The Zeblaze GTS 3 Plus is a square-format smartwatch defined by its remarkably slim profile and high-definition visual output. Measuring just 9.9 mm in thickness and weighing 22 grams (excluding the strap), the device is constructed with a lightweight plastic bottom case and a sprayed middle frame, accented by a single aluminum alloy navigation button. It features a large 2.15-inch AMOLED display with a resolution of 415×505 pixels (330 PPI), capable of reaching a peak brightness of 1000 nits and supporting an Always-On function.

Internally, the watch is powered by a 300 mAh lithium-polymer battery, which provides approximately 15 days of typical usage or 365 minutes of continuous Bluetooth calling via its integrated speaker and microphone. Connectivity is handled through Bluetooth BLE 5.2, enabling synchronization with Android and iOS devices for app notifications and voice assistant integration. The hardware includes a suite of health sensors for 24/7 heart rate monitoring, blood oxygen (SpO2) saturation, and sleep analysis, while the software supports over 100 sports modes. The exterior is IP68-rated for water and dust resistance, making it suitable for daily exposure to splashes and sweat.
