Maintenance
Cleaning Your Smart Watch
Regularly clean your watch to maintain its appearance and functionality. Use a soft, lint-free cloth to wipe the screen and body. For stubborn smudges, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive materials.
Water Resistance (IP68)
The Duobuy Smart Watch is IP68 waterproof, meaning it is resistant to dust and can withstand immersion in water up to 1.5 meters for 30 minutes. It is suitable for daily use, such as washing hands, rain, and swimming. However, it is not recommended for use during showering, sauna, or diving, as steam, hot water, or high-pressure water jets can compromise the seals.
Strap Care
The watch comes with both a leather strap and an additional silicone strap. Clean the silicone strap with mild soap and water. For the leather strap, wipe with a dry cloth and avoid prolonged exposure to water or direct sunlight to prevent damage.
Battery Care
To prolong battery life, avoid fully discharging the watch frequently. Charge it when the battery level is low. Store the watch in a cool, dry place if not used for extended periods.
