Jumbo Digital Atomic Clock

These digital clocks set themselves automatically by tapping into the time signal broadcast from a cesium fountain atomic clock located in Boulder, Colorado. Accurate to 1 second every 60 million years, the atomic clock signal is broadcast all over North America by the National Institute of Standards and Technology. With a built-in weather station, large-sized numbers and atomic clock-based precision, this elegant LCD alarm clock can be mounted to a wall or set on a desk. The easy-to-read display indicates not only the time, but also the day of the week, the temperature and the humidity. Requires 2 AA batteries, not included.
