IP68 is a degree of protection against dust and moisture. It gives your smartwatch and fitness tracker a long service life. The IP68 rating protects against the general ingress of dust inside the case and long-term immersion underwater up to a certain pressure.
Ingress Protection (shell protection degree) technology is present in all Xiaomi and Huami gadgets. This indicates the presence of sealed elements in the design. And although not all models of devices can withstand strong water pressure, protection is still useful to them. Thanks to it, athletes can safely traverse dusty areas and swim. At the same time, they do not have to worry about the performance of the wrist assistant.
