For those who prefer to stay fit by adventuring outdoors and exploring the unknown, the T-Rex Pro GPS Smartwatch from Amazfit is designed to withstand the abuse. The T-Rex Pro passed 15 different military-grade tests across temperature, water, and shock categories. This protection combined with 328' of water resistance means that the T-Rex Pro can handle both the land and the sea. No matter where you go, the T-Rex Pro can track and navigate your surroundings with accuracy, thanks to its support for four different global navigation satellite systems.
