The Atomic Clock will always be accurate to within one second as it receives daily WWVB updates.
- AUTOMATICALLY SETS: Clock resets regularly by radio-control to match the US Atomic Clock in Colorado and adjusts automatically for daylight savings time
- BRUSHED SILVER FRAME: Brushed frame adds style and longevity to any decor
- BATTERY OPERATED – (Requires 1 x AA batteries – not included)
- EASY TO READ – EASY TO USE: Simple, easy to read style fits any decor and is easy to read – perfect for any room in the house: den, office, kitchen, kids room, garage

This thing is total garbage for any price, much less $40, and yes I followed all the instructions. I thought I was paying extra to get something with quality control. Boy was I wrong.
When first given batteries, the hands spin for about 3 to 10 minutes to put all three pointed at 12. That works, all hands find 12, which tells me the hands are installed correctly.
The clock does find the radio signal, because a few minutes after doing the startup “reset dance” to 12, it will start spinning again to set a different time. All pretty normal, it’s using holes in internal cogs to figure out where the hands are.
Problem is, it sets itself randomly from 3 hours to 2 hours 40 minutes late for every time zone it can select. If it’s 12 Pacific time and you select Pacific time zone using the switch on the back, it sets itself randomly between 2:45 and 3:00. If you select Mountain time, it spins to 4:00 when it’s actually supposed to be 1:15. Central, it’ll go to 5:00 (when actually 2:15) and Eastern 6:00 (when it’s actually 3:15).
The minutes hand inaccuracy seems to randomly vary within a 20-minute range each time I tell it to re-synchronize with the radio signal, so you can’t even just remember how far off the clock is and compensate.
I found the hours hand can be spun on its fitting to fix the hours, which is in itself awful but at least helps fix it. Unfortunately even if I got the hours to set correctly from Fort Collins, that random 20-minute variance in the time setting means it’s impossible to know how far off the clock is on any given day.
The specs say the material is “Silver” which is usually an ‘advertising lie’ that means zinc, steel, chrome, or some kind of metal or metallic finish. Nope, all plastic with an ugly gray paint, and that plastic isn’t even nice plastic. It feels like that soft bendy plastic they make Halloween pumpkin candy baskets out of.
As I typed this out I tried using the ‘Wave’ button on the back one last time just to be sure. This forces the clock to reset and look for the radio signal again. It did the same thing as the four other tries. All hands go to 12, then it sits for a few minutes, then the hands start moving again. They spin up to the current time, then blow right past it and stop 3 hours in the future. Except this time the minute hand went to a time that’s 15 minutes slow.
Well, what if I just don’t use the radio setting (that was the whole point of paying $40 for a clock)?
Nope. Here’s how you set it. There’s one button you hold down, and while you’re holding it down, the minute hand spins. It will only go forward, not backward. When you let go, it stops spinning. And then if it does detect the radio signal again, or whenever you have to change the battery, it will go back to the incorrect time.
That means,
* If your clock is 5 minutes fast and you want to correct that, you have to hold the Set button down for 10 minutes while the clock slowly spins through all 11 hours and 55 minutes.
* If you overshoot that, you have to do it again.
* If it ever hears the radio signal, it will reset to the incorrect time and you have to do it again.
* If you change the batteries, you have to wait 10 minutes for it to spin to 12, wait 30 minutes for it to hear the radio signal, wait another 10 minutes for it to spin to the time it heard, and then hold the Set button for another 10 minutes to spin it manually, for a grand total of *it takes an ACTUAL HOUR to manually set this clock after changing batteries.*
Whoever designed this clock is a sadist. Please, do yourself a favor and get something else. It’s impossible to make a clock worse than this, so anything else you buy will be better.

It is great to get a product that operates as advertised! The clock updates daily and did everything that the instructions said it would do. No setting required other than flipping switches on the back that indicate your timezone and if you want daylight savings. Other than that, just insert the battery. Looks great and is easy to see!

No, it’s not actually atomic (no China Syndrome risk here), but it does link to clocks that are. I got this as a Christmas gift in ’22 and found that indeed it keeps perfect time, within a tiny fraction of a second of my cell phone. The single AA battery went a little over two years, and once replaced, the clock (eventually) reset itself to the correct time again. With the black hands on the white face, this clock is super legible, even from across the room when I don’t have my glasses on. It’s a bit pricy compared to non-atomic clocks, but I love accuracy, so this clock is perfect for me! Highly recommended.

É um relógio bonito mas por ser atômico deveria ser mais preciso e isso ele não é. Ponteiros vieram desalinhados e no meu caso ele sempre sempre está adiantado 1 minuto. Já o ponteiro dos segundos não está em sincronia com o horário dos relógios oficiais. Não vale o investimento. Deve existir relógios atômicos melhores.

It worked as advertised .Very happy .

Clock has been in use, with perfectly accurate time, since April 2022 – almost two years. It is easy to read. Adjusts automatically to those annoying twice-a-year time changes. However, this morning, the second hand was still working properly, but the time reported was about three hours off. It’s been two years, so I changed the battery, and the clock hands began spinning around and stopped at 12 o’clock. I took out the battery and put it in again, and this happened again, several times. Right now I have it sitting in a south-facing window, hoping it will respond to radio signals and re-set with the atomic clock in CO. For now, it sits stationary at 12 o’clock. I will amend this review to update whether or not the clock resets properly or just stays at 12 o’clock. Seems to be trying to reset – says 12:10, which is an hour off the correct time of 11:10. Maybe it’s trying to adjust to Daylight Saving time twelve days early? Added a few days later: I put on magnifying glasses and read what the little buttons on the back say. I pushed reset, and made sure the slider was pointed to Pacific time, and turned off the DST button. The clock again spun around, but a few hours later was at the correct time in this time zone, and has stayed at the correct time since. What will be interesting to find out is if the clock will automatically switch to DST in 11 days, as it has in the past. Great clock. Buttons on the back are difficult to read.

I ordered this product May 2024 and it is working great as of 10.2024. Tells time very accurately, easy to read, and fairly attractive. It automatically adjusts to the time change due to Daylight Savings Time, which is so helpful. Pretty lightweight. I liked my previous “Atomic Clock” (different style) which lasted about 20 years, and this is a very good replacement. Helps me know the time!!!

Its not Sharp Atomic, its AIMS Quartz Wall Clock.

There is a low level noise I heard one night that sounded like my toilet was running, turns out it was the sound of the clock ticking. Instructions say to hang on a wall near a window and it will set itself my morning. That is just what it did! Timekeeping is perfect, hand movements are on spot, face is large and clear to see at night. Functions beautifully. I am so impressed with my new Sharp wall clock and highly recommend this product.

We love the modern look of this clock with its gray background. However, as everyone said in the review, it wasn’t easy to see the time when mounted on the wall. Initially, we considered returning it but decided to paint the hands with a white permanent marker, as shown in the first photo. This made the visibility much better and the clock looks even better with the white hands.
Despite this issue, we love the atomic feature of the clock. Still, to the product managers and designers, please take note: we don’t need the entire clock to glow in the dark. A modern clock with a gray background and white handles would be perfect. @sharp, please incorporate the overwhelming customer voices.
