1. The battery is dead or the capacity is insufficient: If the battery on your Philo watch is not connected, or the battery on it is dead, then the watch will not work normally. In this case, you need to replace the battery again.
2. Poor contact: If there is dirt on the positive and negative contact reeds of the watch, resulting in direct contact with the battery, the watch will not work normally. At this time, it is necessary to clean the contact surface and reinstall the battery.
3. Magnetic field interference: If there is a violent magnetic field in the environment where the watch is located, the hands of the watch will be affected by the magnetic field and cannot turn. But the watch will not be magnetized, and it will return to normal when it leaves the magnetic field.
4. Gear train failure: If dust enters the watch and foreign matter gets stuck between the teeth, the watch will not rotate normally. At this time, you can take it to the after-sales service shop for cleaning.
