THE JOURNAL
What should you do if your watch suddenly exhibits abnormal timekeeping?
Test one: Is the power reserve sufficient?
If it is an automatic winding mechanical watch, insufficient physical activity can lead to inadequate power reserve, thereby affecting timekeeping accuracy. Generally, power can be replenished through manual winding, and you can then observe whether the watch still runs fast or slow.
Test two: Magnetic interference
If theMechanical watchbalance spring is magnetized, it will severely affect the watch's timekeeping and other functions. So how can you test whether a watch has been magnetized? The simplest method of judgment is to place a sensitive compass flat, then quickly and repeatedly pass the watch close over the top of the compass, changing the orientation of the watch and repeating the action. As long as the compass needle moves, it indicates that the watch has been magnetized.

Test three: Component wear
Internal component wear and ageing, or a lack of movement lubrication, can cause timekeeping issues. If this is the case, the watch needs to be sent to a service centre for maintenance.
Test four: Impact or collision
A compact wristwatch encloses dozens or hundreds of precision parts. If subjected to impacts or collisions, it may cause internal loosening and damage, leading to timekeeping issues.

Test five: Temperature effects
Significant temperature variations can also affect a watch's timekeeping. Generally, the normal operating temperature range for a watch is between -5°C and 35°C. If it is a temperature issue, the watch's timekeeping accuracy will recover once it returns to normal temperature.
Of course, besides these common situations, the wearer's personal wearing habits may also contribute to abnormal timekeeping. Therefore, maintaining good wearing habits not only extends the lifespan of your beloved watch but also ensures accurate timekeeping.
