BALDR Atomic Alarm Clock - Large Color Display Digital Desk Clock - With Indoor Thermometer for Temperature & Humidity - Date & Real-Time Moon Phases - Perfect Office Clock or Nightstand Clock (Black)

Our atomic clock automatically adjusts the time and calendar date with the WWVB radio broadcast by the NIST in Fort Collins, Colorado. The clock also self-updates for daylight saving time (DST). Please note that the atomic feature only functions in North America and works typically at midnight or in the very early hours of the morning. The clock features a white backlight with adjustable screen brightness, making it easy to read the time, date, weekday, indoor temperature, humidity, and real-time moon phases, day or night. It also comes with a snooze button on top to allow you to catch a little extra shuteye before alerting you again, and a sound that turns off but automatically comes on again after five minutes. The clock is powered by the supplied AC adapter and includes a built-in CR2032 cell battery to store the time and alarm settings if the power is interrupted. A low battery sign will appear on the clock when it is time to replace the cell battery. You can activate the dimmer feature by pressing the "Snooze/Light" button on top of the clock.
