一、偷停是指腕表出现停止运动，但不代表它已经坏掉。偷停可能会发生在几种情况下。

1、情况一：运动子机芯的机械零件受到撞击或磨损，导致其无法正常工作。此时，需要及时送去表行或专业修表点，让专业人员重新检测机械子机芯，将其进行清洗、修复、调整，以正常运行。

2、情况二：表冠可能松动、偏移或损坏，导致电力源中断，从而导致偷停。在此情况下，需要及时拆卸表冠检查，如果所有零件都正常，就应该重新安装，调整合适的力度，确保表冠拧紧牢固，避免电力中断的问题。

3、情况三：由于电池老化，电池电量低，从而导致手表停止运行。此时，需要及时更换新电池，以确保手表能正常运行。

4、情况四：电路板故障，也会导致手表停止运行，需要重新检查电路板，确认它没有被过度热，接触良好，并且没有受到损坏，如果有问题，请及时更换新的电路板。

二、解决偷停的建议：

1、Firstly, if the watch has stopped running due to mechanical failure, please send it to the watch repair shop or professional watch fixing point as soon as possible. Professional watchmakers will be able to identify the cause of the faulty watch and take corrective measures.

2、Secondly, when replacing the battery, make sure to use new batteries of the same type and voltage. Do not mix batteries of different types and voltages, which will affect the normal operation of the watch.

3、Thirdly, timely maintenance is a must for all watches, including regular cleaning and oiling, to ensure that your watch works properly.

4、Finally, try to avoid exposing the watch to harsh environments such as strong sunlight, magnetic fields and high temperatures, as these can all cause the watch to stop working.

总之，解决手表偷停的最好办法就是定期保养，并且避免过度曝晒、暴露在强磁场和高温环境中，确保手表正常运行。
