Can't say I've seen it for Apple or Android watches, but for pebble there's a nice app to let you watch the status of your 3d printer if you use octoprint. It's ended up great as a gauge for how long a print has left, even gives a convenient way to stop a print without killed the power to the printer. Sure I can use a phone for the same thing but when I've got it on my wrist with a single button press? much more convenient.
