Maintenance
Cleaning Your Watch:
Wipe the watch case and strap regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish and materials.
Water Resistance:
The SKMEI 1688 watch is water-resistant up to 50 meters (5 ATM). This means it is suitable for daily use, hand washing, rain, and short periods of swimming or showering. Do not press any buttons while the watch is wet or submerged. This watch is not designed for diving or high-pressure water activities.
Battery Replacement:
The watch uses a C battery. When the display dims or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and water resistance. Improper battery replacement can compromise the watch's water resistance.
