NeXtime 35cm Wall Clock - Glow in the Dark BlueThe NeXtime "Globe Dome" is a wall clock with a dome shaped glass and made with the latest glow in the dark technology. To charge the glow in the dark hands and image, hang the clock in daylight for at least one day. The hands and earth will then light up in the dark for approximately 4 hours. A great gift for children and teenagers alike, the clock is silent and runs on 1 AA battery (not included).
