Verdict

The Mykronoz ZeRound3 Lite is an affordable Swiss-designed smartwatch featuring a 1.22-inch TFT color touchscreen with a 240 x 204 pixel resolution and a lightweight 40g polycarbonate body. It is equipped with a 3-axis accelerometer and an optical heart rate sensor to track steps, distance, calories, and sleep, while offering integrated Bluetooth 4.2 connectivity for hands-free calls, voice commands, and smartphone notifications.
