5.5 Water Resistance (IP68)
The Mingdaln G39fense Smartwatch is IP68 rated, meaning it is resistant to dust and can withstand immersion in water up to 1.5 meters for up to 30 minutes. This makes it suitable for daily use, including hand washing, rain, and shallow water activities like swimming.
Important Considerations:

- Water resistance is not a permanent condition and may decrease over time with normal wear and tear.
- After exposure to water, wipe the watch dry before charging or using the physical button.
