I've seen this occasionally, and as far as I can tell the lcd changes its optical properties very slightly depending on the power state of the watch. It's too fast to be a display update and the blink rate goes up dramatically when I pick the it up and the watch starts querying the accelerometer more often looking for a "twist" gesture.
