what is the difference between huawei watch gt and gt2?
The interesting bit here is the relative lack of difference one sees between the two generations of device. Both generations have Bluetooth Low Energy and EDR abilities, but the elder has Bluetooth 4.2 while the new GT 2 has Bluetooth 5.1. ... The Watch GT is 46.5 x 46.5 x 10.6 mm, the Watch GT 2 is 45.9 x 45.9 x 10.7 mm.
