The software update will arrive on all half dozen of the existing Android Wear devices, where users will be able to check out the new watch faces that can be found in Google Play. Google has collaborated with several developers to offer a few of these custom watch faces at launch, including those from Porsche and Rebecca Minkoff that you can see above, not to mention others that will feature game as well as movie themes. Heck, Google will also offer an API so that more folks can design additional custom watch faces. This ought to be interesting, since it would mean you can have the same base model, but feel as though you are wearing a different watch from time to time due to the soon-to-be numerous watch faces made available to the masses.
Other features that accompany the software upgrade include the provision for animated watch faces. Do take note that animation would cause a battery drain, but hopefully developers will be able to code it efficiently to keep that to a minimum.
