Google Pixel Watch 3 renders have apparently leaked, and it looks like not much is changing except for a slightly chunkier design. As revealed by 91mobiles and OnLeaks, who uncovered a rumored “Ultra” Galaxy Watch from Samsung last month, the Pixel Watch 3 may arrive with a slightly thicker case to accommodate a new 307mAh battery, up slightly from 304mAh in the Pixel Watch 2.

The measurements listed with the leak (along with a 3D spinning video) are 40.79 x 40.73 x 14mm versus the Pixel Watch 2 at 41 x 41 x 12.3mm. Whatever size they are, any new Google wearables coming this year will likely ship with Wear OS 5, which Google said will help enhance battery life.
