With the ExactSet projection clock from Oregon Scientific, you can be as on time as the most accurate clock in the U.S. That's because the ExactSet clock uses radio frequency to pick up signals from the U.S. Atomic Clock in Boulder, Colorado. The result is an extremely accurate timepiece that updates itself six times a day, never needs resetting, and adjusts automatically for daylight savings. The clock has plenty of convenient features, too, such as the crescendo alarm, the eight-minute snooze, and the dual display that shows current time and alarm time at once. The clock also features a swiveling arm with a 90-degree rotation and a 12-foot range that projects the time in red when you push a button. Backlit with a pleasant blue glow, the screen also indicates the date and day (in English, French, or Spanish), as well as time zone, alarm status, and radio-frequency strength. Powered by two AA batteries or the included AC adapter, the clock only works in the continental U.S.
