The watch face selection for the charge 3 is pretty slim but I think one key feature was overlooked on all of them. If a fitnesses band is going to be interlaced with smart watch capabilities that rely on a bluetooth connected device then there should be an icon to let you know if you are still connected to the device. If im not near my phone, I have no way to know if my band is still connected and if im missing important notifications until I go look at my phone.
I made up my ideal watch face with all the things I think are important and should be seen at a glance. I included the bluetooth icon right in the top corner, since its a pretty important part of the band functionality. If the phone is no longer connected to bluetooth then the icon should disappear so there is no mistake if you are connected or not.
