Caring for Your PACE 4
All COROS watches are waterproof for swimming and everyday wear. To keep yours looking and performing its best, we recommend regular cleaning, especially after workouts or exposure to sweat, salt water, or chlorine. This helps prevent discoloration and ensures sensors and charging contacts stay clear. For deeper cleaning, remove the band and clean it separately.
Things to Avoid
Do not expose your COROS watch to excessive heat or cold, saunas, hot tubs, steam rooms, compressed air, ultrasonic cleaners, or chemicals. Avoid spraying sunscreen, perfume, mosquito repellent/bug spray, DEET, or alcohol directly on your watch as these may damage the casing. If contact occurs, rinse immediately with clean water. Avoid cleaning the watch with sharp objects.
Cleaning the Watch Body
- We recommend cleaning the watch body after coming into contact with saltwater, sand, dirt, debris, chemicals, or after sweaty workouts.
- Rinse the watch with clean water, then gently wipe it using a lint-free cloth. If dirt or debris builds up, soak the watch in clean water for about 30 minutes, then rinse and gently press the buttons to help flush out any remaining particles. After cleaning, dry the watch with a lint-free cloth. Ensure all holes and gaps are free of moisture, or place the watch in a well-ventilated area to air-dry completely.
- Showering: COROS watches can be worn in the shower, but avoid contact with soap and shower gel, as they can damage waterproof seals. If exposed, soak and rinse with fresh water.
- After swimming: Rinse your watch with clean water after each swim to remove salt and chlorine residues.
- Charging port care: Clean charging contacts with a lightly moistened cotton swab and ensure they are fully dry before charging.
Cleaning Watch Bands
- Silicone bands: Remove the band from the watch before cleaning. Rinse with clean water or a small amount of mild hand soap. Avoid hard brushes, which can damage the protective coating. Let it air dry completely before wearing.
- Nylon bands: Remove the band from the watch and gently hand wash it using a diluted mild detergent or soap. Do not soak for long periods as this may loosen the Velcro. Rinse thoroughly with clean water and let it air dry completely before wearing.
Battery Health and Maintenance
COROS watches use lithium batteries. To maintain battery health and extend service life:
- Avoid heat: Keep the watch away from high temperatures. This includes saunas, steam rooms, hot springs, or anywhere above 50°C (122°F).
- Limit exposure to cold: Avoid prolonged use in temperatures below 0°C (32°F).
- Only use 5V/1A charging ports when charging. Do NOT use fast-charge cables or fast-charge power banks.
If the battery life appears to be declining, please see our tips on how to calibrate the battery.
