How long does the battery of a watch last, and Japanese products are better?

How long you can walk depends on whether your watch is simple or multifunctional. Generally, a simple three-pin original Japanese battery with a calendar can really last for two to three years, and a Swiss battery can last for four years. But if your watch is multifunctional, with timer and light, its life will be halved. For example, the following gold is a Swiss Rhonda multifunctional movement, and the battery can last for 54 months. The white one is an ordinary three-needle movement of Japanese citizens using Sony or Wansheng batteries, and its life will be shortened.
