WallarGe Atomic Clock with Outdoor and Indoor Temperature - 12.5 Inch Self-Setting Digital Clock Large Display, Battery Operated Wall Clocks or Desk Clocks for Bedroom, Livingroom, Office

The clock was fairly easy to set up, and functions perfectly. I now know the exact time, and the correct indoor and outdoor temperature. The clock is very easy to read. I highly recommend it.

The atomic clock is excellent if you want precise, automatic timekeeping without ever needing to reset it. It automatically syncs to the correct time (including daylight saving adjustments), which is perfect for busy households or offices. The display is clear and easy to read — whether on a wall or a desk — and many models offer extra features like date, temperature, and alarm settings. I also appreciate how low‑maintenance it is: once it’s set up, it just keeps accurate time on its own. If you want a hassle-free, reliable clock that you don’t have to think about, an atomic clock is a great investment.

Oct 2024 Update: The new clock the company sent me appears to be working a lot better than the one I originally got so I have increased the stars to 5. It is not completely glitch free but we haven't had anywhere near as many problems with it as we did with the first one AND the glitches are no worse than what we had with our 2 previous atomic clocks made by other companies. I now believe the first one was probably just a defective clock and this one is more representative of the clocks quality. As stated below this company reached out to me after reading my review and replaced the clock that was no longer eligible for return due to the time that had passed. That says to me they stand behind their product making this clock worth purchasing. March 2024 Update: The company contacted me after reading my review in an effort to try & resolve the problem. After their suggested fixes didn't work, they offered to send me a new clock, free of charge, in the hope that the first one was just defective. It is so rare anymore to find a company that actually tries to make sure their customer is happy. I will come back & update this review again once we have the new clock and have given it a few months to make sure it works properly. Love the look of this clock, love how big the numbers are and how easy it is to read everything even at a distance. With that said, all that is great as long as the clock keeps the correct information on its display. This is not our first Atomic clock, it is our 3rd, but it is the first one that has had this issue. We hung it in the exact same place the others were hung. However this one, on several occasions, has jumped ahead to a different date and time when it did its updating. Unfortunately, the first time it happened we thought it was a one time thing and that it would be fine but it has done it several times now, of course well after the return date has expired. While it is a relatively easy fix, you just have to move it to a window and leave it there until it corrects itself, you shouldn't have to do that at all, at least not multiple times. Since we can't return it we will live with it for now but I will not buy this brand again and I would never give it to someone as a gift. Our previous clock was a Panasonic and we will probably go back to one of them when we decide we have had enough of this one and its issue.

Quality of this clock is very good overall. It shows the proper indoor and outdoor temperature. Size is just right for the space we installed it. Can see the display very clearly in the light but cannot see it at all in the dark or dim lighting. One thing that is quite weird, is that once or twice a year the time will move ahead on its own about 2 hours, even though I have it set for automatic time change. Then in a week or so it will go back to the correct time on its own. Not sure what that's all about.

Awesome clock! Set itself to the right time & zone within 10 minutes! I have never had such an easy atomic clock! It had directions! The back/buttons are easy to read. Lots of white space & bright. It even came with screws for wall mount & a pattern to drill the holes! It’s a little smaller than I thought it would be, but I must have misread the measurements.

Easy set up. Love the size. Easy to read

The functionality of this clock is excellent- once initialized, correct time is displayed unaffected by power failures, and indoor & outdoor temperatures are well displayed. For those with the need to know daily metrics, this is a high quality instrument at low cost that WORKS! Recommended!

This clock can be set to display 24-hour time, making it about half the price of a La Crosse that does the same thing. And, since the clock was my greatest need, I went with this model, since I needed two. I am really impressed at how quickly this clock will connect with WWV in Fort Collins. Typically, my La Crosse clocks would sync up overnight. But these clocks, as soon as they were up on the wall, had synced up with the WWV signal and were displaying all of the correct time data (that's impressive because I am almost 1400NM from Fort Collins and this was about 1800 EDT, which is rather early for atmospheric propagation). Five stars for the clock function. If you don't need a clock that tells you the outside temperature, then skip this part. I knew the temps would be off because the clock showed an outside temp of 94º with the sensor sitting next to the clock in my 75º kitchen. Apparently, the 90s is the only temperature range these clocks can handle. But since I have two excellent remote outside thermometers accurately tracking temps (calibrated agains meterological-grade mercury thermometers), it wasn't something for me to be concerned with. Still, that ostensibly is one of this clock's functions, so one star for the temp reading. That averages out to three stars overall. That's good enough for me, as the temp function was not as critical (and this was still a lot cheaper than a La Crosse without the outside temp function). The big question is how long this clock will last. My La Crosse units last about 10 years (which is why I was replacing one), so that is the record to beat. Build quality seems good on this clock, but only time will tell. And I will update this review accordingly. One final note: These clocks are about half the size of the old La Crosse. To me that's a good thing, since the La Crosse units seemed overlarge. And the time can easily be seen across a room, so readability is not a problem.

Easy to set up. Numbers large enough to read from across the room.

Aside from being practical, this clock really looks nice. I'm using it as a wall clock and it complements the room. The display is easy to read. It has a wide angle of view, you can even read it from the side. The smaller font date and temperature are even readable from 20 feet. Even in dim light, everything is readable. Upon installing the batteries, within 5 minutes, it synced with the atomic clock. It's within 1 second with my phone clock. The signal is strong and constant. I live in Toronto, Canada, and the clock is located in the basement and also far from the window. The indoor and outdoor temperature sensors are consistent with each other when placed close. The difference is no more than 0.5 degrees. I haven't installed the sensor outside as of this writing. I like that this clock runs on batteries, so no cord that ruins the look. Not to mention that it has low battery warning, for both the clock and the outdoor sensor. The manual is clear and comprehensive. I'm happy I chose this atomic clock among so many. It's definitely 5 stars .. so far. UPDATE: To those who are not getting accurate temperature from the outdoor sensor -- it's location, location, location! Read on ... So, I've installed the sensor outside. I stuck it horizontally under the upper member of the window frame to protect it from the elements. I observed the readings for days. I found that the reading is higher than the actual temperature (based on Weather.com). If the temperature is above freezing, the difference is 2-3 degree C. If it's below that, it gets worse. I was very disappointed, and I wanted to change my rating from 5 to 3 stars. But I thought, maybe it's because of its proximity to the window (which is normally warmer since it's heated by interior of the house), and to the ground (since it's a basement window). So, instead, I hung it on the wire fence, which is 4 feet away from the window (not too far to get good reception) and 4 feet above the ground. And voila, I'm getting the right temperature now ! Or at least, within 0.5 degrees C. Since now it's exposed to the elements, I put tape on all gaps, except for the sensor opening, over which I put a hood. I'm still getting the right temperature. It will get only little sun since it's located in the narrow gap between houses. Still, I will observe the effect during high noon. So, I'm keeping the 5 stars. I hope others will learn from this.

Easy to set up and worked with correct time, date and temps the next morning

fonctionne bien a date facile d utilisation

I purchased this clock (CL6006) in July of 2025. The clock works great. I am very happy with its performance. My issue lies with the outdoor sensor which sends the outdoor temperature to the clock. I live in Ontario, Canada, and our temperatures very from quite warm to extremely cold. During the warmer months, the sensor works just fine, but in the colder months, the sensor stops working. The batteries are good, and when I bring it in the house and let it warm up, it starts to work again. Once I put it back outside, it stops working again. I would like to know how I can obtain a replacement sensor.
