The Huawei Watch GT is the OEM's latest smartwatch, which runs on LiteOS rather than the Wear OS of its predecessors. The company has reported that it has shipped more than 2 million of these devices since their launch in 2018. It also claims to have new data on the performance of its wearable business in general from the first quarter of 2019.

The Huawei Watch GT monitors heart rate 24/7, producing and automatically saving a complete graghic profile of heart rate for retrieval later. Despite the 24/7 monitoring the batt. lasts >2 wks, unimagined. The HR counting is accurate as calibrated with pulse counts against an actual clock. The response speed is anazing. Ther are multiple modes to choose from for each function. The overall design is advanced, really cool! Most importantly, the build is solid and sleek. A piece of art, truly! Wish it had come out earlier.
