Google is also working on a new set of Pixel earbuds, the Pixel Buds 2, and will reportedly release the new devices all at once along with the next-gen Pixel 3 and Pixel 3 XL smartphones. The new Buds would hopefully keep the excellent battery life, but improve the things we didn't like about the old ones, namely the poor Google Assistant integration, wonky touch controls, and lack of ambient noise blocking.
A Pixel Watch makes a lot of sense. Wear OS (formerly Android Wear) devices are getting better, but they still haven't captured the public's imagination the way the Apple Watch has. If Google can create a solid reference design (or designs), they might inspire other manufacturers to do better.
There's no word on what a Pixel watch would look like, but if Google builds more than one, it would make sense to have a model dedicated to style and another to sports tracking, much like LG did with its Watch Sport and Watch Style. In any case, if Qualcomm's promises about efficiency hold true, you can expect better than the two day battery life offered by most current Watch OS models. That alone should make them much more interesting to buyers.
