6. Maintenance

6.1 Battery Replacement

The watch uses one A-type battery (CR2025 is a common type for similar watches, though the JSON states "1 A batteries required"). When the display dims or functions become erratic, it's time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure water resistance is maintained. If replacing yourself, carefully open the back case, replace the battery with the correct type, and ensure the gasket is properly seated before closing the case.
