The pixel watch is pretty much the worst smart watch I've tried. I've used the apple watch s3/4/7 and the galaxy watch 4 classic and the 5 regular and the pixel watch is pretty useless in comparison to either, with the apple watch leagues above either. Basically every nicety I expect to be there isn't. Alarms don't sync with your phone, notifications go off on your phone then your watch as opposed to one or the other, do not disturb doesn't sync with your phone, theater mode only affects your watch, the battery life is atrocious.
I get that it's Google's first go but I can't in good conscience recommend it to someone else. Maybe with the 2 they've resolved these issues but what I stated to me I feel like are pretty basic features to include. Using my apple watch for the first time was great, it felt like an extension of my phone. Turning one setting on my watch affected my phone so I didn't need to touch it. Setting alarms on my phone turned them on my watch so I didn't need to do it again on my watch. Every time I use my pixel watch I have to remind myself to do it on my phone too so they don't conflict. The health tracking is neat I guess but you need a subscription for Fitbit once your free one expires... pretty terrible. Look elsewhere imo.
