There are literally hundreds of watch faces for the Gear2. You can download a bunch from the Samsung Gear App store.. Some are free, and some cost a buck or two.
I get most of my watch faces from
GearFaces | Let's Face it, you want it! They provide hundreds of downloadable faces for the Gear2 and the GearS. (When you go to the site, click on the WS/MW link on the top right of the screen to see all the available faces). All the faces except the ones specifically for the GearS will work with the Gear2 and Gear Neo.
Everything is free there, but if you like the site, you should support them with a voluntary donation.
You'll need to download an app to your phone called Watch Styler. It allows you to import the faces and load them on your watch. You can also use Watch Styler to create your own faces from scratch, (both digital and analog). My forum avatar on the left is a still shot of a functional watch face that I created with Watch Styler.
