The TTMM watch faces are the most unique I have found. I especially like the TTMMINUS face. ((If you buy the group of watch faces I put in the first link it includes the watch face you see in the second link)). They also have a second group of faces here.
TTMM #1 and TTMM #2 are what you're looking for. I have the original zenwatch, most of the faces look pretty good on it. One or two of them however show a black screen when dimmed which is kind of annoying. Hopefully they'll fix that.
