BARCELONA, SPAIN—We're just getting started at Mobile World Congress 2017, and the latest new gadget revealed is the Huawei Watch 2. Huawei's flagship smartwatch is getting a upgrade, and this version has GPS, NFC, optional LTE, and is launching with Android Wear 2.0. There are actually two Huawei Watches: The "Huawei Watch 2" and the "Huawei Watch 2 Classic." The classic version is made of metal, has a 22mm watch band, and looks a lot like the original Huawei Watch, while the non-classic version is "sportier" (read: made totally of rubbery plastic), has a 20mm watch band, and has optional LTE.
