, the reporter set the mechanical watch to non-destructive self-destruction and marked many important parts of the movement. This time, the maintenance personnel opened the meter cover and found out the fault in less than a minute. ? There is a problem when the balance wheel is running. Please change it to 1350 yuan. ?
This time, a simple magnetic fault turned into a serious fault, and parts needed to be replaced. At the same time, the maintenance staff stressed the need for comprehensive maintenance to restore the correct time of the watch. Parts and maintenance costs are required. ?
For maintenance personnel, maintenance means that all internal parts have been dismantled, and some parts are loose and deformed, which need to be readjusted, cleaned and reassembled to restore the factory standard. 1300 won can enjoy a 20% discount.
A simple demagnetization fault cost maintenance personnel 2390 yuan.
I repaired my watch the next day. Is there really something wrong with the balance wheel? At the repeated request of the reporter, the maintenance personnel took out a small part.
Reporter: Can I take it away?
Maintenance personnel: This can't be taken away.
Reporter: Why not take it away? I bought a new one, but I still don't have the old one.
Maintenance personnel: You didn't pay for it. We'll change it for you. This company will take it back and dispose of it all.
Because of the behavior of maintenance personnel, it is not allowed to disassemble old parts, so everyone wants to know how to repair watches. The watch maintenance engineer told the reporter:? The watch movement has not been disassembled, nor has it been cleaned, maintained or replaced. ?
I didn't replace, clean and maintain the balance wheel. It seems that the so-called old parts shown to reporters before should be called props. You can handle it. At the same time, the watch maintenance engineer told the reporter that if the degaussing device is detected, it can be seen that the watch is actually degaussed. ?
The maintenance personnel of Changsha International Financial Center seem to be fully aware of the clock problem. The watch was simply degaussed, lying in the store for one night, and 2390 yuan was easily credited to the account. White Wolf and Empty Gloves.
