Yes there is. Sharp has their memory-in-pixel LCDs which are reflective and have less power consumption than traditional LCDs for some tasks. They've been used in stuff like the Pebble watches and the current Garmin Fenix line. I think a few of their denshi note devices have also used them. I don't think they make them in sizes big enough for stuff like monitors though.

The contrast on these screens is so low, I'd love to get little e-ink screens on the sports watches. Right now, especially in mixed-sunlight dappled forest kind of backgrounds, you really need to take a hard look at the screen to read anything, which isn't safe if you are trail running or mountain biking or something similar.

Please watch makers, put a little eink-style screen on a watch! Even if it looks like 1st Generation Kindle screens, and is only black/white, it will still be an upgrade!
