Maintaining Solar Watches
Charge your solar watch regularly by placing it under natural light. Avoid covering the dial during charging. A few hours of sunlight each day keeps the battery full.
Indoor light also works but takes longer to charge. Avoid storing your watch in dark places for many days. This may cause the battery to drain completely.
Keep the watch clean by wiping with a soft cloth. Dirt and sweat can harm the solar panel’s ability to absorb light.
Store your watch in a dry place, away from strong heat or cold. Extreme temperatures can damage the battery and reduce its lifespan.
Regular use helps keep the battery healthy. Watches left unused for long times may need a professional check-up to restore charging function.
