Universal® Deluxe Indoor/Outdoor Atomic Clock, 13 1/2", Black Frame, White Face

A fully sealed, weather-resistant case and large, easy-to-read numerals on its face make this clock ideal for high-humidity, outdoor environments. As it maintains radio contact and automatically synchronizes with the National Bureau of Standards' atomic clock in Boulder, Colorado, it can be relied upon for up-to-the-minute accuracy and precision. For added convenience, it also automatically adjusts during Daylight Savings Time changes.
