1. It's too fancy. I work a lot with my hands, and am afraid of beating the watch up with daily use. So far it's been fairly scratch and damage proof, but it's only a matter of time before it makes contact with a surface that will scratch it.
2. The gesture doesn't work very well. I have to over exaggerate my viewing gesture in order to see the watch's updates/alerts. I also can't wear it on the inside of my wrist for the same reasons.
3. It's rude. If I get an alert on my phone, while in the pocket, during the middle of conversation, I can check when the conversation is over. Not so with the watch. It's thumping and alerting me with every alert, which is a distraction. Furthermore, there's nothing worse than talking with someone and seeing them check their watch. Are they too bored? Are they in a hurry? No, they're checking their phone/watch.
Overall, I didn't feel like it added any value, and felt like it made interactions with people even more awkward.
