Pujie Black is one of the best custom watch faces for Wear OS devices, and it has gone through update after update over the past few years. It's endlessly customizable — even more so with the latest update. Version 4.0 of the watch face is now available on the Play Store, with a few new major additions.
The most important new feature is the ability to add image layers to watchfaces, so you can set custom backgrounds or watch hands. You can also use vector drawings created with the Pujie Black phone app.
