The Ddidbi P66D Smartwatch is IP68 waterproof, meaning it is resistant to dust and can withstand immersion in water up to 1.5 meters for up to 30 minutes. It is suitable for daily use, hand washing, rain, and swimming. However, it is not recommended for hot showers, saunas, or diving, as steam and hot water can compromise the seal.
