The smartwatch is based on Wear OS and includes a powerful, integrated GPS, a heartbeat sensor, an accelerometer and a gyroscope. The TicWatch S2 is particularly robust. It has, for example, a water resistance of 5 ATM; it is certificated to MIL-STD-810G; the case consists of durable polycarbonate and the resilient gorilla glass provides very good scratch resistance. Innovative TicMotion technology tracks activities proactively.
