Whether mounted indoors or outdoors, this 18-inch round analog wall clock reports the time, temperature, and humidity at a glance. This clocks claim to fame is its precision time-keeping and the fact that it never needs to be set. 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. As an additional perk, the clock features a hygrometer in the lower left area of the face that measures the percentage of relative humidity in the air. The lower right has an analog thermometer that reports the temperature in both Celsius and Fahrenheit degrees. This radio-controlled clock is covered by a 1-year warranty and runs on one AA battery (not included). --Cristina Vaamonde
