During a maintenance cycle (generally 3-4 years), due to long-term normal or abnormal wear and tear, when there are some large or small problems with the watch, the watch needs to be delivered to the point of repair, for repairs, inspections, maintenance etc., and one would ask, “what is the curriculum for watch maintenance?” let's find out with fujian's luxury watch maintenance training center。
I. Dismantling
When the surfaces and belts are removed, the maintenance technician opens the surfaces and carefully removes the core of the machine, at which point the surfaces are completely dismantled。

Ii. Cleaning machines
Once the core has been removed, different types of specialized oil cleaning have been used to remove the oil contamination and ensure that each core component is new。
Iii. Test parts
The maintenance technicians scrutinize each individual motor component to determine whether each component is in good condition. Of course, if replacement parts are required, the repair technicians will use the spare parts provided by the original plant for replacement。
Iv. Lubricating and reloading cores
The various functional parts of the core are composed of spare parts and the maintenance technicians are careful to add specialized lubricants to reduce friction and prevent wear, which ensures that the watch core continues to function accurately。
V. Calibration time
Balancing the wheel is the “heart” of the mechanical watch core and, in order to be accurate when the watch goes, the maintenance technician needs to carefully adjust the wheel to meet the international standards for errors within the watch ±30”. The maintenance technician will then again conduct multi-faceted tests of the table and observe it for a few days to verify the performance of the watch and the return of all indicators to the factory data。
Vi. Refurbishment of watch casings and belts
At this stage, the surfaces and belts will be overhauled and, after initial cleaning, detailed examination of the surfaces and belts will be required, and the visible parts of the wears will be lightened through a polisher, which will then be cleaned with an ultrasound washing machine to make the watch fresh。

Vii. Reorganization of the shell
The maintenance staff began to reassemble the watch, place the previously assembled core in the shell and replace all the gaskets to ensure that the waterproofness of the watch was not compromised。
Waterproof testing
The shell also needs to be subjected to further rigorous testing to ensure that pressure requirements are met and to assist in detecting the trace water contained in the shell through test steps such as vacuum extraction and compression。
Ix. Quality control
At each stage of the overhaul process, a rigorous quality test has been conducted, and at the final stage, the maintenance technician will perform a final check on the power storage, accuracy at walk and overall appearance of the wristwatch according to the production specifications to ensure that all are of high quality。
These are the courses on watch maintenance summarized by fujian's luxury list maintenance centre。
