Hot Lee Valley Atomic Radio-Controlled Clock

Designed to receive the radio signals emitted from the Atomic Clock in Boulder, Colorado, this clock automatically calibrates itself six times daily to ensure accuracy; it even updates for Daylight Saving Time changes.

With an 18″ diameter bezel, the 13 1/2″ dial has oversize numerals for legibility from a distance, and includes a Celsius/Fahrenheit thermometer and a hygrometer to measure relative humidity.

Designed primarily for indoor use, it is usable outdoors in sheltered locations and temperate conditions. Runs on one AA battery (not included).

Please note: the radio signals broadcast are detectable in most parts of Canada (except the Yukon and Northwest Territories, Nunavut, and the Atlantic provinces) and throughout the United States (except Alaska and Hawaii). For areas where there is no signal detection, this clock will operate as a normal clock and will require manual time correction as necessary.
