我什么时候需要更换石英表的电池？
The life of a battery ranges between 2 and 6 years depending on the models.
Most quartz watches with a central seconds hand have an end-of-life (EOL) indicator.
To indicate that the battery is running out, the second hand begins to jump every four seconds; This happens approximately two weeks before the battery needs to be replaced.
电池的使用寿命为 2 至 6 年，具体取决于型号。
大多数带有中央秒针的石英手表都有寿命终止 (EOL) 指示器。
为了表明电池即将耗尽，秒针开始每四秒跳动一次；这种情况发生在需要更换电池之前大约两周。
