Look out the window or across the yard and always know the exact time, temperature and humidity. This clock/thermometer/hygrometer has an 18 face for easy viewing. And because it's linked via radio signal to the official U.S. Atomic Clock, it's always precise and automatically adjusts for daylight-saving time. Rubber gaskets lock out moisture. This clock also has a glass crystal and metal frame. Runs on one AA battery (not included).Available: Silver, Realtree MAX-4 .
