One of the main reasons to use an Android Wear Watch vs a traditional watch is the ability to change the look of your watchface whenever you like. You could change your watchface several times a day to match what you are doing (ie traditional watchface for work, fun watchface for home).
Mysterious Forest is an interactive watchface that seeks to bring a new aesthetic to your device. From the watch face when you touch your device a deer, rabbit, or bunny will appear with a peeking animation. There is an ambient mode which allows you to always see the time without killing your batter. The watchface supports both round and square watch faces, and there is a customizable time format.
