I did manage to scratch them quite a bit I have to say, so not impossible

I was expecting them to do bit better. Overall really good watch and probably my only small complaints are the durability, the fact I tend to press the button to trigger Siri when I use my hand for push / support (happened to me with AW4 before but more frequently now due to size I guess) and then lack of some or more functional apps (WhatsApp, uber, trainline in the UK).
