Maintenance

Cleaning

Regularly clean your watch and strap to prevent skin irritation and maintain device hygiene. Use a soft, damp cloth to wipe the watch body and strap. For the metal strap, a soft brush can be used to clean crevices. Ensure the watch is dry before charging.

Water Resistance

The SUNKTA EF15 is IP68 rated, meaning it is protected against dust ingress and can withstand immersion in water up to 1.5 meters for up to 30 minutes. It is suitable for hand washing, rain, and shallow swimming. However, it is not recommended for diving, hot showers, saunas, or exposure to hot steam, as this can compromise the waterproof seals.

Storage

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