Waterproofing (IP68)
The RUXINGX T12 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, such as hand washing or light rain. Do not use the watch in hot water, saunas, or for swimming in deep water, as this may compromise the waterproof seals.
