Essential Info

This clock simply couldn't be easier to use. All you have to do is insert an AA battery (sold separately) and press your corresponding time zone button, that's it! The clock receives radio communication from Fort Collins, Colorado, where the exact time signal is continuously broadcast throughout the United States. Time is precisely measured by the Atomic Clock of the US National Institute of Standards and Technology, Time and Frequency Division in Boulder, Colorado, where a team of atomic physicists continually measures time to an accuracy of ten billionths of a second per day. The clock will recognize PT-Pacific Time, MT-Mountain Time, CT-Central Time and ET-Eastern Time, and automatically adjust for daylight savings. It is suitable for indoor use as well as outdoor use in dry environments in a temperature range of 41°F to 131°F.

Please Note: For time zones outside of PT, MT, CT or ET you must manually set the time using the Manual Time set button on the back of the movement.

Hands On Research
At first the clock went to 4 o'clock and stopped. Upon reading the manual, I learned that every even hour is when the clock looks for a signal to set the clock to. Within a couple hours the clock read perfect time and everything was working great.

    This is the best clock we have ever had. It is so easy to start, looks good, and is a great value.

    Great product at a great price. We purchased four and all are performing flawlessly. One is at our cabin on the Selway River in Idaho and miraculously receives the signal from WWV even though we are on the river at the bottom of the valley.

    Great product at a great price.
    RICHARD -- dunbarton, NH   3/5/2012
    Accurate time and simple setup. All I had to do was install the battery and in about 5 minutes the clock had syncronized with the atomic clock and was keeping perfect time. I woud recommend this clock to anyone wanting an accurate easy to read clock.

    WENDY -- knoxville, TN   12/31/2011
    Ihave always bought this clock at Sam's Club for $11, so the price seemed a little high to me. Then it was backordered, so it too about a month to come in. The clock itself is fine.
    BOBBY -- bridgeport, TX   8/27/2011
    Great, This is the only clock to have. The automatic reset of the time every day and at day lite savings the only way to go.
    MARK -- rochester, NY   8/11/2011

    good product
    MARILYN L -- belmont, VT   5/24/2011
    I gave this clock as a gift and the recipient is delighted. At first she was concerned that her preferred placement would not work - between the refrigerator and the microwave - but it was fine. She is happy to be able to see the large numbers from her chair in the living room.
    DARON -- conway, SC   5/7/2011
    Nice clock, price very competetive, I use it outside in direct sunlight, I get 2 years of use, bought two of them they are cheap enough to dispose of when they quit working.
    STEVE -- rock hill, SC   5/5/2011
    The owners manual stated the clock could be set to another time zone manually (other than the four in the continental US) However, the clock always resets to one of four time zones. Therefore it doesn't work for my use.
