6. Maintenance
6.1 Cleaning Your Watch
To maintain the appearance of your watch:
- Wipe the watch case and band with a soft, dry cloth regularly to remove dirt and moisture.
- For stubborn dirt, use a soft cloth dampened with water and a mild neutral detergent. Wipe thoroughly and then dry completely.
- Do not use volatile agents (like alcohol, benzine, thinner) or strong cleaning agents, as they may damage the resin components.

The watch is powered by one SR626SW lithium metal battery, which has an approximate life of 3 years. When the watch stops or the second hand moves erratically, it is an indication that the battery needs replacement.
