Smart Watch Faces

I got a smart watch for Christmas and I’ve been slowly learning how to program it to look the way I want and display various bits of information. For example on this face, the spark plug counts the hours while the coilover counts the minutes. The rotating wheel is actually the second hand, doing a full rotation every 60 seconds. The needle and gauge displayed on the brake disk show the battery level of the watch.

Note: I am aware that the brake disk is not rotating with the wheel, but in my opinion that would have not worked as well or looked as nice in the end. Also I have posted an HD image in the comments since the gif is low quality

The reason I am posting this on Carthrottle (besides just showing it off) is because I was curious if anybody here had some interesting ideas for new faces or critiques about the one I’ve shown here. I am open to car related or random suggestions, just looking for something new.

I doubt this will be necessary, but if anybody else who has a smart watch would like me to make a custom face for them, I can do that.
