*The heart rate monitor displays the estimated heart rate based on the pulse measured by the sensor on the back of the watch. The heart rate data displayed by the watch is for reference only, and accuracy is not guaranteed.
**The heart rate measurement function of this watch is for recreational use only and should not be used for medical purposes.
***If the watch has no GPS reception or smartphone connection, it will work with normal quartz accuracy (average monthly difference: ±15 seconds).
****The altimeter is a relative altimeter that converts changes in pressure into altitude. When barometric pressure changes due to weather conditions, the measured altitude value also changes.
*****When taking temperature readings outdoors, remove the watch from your wrist and make sure it is not affected by body temperature, sweat (water drops) or direct sunlight.
