La Crosse Technology 9 in. L X 1-1/2 in. W Indoor Contemporary Digital Atomic Wall Clock Plastic

It is a small wall clock that makes a big impression. The large, high-contrast display is easily seen from across a room. Hang this clock on a wall or stand it on a desktop for convenient time, date, day and indoor temperature information from 14.1 to 139.8 degree Fahrenheit (-9.9 to 59.9 degrees Celsius). Atomic clocks work so accurately because they synchronize with the master clock at the U.S. Naval observatory, the official source of time for the U.S. department of defense. This contemporary wall clock automatically updates to daylight-saving time and features U.S. time zone selection for eastern, central, mountain and pacific time.
