I can use any WS/MW watch faces from http://gearfaces.com/?cat=51
with WatchStyler on my Gear2neo with Note3 and Note4
1. Install WatchStyler from Galaxy Gear App store
2. Download desired watchfaces from gearfaces to your phone
3. Open WatchStyler app (from your phone app drawer, not from gear setting app)
4. Press Load theme button, and choose "My files", app will scan your phone for downloaded watchfaces and will shoow it to you.
5. Repeat step 4 if u want to add more than 1 watchface
6. Go to gear manager, watchfaces selection, choose WatchStyler, press the gears (settings) button and choose desired watchface, usualy u will need to go back and set any basic watchface and after this switch to WatchStyler again to apply new watchface.
Hope it helps.
