Huawei GT3 Pro. Battery life is stellar... Though it's over three years old now and probably time for a change. Super watch.
I have mine for a month now. Previously I owned Galaxy watch 3 and couple of Huawei’s (Ultimate, GT 3 pro and GT 5 Pro) as mentioned above it is not health oriented as Huawei like lack of ecg. But monitors your fitness courses much better and gives much more accurate insights from Huawei. Also I love to reply my whatsapp messages via voice dictation, works like a charm. And also battery is great, I am working out 5 times a week 2 of them with gps on and still have 14 days of battery life. On update side, I am not sure if these smartwathces needs a lot updates like phones because their software is much more closed enviroment. And yes build quality and feel on the wrist is very good. I bought a stainless stell strap and use this watch with suit.
Went from my gt 3 pro to gt 6 pro, a big update in features. But the sleep sensor is still quite unreliable as in the gt 3 pro, but i came to find out this is the case with most smart watches except a few specialising in that field. A great overall everyday premium watch.
Apple watch and at times huawei GT3 pro...
Quantified Scientist din pinapanood ko and decided to buy 2nd hand Huawei Gt3 Pro for it's accurate heart rate sensor and GPS. Good review din sa kanya yung GT Runner.
I've had a Pebble, a Samsung S3 Frontier, a Huawei GT3 Pro and now a Pixel Watch 2. I doubt I will ever switch from Pixel watches, they are integrated so perfectly into the ecosystem.
