You’re Lucky You Can See the Ninja Watch

Everybody knows Ninjas exist, but you can’t really see them unless they want you to. Stealth is the way of the ninja, even when they appear in a form so benign as a watch. Ninja Time Watch by Andy Kurovets shows the time stealthily, mimicking the face of a ninja with only the eyes visible. Eyes of the ninja function as dials of the clock, separately showing the hours and the minutes.
