Although I would definitely be petrified of the jellyfish in real life, I love the animations on the watch face. Unfortunately, I have a great dislike for digital faces, and so use the Utility face as I can have the date, weather, battery and small readout of digital time (it is useful in specific situations, but I don't want to rely on it for general timekeeping). It's more utilitarian (hence, I suppose, its name!) but much more useful.
How hard would it've been, Apple, to have a nice simple white analogue overlay over the jellyfish and butterflies? 😛 Isn't this meant to be the most personal device yet?!
I am joking (slightly - I seriously would love an analogue + jellyfish face), but if you prefer analogue faces there isn't a great selection. Utility is pretty nice, as is Simple, but Colour just doesn't look very nice (in my opinion), Mickey Mouse is impossible to tell the time on, and Chronograph's constant stopwatch hand annoys me. (Though it's probably just me.)
