## Description

atomic clock with indoor outdoor temperature

Review: Bought this to replace a very old clock that had to be adjusted manually every time the time changed or the battery needed changing. I liked it tho because it had a backlight. Wishing this new one had a backlight - it it did I would give it 5 stars. Very easy to setup and use.
Review: I recently purchased the WallarGe Atomic Clock and have been extremely impressed with its performance. The self-setting feature works flawlessly—right out of the box, it synchronized with the atomic clock signal, setting the correct time automatically. I no longer have to worry about adjusting for Daylight Saving Time (DST), as it updates on its own. The indoor and outdoor temperature display is a fantastic bonus. The outdoor sensor paired effortlessly with the clock, and the readings are accurate within a reasonable margin. It’s really convenient to check the temperature before heading out. I also appreciate the large, easy-to-read display. Even from across the room, the time, date, and temperature are crystal clear. The fact that it runs on batteries makes it incredibly versatile—I can place it anywhere without worrying about outlets or cords. I would say it would be a great improvement to make it backlit to show up in the dark would be nice. However, I am sure the batteries wouldn’t last as long. Overall, this clock is precise, reliable, and easy to use. If you’re looking for a self-setting wall clock with temperature tracking, this is a great choice. Highly recommend!

*by G***S on 11 May 2025*

The set up takes time . You have to set up time year am or pm etc. I could not find year. You have to hold down a button the move to up and it blinks through each parameter . It’s not for the faint of heart or those who want easy quick gratification . I like the clock but it takes dedication to set it up. I had it on pm so the day was wrong in the morning . The set up of the year sets the day. I almost quit set up because of that too.
