Essential Info

How accurate is your clock? Never worry about setting your clock again with this maintenance-free wall clock that automatically sets itself against the most accurate clock in the world. The 18-inch Atomic Clock with Thermometer has an indoor or outdoor temperature thermometer depending upon where setup. This weather-resistant timepiece runs on one AA battery (sold separately) and is suitable for outdoor use but should be sheltered from direct sunlight.


What's Included

  • 1x - Clock
  • 1x - Instructions
  • More Info

    Just insert the battery, select a time zone with a press of a button, and the clock's hands will move into place by themselves when it receives nightly radio signals regulated by the U.S. Atomic Clock in Fort Collins, Colorado. The clock even self-adjusts for Daylight Saving Time within five days, although this feature can be disabled if you live in an area that doesn't change clock settings twice a year.

    The Atomic Clock with Thermometer has two analog sensors that measure the surrounding temperature and humidity. You'll be able to see at a glance the humidity percentage as well as the temperature in both Fahrenheit and Celsius degrees.

    Love this clock! It's easy to see with the large numbers. The company was great to work with! I made a mistake and ordered 2 with in minutes. I'm new with the computer. Contacted the company and they issued my return without charge tro me. I will check with them before ordering anything else they carry. Excellent company to work with and products!!!!!!

    Most useful clock I've ever had.
    REAL ESTATE -- novato, CA   6/4/2011
    So far so good.
    MARIANO -- chesterfield, VA   2/6/2011
    States it's an outdoor clock yet it is not weather resistant and can only be placed in a dry location.... that makes it no different than an indoor clock.
    Jocelyn -- montreal, Canada   11/10/2010
    Very nice, using it in my HomeCinema, always accurate, hour changed only one day after Daylight saving time. Never changer batteries since 3½ years working. Very good product
    BENSON -- sharon, MA   8/12/2010
    Using the product outdoors on my pool house. Turned it on, it worked, and no problems
    CHRIS -- berkeley, CA   6/26/2010
    I really like how big the clock is, although it is not heavy, and I find the temperature and humidity readings useful. Of course, always having the right time is great.
    JOSEPH D -- lecanto, FL   6/4/2010
    I have it outdoors on a covered patio and it works great.
    CHARLES DECOU -- arlington, VA   1/5/2010
    Excellent clock which works very well. I recommend this product to anyone!
    MAX -- long valley, NJ   8/5/2007
    The size is perfect. At 78 years old, I don't like to get on a ladder for the spring and fall time change.
    L DALE -- las vegas, NV   7/28/2007
    This is my second Atomic clock from you like this. Great Product! Works great, looks great, easy to read.
