The Giant Display Atomic Wall Clock

This is the oversized wall clock that maintains its unerring accuracy from the radio clock transmitter in Fort Collins, Colorado. Its digital display uses 4 1/4"-high numbers, allowing you to easily read the time from up to 30' away. In 2"-high numbers below the time, the display provides the date, day, indoor and outdoor temperature. It includes a wireless outdoor thermometer that communicates with the clock from up to 330' away, providing a range of -4 F to 122 F. Includes automatic Daylight Saving Time adjustment, alarm, and 12/24 hour time format. Providing accurate time across the entire lower 48 United States, the clock’s radio receiver synchronizes with NIST-F1, the United States’ atomic clock which will never gain or lose a second in 60 million years. Mounts to a wall or stands upright with swing-out arm. Requires three C and two AAA batteries. 10 1/2" H x 16" W x 1 3/4" D. (3 1/2 lbs.)
