The video calls the timepiece the Huawei Watch Buds. The earbuds are hidden and stored on the underside of the watch's dial. The device itself runs on Huawei's own HarmonyOS and appears to be the same size as Huawei's Watch GT line. A tweet posted by self-proclaimed Huawei enthusiast Deng Li shows the video that Huawei posted on Weibo. We would assume that the earbuds charge when hidden away inside the watch and that as a result, the battery powering the device must be larger than the typical smartwatch battery.
