This is the watch that derives its unerring accuracy from an atomic master clock that neither gains nor loses a second in 80 million years.
The watch automatically calibrates itself up to six times a day via a radio signal from the U.S. Atomic Clock in Fort Collins, CO, ensuring that its luminescent hands and LED lit digital panel display the time precisely. The watch automatically adjusts itself for daylight saving, and when traveling between time zones, the touch of a button displays the local time.
It includes a calendar, an integrated stopwatch, and can be set to sound three daily alarms or to chime on the hour. A rechargeable battery stores solar energy collected by a photovoltaic cell in the watch's face, providing up to five months of use from a full charge. Water resistant down to 300'. With a stainless steel bezel and adjustable 3/4"-wide silver metal band that fits wrists 6" to 8".
Watch case 2-1/8" L x 1-3/4" W x 1/2" D. (3-1/2 oz.)
