La Crosse Technology WT-3144P Atomic Wall Clock

This clock sets itself to the U.S. atomic clock in Boulder, Colorado, thus maintaining absolute time accuracy. It also adjusts automatically for Daylight Saving Time.

Framed in a matte, pearl-colored plastic, this wall clock measures 14 inches in diameter and looks most at home hanging in an office or business setting. However, this clock’s claim to fame is precision time-keeping and the fact that it never needs to be set. The clock has a built-in antenna system that receives signals from the WWVB radio transmitter in Fort Collins, Colorado, which is in turn is regulated by the atomic clock. Once you install the battery and choose one of four U.S. time zones, the clock automatically sets to the accurate time in hours, minutes, and seconds, and continues to adjust itself six times daily. This low-maintenance clock even automatically adjusts for daylight savings time, so you never need to remember to spring ahead or fall back. This radio-controlled clock is covered by a 1-year warranty and runs on one AA battery (not included). --Cristina Vaamonde
