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 Review: Good purchase - updated Oct 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. ## Features - Accurate Atomic Clock: The atomic clock has a built-in receiver that automatically synchronizes itself with the WWVB radio broadcast, which will update time automatically every midnight to ensure accurate time. It has 4 time zones: EST, CST, MST, PST. (No Backlight) - Atomic Clock with Indoor and Outdoor Temperature: This atomic clock can display both indoor and outdoor temperature, helps you better manage your daily life. The wireless outdoor sensor monitors and transmits the outdoor temperature to the clock to display.

Both of them could be turned off manually if for no need. With DST on, clock will go forward or fall back one hour automatically in daylight saving time - Large Display with Temperature, Day and Date: The clock shows time with seconds in big bold in the middle of screen, help you read the time easily and quickly. It also displays indoor temp/outdoor temp/day/date on bottom, provides a full information you need on clock - 12/24Hr Time Mode and Fahrenheit/Degree Switchable: This atomic clock has two display modes (standard time and military time). When clock time is set for one mode, the alarm time would be followed same automatically.

Here's my take on this 12.5-inch self-setting digital timepiece. Precision (5/5): The standout feature of this atomic clock is its unparalleled precision. It synchronizes automatically with the atomic time signal, ensuring that you always have the exact time down to the second. This feature is not only convenient but also essential for tasks that require precise timing. Setup and Installation (4/5): Setting up the WallarGe Atomic Clock is relatively straightforward, thanks to the detailed instructions provided. However, it's important to note that it may take a bit of time for the clock to sync with the atomic signal, especially if you're in an area with poor signal reception. Once synchronized, though, it maintains accuracy flawlessly. Temperature Monitoring (4/5): The inclusion of both indoor and outdoor temperature sensors is a handy addition. It provides real-time temperature data, allowing you to make informed decisions about your indoor climate and outdoor activities. The only minor downside is that the outdoor sensor's wireless range may be limited in some situations. Display (4/5): The large, clear LED display is easy to read from a distance, even in low-light conditions. The digits are bold and well-illuminated, making it effortless to check the time and temperature at a glance. The clock's 12.5-inch size also makes it a standout decorative piece. Design and Build (4/5): The WallarGe Atomic Clock boasts a sleek and modern design that complements various home or office settings. The build quality is decent, but it could be improved to feel sturdier. Nevertheless, it does not compromise its functionality. Battery Backup (4/5): The clock includes a battery backup feature, which is essential in case of power outages. However, the backup battery is not included, so you'll need to purchase one separately. Value for Money (4/5): Considering its atomic timekeeping, temperature monitoring capabilities, and large display, the WallarGe Atomic Clock offers good value for money. It's a versatile addition to your space, especially if precision and temperature monitoring are priorities. Conclusion: The WallarGe Atomic Clock with Outdoor and Indoor Temperature is a reliable timekeeping device that offers precision, temperature monitoring, and a sleek design. While it may take a bit of time to initially synchronize and could benefit from a sturdier build, its features make it a valuable addition to any home or office. Whether you need precise timekeeping or want to keep an eye on temperature fluctuations, this atomic clock delivers functionality with style. ## Frequently Bought Together - WallarGe Atomic Clock with Indoor Outdoor Temperature - 8.5'' Digital Clock Battery Operated, Self-Setting, 4 Time Zones, DST - Nail Growth Serum, Ginger Nail Serum, Nails Repair Cuticles Oil, Ginger Nail Oil for Strengthen & Promote Nails Growth, Natural Plant Formula - 12 Pack Mouse Repellent Natural Peppermint Oils Rat Repellent Pouches, Mice Repellent --- ## 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.sk/products/535794344-8-5-digital-atomic-clock-with-indoor-outdoor-temp-battery](https://www.desertcart.sk/products/535794344-8-5-digital-atomic-clock-with-indoor-outdoor-temp-battery) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-07-25*
