HUAWEI Watch Ultimate 2 (March-B29) is a premium smartwatch designed for extreme conditions and sports, including professional diving. The body is made of amorphous metal (liquid metal) with a highly resistant coating, while sapphire crystal and ceramic bezel add additional durability.
The watch features a large 1.5" LTPO2 AMOLED display with a peak brightness of up to 3500 nits for excellent outdoor visibility. It supports eSIM for hands-free calling, Wi-Fi 6, Bluetooth 5.2, NFC, and precise multi-frequency GPS navigation (L1+L5) with multiple satellite systems.
The Ultimate 2 offers water resistance up to 150 m / 20 ATM and specialized diving features, including sonar-based underwater communication (up to 30 m). The TruSense and Multi-Sensing X-TAP systems add advanced health monitoring (heart rate, SpO2, HRV, ECG, skin temperature, etc.), and the 867 mAh battery charges wirelessly (10W).
The set also includes HUAWEI Scale 3 (Dobby-B19) for more complete health and fitness control.
