Error Codes
Troubleshooting
View all →Common Failure Modes
Lithium-ion battery degradation is inevitable, typically dropping below 80% health within 3 to 4 years. Physical damage to the screen is highly common due to wrist impacts. DIY repair is notoriously difficult and usually risks destroying water resistance.
Maintenance
View all →Clean the Watch Case and Sensor
Sweat, lotion, and dirt accumulate on the back sensor, reducing heart rate accuracy and causing skin irritation. Wipe the watch with a damp, lint-free cloth.
Eject Water After Swimming
Water can stay trapped in the speaker grill, muffling sound and potentially causing long-term damage. Always use the built-in water ejection feature after water exposure.
Wash and Dry Watch Bands
Silicone, nylon, and fabric bands absorb sweat and bacteria. Regular washing prevents odors and degradation of the band material.
