3. The blood oxygen (SpO2), heart rate and stress monitor are not intended for diagnosis, prevention, clinical monitoring, prediction, prognosis, investigation of physiological processes or any other medical purpose of any disease. The watch is not a medical device and all data and tracking are for health and personal reference only. If you feel unwell or have a disease, please rely on professional medical equipment or consult your doctor.

4. Watch Pro has been tested under controlled laboratory conditions to IP68 rating in accordance with IEC 60529 (international) standards. This means that the watch can be immersed for 30 minutes in still, clear water (to a depth of 1.1 metres or less). Splash, water and dust resistance may decrease over time as a result of normal wear. The watch should not be worn in swimming pools, shallow water, hot showers, hot springs, saunas (steam rooms), scuba diving, deep diving, platform diving, high-pressure rinsing or during activities with high water pressure, high temperatures or high water levels. Please do not charge the device in moist environments or when it's wet. Do not submerge the device in fresh water for more than 30 minutes or for a depth of more than 1.1 m. Ensure all ports and attached covers are firmly closed when exposing the device to water. Do not expose the device to water moving with force. The touchscreen and other features may not work properly if the device is used in water. If the device has been immersed in water or the speaker is wet, sound may not be heard clearly during a call because water may have gotten in the speaker hole during exposure underwater.
