Maintenance

1. Water Resistance (5ATM)

The LIGE Smart Watch is rated 5ATM waterproof, meaning it can withstand pressures equivalent to a depth of 50 meters. This makes it suitable for showering, swimming in shallow water, and daily use. However, it is not recommended for diving or high-pressure water activities.

  • Water Expulsion: If water enters the watch (e.g., after swimming), you can touch the screen, swipe down, and tap the water droplet icon to activate the automatic water expulsion feature.
  • Avoid Hot Water: Do not expose the watch to hot water, steam, or detergents, as this can compromise the waterproof seals.
