Description

Be ready for the day with the La Crosse Technology's Digital Atomic Clock with temperature. This timepiece comes with convenient features to provide information you need to know. The self-setting clock wirelessly gives you accurate time and date, so you’ll sure to be on time. It has a WWVB radio signal antenna for the time’s best accuracy and automatically resets for daylight savings' time. It also functions as an alarm clock and offers a crescendo alarm (gradually increasing) with an extra 10 minute snooze. The clock is battery operated, so it will keep the correct time after black outs or power surges. It will also indicate when it’s time to change its batteries (requires 2 AAA, sold separately.) This time-keeper gives you the ability to be prepared for almost anything. It offers seven different factory-set time zones (Atlantic to Hawaiian), so you need to do is select your time zone, place the clock facing the WWVB signal direction (NIST tower located in Fort Collins, CO USA) and time will automatically set your time and date, accurately. Monitors the indoor room temperature and can display in either Fahrenheit or Celsius. All you have to do is take a glance, and you will be set for the day.

    • THE VERY BEST!
Color: Cool Gray Size: 4.49 x 3.86 x 0.71 Style: Contemporary
The Digital Atomic Clock with accurate temperature telling is a pleasure to use. The temperature fluctuates, during the day AND night, so, it is great to consult the clock!

    • Great customer service!
Color: Black Size: 6.25 x 5.25 x 2.50 Style: Contemporary
The first atomic clock we received would not sync up to WWV no matter what I tried! I wrote to the company explaining my problem and the things I had tried. They immediately responded with apologies and sent me a replacement unit. The replacement works great! Customer service was outstanding! I would highly recommend this product as with everything, stuff happens! But when things go south, it is nice to know the company stands behind their product! The replacement syncs fine and is accurately displaying time and inside temperature! ... show more

    • Budget, ok-ish small atomic clock
Color: Black Size: 6.25 x 5.25 x 2.50 Style: Contemporary
It's a decent digital "atomic clock" for $20. Size-wise the display is a little small for the size of the unit, and the bezel is unnecessarily large. Day, date, temp are all nice features here. For me, it can't sync on its own with atomic time: but it's located inside a bathroom inside a large apartment complex on the east coast, so I can't really fault it. So I used the WWVB android app to sync to atomic time without problems. One issue though as it can't adjust daily then is that it will drift as its quartz clock does. For me, it's +15 seconds in a month. Which, while not atrocious, is probably a little worse than I'd expect an out of the box Casio to do in real life. If you want something that looks better, I think WallerGe offerings have better looks and deliver far larger displays and digits while only being slightly larger physically. ... show more

    • Very large, easy to see display, atomic clock auto set, but location dependent...
Color: Black Size: 6.25 x 5.25 x 2.50 Style: Contemporary
Bought one of these a few years to mount on wall behind 24" HDTV sitting on counter in my kitchen, this clock fit perfectly below the upper cabinet and above the TV, large numbers were easy to read from about 8 feet away, but it would never connect to Atomic Clock server in Colorado, and worse, it would gain up to 2 minutes or more over a few months, having to reset the clock periodically became frustrating, why I bought another, (this one), with hope it would connect with time server. I set up the new one, tried to connect to time server manually, would not connect, so put it up in same location over the TV hoping it would connect overnight, nope! The irony? I reset my old clock, put it on a nightstand in guest bedroom, to my surprise, the old clock connected to time server overnight! (shows the icon indicating it connected). I did some research and it seems electronic devices can interfere with time server signal reception, so most likely due to being too close to the HDTV in my kitchen setup. The good news, I set the new clock using Exact Time website, down to the second, this morning I checked the new clock against Exact Time website, it is still spot on. Hopefully the new one will keep proper time without having to connect to the time server. I like the clock, so will just deal with reseting the clock as necessary, other features, at least for my situation, outweigh any slight loss of time. Bottom line, if you are buying this for the atomic server automatic setting capability, keep its location in mind, it may not work if close to electronics or anything else that may interfere with signal reception. ... show more

    • Doesn't work as an atomic clock.
Color: Cool Gray Size: 4.49 x 3.86 x 0.71 Style: Contemporary
This is supposed to be an atomic clock. It picked up the signal once and then lost it, and it has never come back. In giving it the greatest chance to work, I ran past the return period. Very disappointing.

    • Hard to see unless room is well lit
Color: Black Size: 6.25 x 5.25 x 2.50 Style: Contemporary
The clock is almost automatic, put the batteries in and it sets the time. Wanted to have it in a family room on the Television stand because we had gotten used to the cable box displaying the time and we cut the cord. It was impossible to see the time when the clock was on a lower shelf. I moved it to my workshop where the lighting is better and it is easy to see. ... show more

    • Good clock for the money ... but why does it come in a Walmart box?
Color: Black Size: 6.25 x 5.25 x 2.50 Style: Contemporary
Right out of the box - which, as another recent reviewer noted, is a Mainstays box, complete with "Distributed by Walmart" on the back!? - the clock was easy to set up. Just pop a couple AAA batteries in it, follow the directions on the back to manually set the day, date and time zone, and then the clock did the rest. It was set to the second and keeping accurate time within just a few minutes. The display size is perfect for my bathroom, and it is easily visible from every angle. It is smaller and lighter than my previous clock, but seems to be made very well. ... show more
