What's a good Android app for a watch face that looks kinda cool without draining the battery before lunch?

Look, I'm not gonna lie, finding a watch face that looks halfway decent and doesn't suck the life out of your battery is a pain. This Plasma Flow Lite Watch Face, it's…okay. The plasma effect is kinda neat, gives it a bit of flair without being too flashy for the job site. I wouldn't say it's 'built like a brick house' or anything, but it's held up so far. Rain doesn't seem to bother it, which is a plus when you're working outside in Denver. Battery life is still a concern, though. I'm still charging every night, but it's not as bad as some of those other fancy ones I tried. It gets the job done if you want something that looks a little different without sacrificing too much battery. Don't expect miracles, but it's not the worst I've seen.
