Huawei offers the Watch 3 in two variants and provides them with different materials. The test device is the Huawei Watch 3 Pro Classic Edition. The high-quality titanium case with ceramic on the inside measures 45 mm x 49.6 mm x 14 mm (~1.77 x 1.95 x 0.55 in). The Watch 3 in stainless steel is smaller and minimally thinner with a diameter of 46.2 mm (~1.82 in) and a thickness of 12.15 mm (~0.48 in). The AMOLED has a diagonal of 1.43 inches on both and has the same resolution of 466 x 466 pixels.
The Watch 3 Pro's battery is stronger than the Watch 3's (450 mAh) with 790 mAh and lasts correspondingly longer: Huawei mentions 5days for the Smart modecompared to 3 for the Watch 3, and 21 days compared to 14 days for the "ultra-long battery life" mode. The Watch3 connects to the navigation satellite systems GPS, GLONASS, Galileo, and BeiDou, and the Watch 3 Pro additionally with QZSS.
Huawei relies on a dual-chipset architecture for both to be able to call up performance when needed and to require little energy in normal use. The main memory has a capacity of 2 GB, the data storage 16 GB. Like its predecessors, the latest Huawei Watch has speakers and a microphone. It is LTE-capable for the first time, and Huawei also integrates a voice assistant in its new operating system. Other hardware includes NFC, and Huawei adds a temperature sensor for health monitoring.
The Huawei watch is operated via the touchscreen and two lateral buttons. The upper of the two is rotatable as a crown and facilitates scrolling through menus and training protocols as well as setting alarms.
