This is the atomic watch that will never be off by a second. It receives a radio signal up to six times a day from atomic clocks located in the U.S., Germany, England, Japan (two), and China—a timekeeping standard that neither gains nor loses a second in 80 million years. It has an automatic calendar, adjusts for daylight saving, and has a luminous coating on the hands and analog markings. The watch can also display time digitally in 12- or 24-hour format and has both an integrated timer and stopwatch. The watch recharges via a solar cell that is powered by both indoor and outdoor light. Water resistant up to 656'. Imported. Black or Black/Silver. Fits wrists from 53/4"-81/2". Watch case 2" L x 13/4" W x 1/2" D. (2 oz.)
