Wake on touch would be more accurately named wake on tap - leaving the touchscreen on would draw too much power, so instead it detects the vibration from you tapping the watch.
Is it possible that something caused the watch to vibrate? If I enable wake on touch, I can unlock my watch by shaking or banging on the table it's sitting on.
