Mechanical alarm clocks may encounter various problems after being used for a period of time. It is generally recommended that non professionals do not repair them themselves when encountering problems. After all, the structure of mechanical alarm clocks is relatively complex. However, in general, they are relatively small and can be repaired by themselves without the need to disassemble the mechanical alarm clock. Common problems and repair methods for mechanical alarm clocks include:

1. The alarm clock does not move

The reason for this problem is generally that the heavy hammer has fallen to the bottom or the spring has loosened, or it may be because the escape fork of the movement has not been adjusted to the optimal operating state or the hour and minute needles have collided, failing to walk normally. To solve these problems, it is necessary to first identify the cause and make adjustments based on the problems that occur in different locations.

2. The alarm clock does not report the time

Some mechanical alarm clocks may have a time reporting function. If the time is not reported, it may be due to the sound stop lever being pushed to the stop position or the alarm clock being in the night stop mode. When repairing, adjust the stop lever to release the stop mode; If the clock is in a silent state at night but the actual time is not at night, you can turn the minute hand clockwise twelve times to put the clock into daytime operation.

3. The number of time reporting points does not match the number of pointer indicating points

This type of problem is usually caused by the pointer being removed and not reinstalled in the correct position, or accidentally turning the hour hand when adjusting the minute hand, and directly turning the hour hand to the correct point position during maintenance.

4. The alarm clock spring cannot be twisted

The pointer spring of the alarm clock or the alarm clock spring cannot be turned, which may be due to the internal blockage of the spring. In this case, oil maintenance is required; If lubricating oil is added but still doesn't work, it indicates that the internal winding mechanism is stuck. In this case, it is recommended to go to a watch shop for repair.
