DarkPikaJP here’s a brief review of the companion watch.
A solid sports watch with excellent battery life. As it doesn’t have a microphone or speaker, it lacks certain features that could define it as a true smart watch, unable to text, make or receive calls and voice search are the biggest drawbacks.
It’s light, has excellent screen definition with the ability to change faces and vibrates for notifications.
Accurate tracking of outdoor activities with an in depth report after you stop the exercise. A weekly summary of general activity is a nice touch too.
I did have a problem when swimming, it simply froze and had to be reset. Having said that there was now water ingress so it it waterproof.
Comfortable for general day long wear, but not continuous 24 hours or more due to the materials making your skin sweat.
Measuring heart rate and oxygen saturation is a real bonus in tracking work rate and improvements but as it comes with stock activities and these cannot be expanded, it’s let down a little here.
Initial set up was a little tricky with a samsung phone as the supporting app has to be downloaded as a pdk app. Combined with the watch automatically defaulting to Chinese this took longer than it should have ro achieve.
