10 Inch Atomic Wall Clock

This clock can always have the exact time and has settings for the four major U.S. time zones. It is a large clock housed in a plastic frame and requires only one AA battery to operate. It's accuracy is based on a radio receiver in the clock that synchronizes the clock with an atomic clock in Boulder, Colorado.

I like this clock's ability to adjust itself for daylight saving time so the user doesn't have to worry about "spring forward, fall back".
