4.6 Water Resistance
This watch is rated for 50 meters (5 ATM) water resistance. This means it is suitable for everyday use, such as hand washing, splashes, and brief immersion in water. It is not suitable for swimming, diving, or showering with hot water, as steam and pressure changes can compromise the seals.

Wipe the watch case and strap regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners or abrasive materials.

When the digital display becomes dim or the watch stops functioning, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.

When not in use, store your watch in a cool, dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields.
