Atomic Analog Wall Clock - 12" Silver Brushed Finish Sets Automatically- Battery Operated Easy to Read Use: Simple, Style fits Any Decor

Update with video April 1, 2026: Video showing the second hand stopped. The background noise is not the clock but a pump 😅 Original: I have two of these Sharp Atomic clocks and honestly love them. I really hate resetting clocks for daylight savings (why is that even still a thing?) and these set themselves. I have two notes though. The first is that they tend to reset themselves in the middle of the night. I work nights, so looking up to find my clock spinning around like it's possessed is a little strange, even after several years. The other thing they both do is in the middle of the night, at the top of the hour like 1, 2, or 3 am, the second hand will stop at 12 for a few minutes. It still tracks minutes perfectly, but from :00 to :04 or so, the second hand is frozen at 12. I have no idea why they do this, couldn't find anything about it anywhere on Google. But, it resumes and keeps perfect time, so it's just an oddity. I'm pretty sensitive to ticking noises, and I cannot hear this clock tick unless my head is right next to it and the room is quiet. 15 feet away on the wall, I don't hear it at night at all, ever. It's a good size I can see across a fairly large room in my home (open floorplan), but isn't enormous or anything. Very simple, classic looking, easy to read clock face too. I'm poor and $40 is a lot for a wall clock. But I don't have to get out a ladder and reset the damn thing twice a year and I find that cost was absolutely worth it to me.

Very happy with this clock. It does take a while for it to find the atomic signal and sync to the correct time but you just need to be patient. I have 2 of them in my house and they are both accurate. The glow is decent but if it's in an area with less light it obviously doesn't glow as well. The numbers are easy to read even at night. It is not a silent clock it does make a deep tick but it's not loud either. Overall a great clock and I would definitely buy more again in the future.

Update: I liked the first one so much, I ordered another one with a gray face! If there's one thing I love, it's a functional item that makes my life easier. I hate going around the house twice a year at Daylight Savings time to adjust clocks. This eliminates that! This one is easier than other atomic clocks I've had as well. I just inserted a AA battery, and a few minutes later the clock was synced to the exact time down to the second! What could be easier? It is the perfect size for my kitchen, and is very light so mounting was easy. The large numbers and split hands are both stylish and easy to see. In all, a great value!

Keeps excellent time, but the hands are hard to see. Plus, the 'glow in the dark' claim is only valid if you spam the thing with a massive spotlight for two minutes.

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.

This black wall clock is exactly what I was looking for. The simple, modern design goes perfectly with any décor and adds a nice clean look to the room. The numbers are large and easy to read, even from across the room, and the contrast of the black background with the white hands makes it very clear. It’s lightweight but sturdy, and mounting it was quick and easy. The clock runs silently—no annoying ticking—which is a huge plus for bedrooms or offices. I’ve had it running for weeks now, and it keeps perfect time without needing any adjustment. If you’re looking for a functional, stylish, and affordable wall clock, this one checks all the boxes. Great quality for the price!

Awesome. Glows in dark and atomic feature keeps it accurate with no help from me

The Sharp "Atomic" clock works as advertised. It receives a time signal via radio from station WWVB at the NIST lab near Fort Collins, CO. A small computer chip in the clock decodes the time signal and uses it to set the hands of the clock. The clock operates silently -- no ticking noise. NIST is the National Institute of Standards and Technology, part of the Commerce Department. The user guide for the clock says that I might need to try positioning the clock on different walls to properly receive the time signal. This was the case for me -- I had the clock on an east-west wall to begin with, and it did not "sync" that first night. I moved the clock to a north-south wall and the second night it synced successfully. When I looked at it the next morning it was displaying the correct time to the second. The user guide also says that signal reception is best at night and that it might not receive a signal during the day. I found this to be the case, too -- the clock did not sync during the daytime. Note that this clock model supports only the four main US time zones: Eastern, Central, Mountain, and Pacific. You set a selector switch in the clock to one of these zones. You also set a switch to tell it to adjust for US Daylight Saving Time or not, depending on your area. If you can't describe your location using these two switches, the clock won't display the correct time. It's really just for US locations in those four time zones and US Daylight Saving Time rules. I recommend the clock if you are located within the area for which it's designed. I particularly like the silent (non-ticking) feature. That works perfectly, and it's the reason I picked this model instead of one of the others. If a clock's description doesn't specifically say that it operates silently, then it probably isn't silent. There's nothing wrong with ticking, it's entirely a user preference, but I wanted silent operation.

Relogio muito bom e muito bonito. Tamanho perfeito. O único detalhe negativo é que não foi possível atualizar automaticamente as horas.

Works well. I get good signal from WWVB where I live in Southern Ontario. Clock is bang on every day.

Pour l'instant cette montre murale fonctionne très bien. Suivi les instructions et il est vrai la nuit les aiguilles sont bien éclairé.

nice clock not to fancy works great always stay on time .great after power outage

Muy bueno, pero no lo dejen en el sol para cargarlo, el vidrio funciona como un lente y quema el plástico donde vienen los números, ahora mi reloj está todo chueco. En ciudad de México se tardó como 2 días en sincronizarse.
