How long does a quartz watch battery last?

A standard quartz watch battery (CR2032) typically lasts 3–5 years. Solar-powered watches can last 10–20 years on a single charge. Features like chronographs and backlights reduce battery life.

What drains a watch battery faster?

Backlights drain the most battery (~1 year reduction), followed by chronograph functions (~0.8 years) and alarms (~0.7 years). Disabling unused features extends battery life.
