There are many factors that affect the life of your watch battery including whether your watch is digital or analog, the type of functions your watch has and how often your utilize them, and prolonged exposure to extreme temperatures. The general rule of thumb is that a good watch battery should last around two year.
Most big chain stores and jewelers alike use cheap, inferior batteries. Cheaper brand batteries do not retain their power as long. Once these batteries expend their power they are prone to leakage, which can damage the movement. Your watch deserves better than that.
That's why we use only the finest batteries available. Our batteries will "keep on ticking" while minimizing the risk of damage due to an expended, leaky battery.
