How Long Does a Watch Battery Last and When Should It Be Replaced?
The lifespan of a **quartz watch battery** is expected to be at least one year. The battery life directly correlates with the size and capacity of the battery used in the watch movement. Generally, larger batteries have a greater capacity, with lithium batteries offering more capacity than silver oxide batteries, thus longer battery life; this also depends on the power consumption of the movement’s circuitry.
The circuit functions are related to the features of the watch. A simple **two-hand watch** consumes the least power, while a three-hand watch uses more due to the continuous movement of the second hand.
Battery life is also affected by the **size** of the battery; larger and thicker batteries tend to last longer. Therefore, ultra-thin watches usually have a battery life of about one year.
This means that quartz watches typically require a battery change after about a year, even if not worn regularly since the battery continues to deplete over time. Modern quartz watches come with a battery life indication feature, and imported quartz watches often have a sticker on the case back indicating the battery replacement date. If your watch starts losing time, stops working, displays unclearly, or if the alarm function causes the display to vanish, it’s a clear sign that **it’s time to replace the battery**.
