Featuring large, easy-to-read digits and a wireless outdoor temperature sensor paired with an indoor sensor, it delivers precise time and temperature data. Battery powered for cordless convenience, it supports multiple time zones, 12/24 hour formats, and daylight saving adjustments, making it ideal for professional and stylish home or office environments. ## Description Atomic Clock? This atomic clock is an extremely accurate timepiece. It can receive the time signal transmitted by the National Institute of Standards and Technology (NIST).The NIST broadcasts the time signal (WWVB,60KHz) continuously from Fort Collins, Colorado. This signal can be received anywhere in the continental USA and Canada. It is expected that the signal can reach a distance of over 2,000 miles from the transmitter. This WallarGe atomic clock automatically receives the time signal every day at midnight and makes any required adjustments to the time setting. Simply insert the batteries provided with the clock and it will synchronize to the time set out by the atomic clock in Colorado once the signal is received. The clock includes all 4 time zones. The time and date can easily be set manually for those using the clock outside of North America. Daylight Savings Time on/off option is included. Fashionable sensory design, large LCD digits display and multiple visual angles make it suitable for all occasions: Banks, Schools, Churches, Offices, Livingroom,Bathroom and Kitchen. Review: Better than expected ... so far. - 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.

Is there a way to make the numbers darker?** A: NOPE! No illumination or contrast adjustment settings. It’s like an old classroom calculator. If it’s in the shade, it disappears. **Q: How close to an outside wall is needed for the clock to receive time radio signal? (East Coast location)** A: My clock is not hanging near an outside wall. It is on an inside wall facing my front door and large window about ten feet away. It seems to catch the radio time signal with no issues. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Better than expected ... so far. *by G***E on 26 January 2025* Aside from being practical, this clock really looks nice.

I like to display on the newer model very easy to read very easy to set up and seems to be accurate. Price was good too ### ⭐⭐⭐⭐⭐ Good purchase - updated Oct 2024 *by D***A on 19 March 2024* 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. ## Frequently Bought Together - 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 - Duracell Coppertop AA Batteries with Power Boost Ingredients, 24 Count Pack Double A Battery with Long-lasting Power, Alkaline AA Battery for Household and Office Devices --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/460042456-wallarge-atomic-clock-with-outdoor-and-indoor-temperature-12-5](https://www.desertcart.gr/products/460042456-wallarge-atomic-clock-with-outdoor-and-indoor-temperature-12-5) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-21*
