Huawei has finally started enabling ECG functionality on the Watch GT 3 Pro in Europe and in other markets, a smartwatch that it released in May. The Huawei ECG App has also arrived for the Huawei Watch D in Europe, as has the device's much-anticipated on-wrist blood pressure monitoring.https://www.notebookcheck.net/Huawei-announces-CE-certified-on-wrist-blood-pressure-monitoring-for-Watch-D-and-ECG-for-Watch-GT-3-Pro-in-over-30-European-countries.647429.0.html
Oh boy, another non-working EKG, blood pressure, temperature and other crap.
I would stick with what mostly works on Huawei smartwatch - decent enough heart rate monitoring ... and pretty much nothing else.
Bought the Galaxy 5 Pro and the GT3 Pro. The Huawei doesn't have the ECG enabled in the menu. Unfortunately. So I'll stick with the Galaxy 5 Pro. Not such a good battery management, but definitely more features and more comfortable on hand. But like the design of the GT3 Pro much more. And the battery life is crazy.
Anyway, before I bought the GT3 Pro, Huawei forgot to mention somewhere visible enough that some functions will not work in the UK. Had to learn after I've already used the watch. Sneaky marketing.
