The Only Atomic Pocket Watch.

Exclusively from Hammacher Schlemmer, this is the only pocket watch that maintains its unerring accuracy by radio signal from an atomic clock. Providing accurate time across the entire lower 48 United States, it receives a time signal from the radio clock transmitter in Fort Collins, Colorado once per day, ensuring that it will never gain or lose a second for 30 million years. The case is made from surgical-grade stainless steel; the watch face uses analog hours and minute hands with an LCD that shows date and seconds (a press of a button alternates between date and seconds). The 14" stainless steel chain terminates in a lobster-clasp. 2" Diam. x 1/2" D. (4 oz.)
