Here's one of the improvements Google might want to look into for the Pixel Watch 2: better glue. Android Police spotted a few reports of the back panels of some Pixel Watches just falling off. A few posts on the PixelWatch subreddit have photos of this phenomenon; several commenters say it happened to them, too.
This certainly seems like something Google should cover under warranty, and with the device being less than a year old, everyone should be under warranty. You also have a strong argument if you contact Google support about a device that has fallen apart. The scary thing is this will also compromise the device's water resistance, and we doubt Google is covering every instance of water damage. Most reports indicate Google is taking care of the problem, but a few users were initially threatened with a $300 repair fee, which was later waived.
Thanks to my excessive sweating (I believe) the glue on the back of my pixel watch dissolved and the back has popped off. pic.twitter.com/ltUQauXC4I

When iFixit tore down the Pixel Watch, it noted the back adhesive was a novel "liquid gasket" the site had never seen before. The report said, "The rear glass appears to be held in place by a kind of liquid gasket that seals tightly, but comes open clean. It also peels off the glass with virtually no residue." It sounds like Google's fancy glue peels off a little too easily. Poorly adhered back panels were also a recent problem with Fossil watches, and in the "Gen 6" versions, Fossil acknowledged the problem and said it was fixed.
We all know manufacturers like to build completely fastener-free smartphones, but it's not unusual to see visible screws on the back of a traditional watch. Some watches turn the entire back panel into a giant screw, with a threaded edge running along the back cover, and the whole thing screws into the watch body. Maybe a real fastener would help the Pixel Watch.
