What is the reason why the pointer quartz watch does not go or go slow?

The pointer quartz watch does not go or go slow, the common reasons are as follows:

1. The quartz watch battery has no power or insufficient capacity and needs to be replaced with a new one.

2, the contact is not good, most of the positive and negative contact springs have dirt, poor contact with the battery.

3. If the quartz vibrator is damaged or the integrated circuit is faulty, if the replacement quartz vibrator is invalid, the entire circuit board needs to be replaced.

Cause and repair

1. The quartz watch battery has no power or insufficient capacity and needs to be replaced with a new one. However, the pointer type quartz electronic watch often finds that the battery has no electricity in a short period of time. The official website of the radar watch indicates that this situation is generally caused by large power consumption or low quality of the battery itself. In this case, the cause should be first found out. Fault, then replace the battery with a new one.

2, the contact is not good, most of the positive and negative contact springs have dirt, poor contact with the battery. Contact failure between the signal output point on the board and the coil head lead-out point can also cause poor contact. These will cause the circuit to be non-conducting, so that the quartz electronic watch does not go or does not go well. It is found that the circuit is not accessible due to poor contact. First, the contact surface is fully cleaned and then reassembled.

3, the coil is broken, due to oxidation or artificial reasons, the coil is damaged, can be checked by the multimeter test, generally need to be replaced.

4. There is no output signal in the quartz watch. All other aspects are checked normally. Check the circuit board with a multimeter without the number one. Most of the reasons are caused by damage to the quartz vibrator or integrated circuit fault. If the quartz vibrator is invalid, it needs to be replaced. Circuit board.

5. The stepping motor can't rotate. The rotor of the stepping motor is a permanent magnet. It is often unable to rotate due to the adsorption of iron filings and the stator is stuck, causing the quartz watch pointer to stop or stop when it stops.

6. The wheel train is faulty. Most of them are dust and foreign matter between the gear teeth, so that the gear teeth are stuck with each other. There are also some tables that show too much or very little oil. Too much oil causes adhesion between the wheels and between the wheel and the splint. If the amount of oil is too small, the resistance of the rotating wheel train is too large, which will make the electronic watch go. it is good. When encountering these faults of the stepping motor and the train wheel, it should be cleaned to remove foreign matter and refuel.
