A bumper case to add some protection to your watch, and more custumization options! Designed to work with the asus zenwatch charger, so you don't have to remove it to charge your watch. If you wish to remove it, push it out from under the watch instead of pulling it off from the top.
You have the option to add word of a maximum of 6 letters to add an extra level of personalization.
There's a variant for the zenwatch 2 available here http://shpws.me/M66l
