Feel stupid having to ask on a forum as I've been around Android for a while. The app doesn't have an open option to open.. And I can't find the settings to customize in the Android wear app.. Any help.?
Some of those can be changed in the Android Wear app...
Go into the Android Wear app, tap MORE to the right of watch faces, then tap the three little dots near each watch face and select settings.
Some of the watch faces, like "Digital" have to be customized on the watch itself. To do this long press on the watch face (as if you wanted to change your watch face), then select the little gear icon under the watch face. This doesn't appear on all watch faces, so some discovery is required.
