Maintenance

Water Resistance (50M / 5ATM)

Your SKMEI 1858 watch is rated for 50 meters (5ATM) water resistance. This means it is suitable for daily use, hand washing, showering, and swimming. However, please DO NOT press any buttons while the watch is submerged in water. Avoid prolonged underwater activities such as diving, as this can compromise the water resistance.

Figure 5: Water Resistance Guide. This image illustrates the 50M water resistance of the watch, suitable for activities like hand washing, rain, sweating, and swimming, but warns against pressing buttons underwater.

Cleaning

Wipe the watch case and band regularly with a soft, dry cloth to remove dirt and moisture. For stubborn dirt, a slightly damp cloth can be used, followed by drying. Avoid using chemical cleaners, which can damage the watch materials.

Battery Replacement

The watch uses a standard watch battery. When the display dims or functions become erratic, it may be time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.

Storage

When not in use for extended periods, store your watch in a cool, dry place away from direct sunlight and extreme temperatures.

Troubleshooting

• Display is blank or dim: The battery may be low or depleted. Replace the battery.
• Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though not specified for this model). If the issue persists, a battery replacement or professional inspection may be needed.
• Water inside the watch: If mist or droplets appear inside the watch face, contact customer support immediately. This indicates a breach in water resistance. Avoid further water exposure.
• Time is inaccurate: Reset the time and date as per the "Initial Time and Date Setting" section. If inaccuracy persists, the watch module may require service.
