The "Luminous" wall clock has a white dial with the latest glow-in-the-dark technology.This clock is perfect for any room but especially the bedroom, due to it's silent movement (so no ticking sound) and the white dial that light up at night so you can even read the time at night!  The clock needs to be hung in the daylight to be able to charge and will then light up in the dark for approximately 4 hours. This clock has a black case and runs on 1 AA battery (not included).
