Sharp 12-Inch Atomic Wall Clock, Battery Operated, Glow in Dark

GLOW IN THE DARK ATOMIC CLOCK: See the time, Day or Night!, with the Sharp Atomic Clock with Glow in the Dark numbers and hands. For best results with the Glow in the Dark function: when you first receive the clock, place the clock in sunlight or bright light for 24 – 48 hours. After this time period, the clock will glow in the dark. The clock benefits from exposure to light during the day for optimum glow at night.
ATOMIC ACCURACY: The Atomic clock has a built-in receiver that automatically synchronizes itself with the WWVB radio broadcast by the US Government’s National Institute (NIST) in Fort Collins, Colorado. The Atomic Clock will always be accurate to within one second as it receives daily WWVB updates.
AUTOMATICALLY SETS: Clock resets regularly by radio-control to match the US Atomic Clock in Colorado and adjusts automatically for daylight savings time
