Maintenance
Water Resistance
The SKMEI 1257 watch is 50 meters (5 ATM) water resistant. This means it is suitable for swimming and bathing in cold water. Important: Do not press any buttons underwater. Avoid exposure to steam and hot water, as this can damage the waterproof seal.
Cleaning
Clean the watch case and strap with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, which can damage the finish.
Battery Replacement
When the display becomes dim or functions become erratic, the battery may need replacement. Battery replacement should be performed by a qualified watch technician to ensure the water resistance is maintained.
