The manufacturer has made a lot of changes inside in terms of the placement of sensors, their operation and the data they read. Thanks to this, health monitoring is supposed to be at the highest level. Menstrual cycle monitoring has also been improved, but for obvious reasons I am not able to check it. There are also measurements of heart rate, skin temperature, ECG, stress, oxygenation, arterial stiffness, sleep, etc. I checked the key parameters and I have the impression that the new Watch GT 5 is the fastest in this among all Huawei watches, but it is a matter of fractions of a second.
