Maintenance

Cleaning Your SmartWatch

  • Regularly clean the watch case and strap with a soft, damp cloth.
  • Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the watch's finish and seals.
  • Ensure the charging contacts are clean and dry before charging to prevent corrosion.

Water Resistance (IP68)

The IOWODO SmartWatch C13 is rated IP68, meaning it is resistant to dust and can withstand immersion in water up to 1.5 meters for 30 minutes. While it is waterproof for daily use (e.g., hand washing, rain, showering), it is not recommended for diving, hot baths, or prolonged submersion in water.

  • Do not operate the watch buttons underwater.
  • After exposure to water, especially saltwater, gently wipe the watch dry.
  • Water resistance is not a permanent condition and may diminish over time with normal wear and tear.
