Sharp Atomic Analog Wall Clock - 12" Black Stylish Frame - Sets Automatically- Battery Operated - Easy to Read - Easy to Use – Modern Design and Style

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.

I love this clock. It syncs to the Universal Time. Due to the WiFi coverage in my house, it didn’t sync at first. But I read the instructions and it said to wait for it to sync in 24 hours. Within 10 minutes it was the correct time. Love it.

Easy to read, perfect timekeeping. I keep finding reasons to buy more of these. So far I have come back and bought two more after the initial one over about a year's time. Can't say enough good things.

This was different. I read the helpful reviews here and when I got it, I put the battery in and watched it run it's hands around and land on the wrong time, so I put it in a southeast facing window and after about 4 hours, voila! Not exactly my phone time but close enough. It looked good on my wall and the time was close enough.And then it started getting dark... darkness is not a friend of this clock. With the black hands, the low light in my living room and the dark gray in the background of the clock, it's like...time flew....right out the window. I could not see what time it was from about 4:30 p.m. until I went ni-nite! And it was not that easy to see in the natural light of daytime! I packed it up and shipped it back. Got one that lights up when it starts getting dark and all is good now.But it's a good clock...

Was using the Amazon clock that syncs to Alexa. It loved to wigg out or chew thu batteries so replaced it with this. This is perfect. It takes some time to sync when you first power it on so have patience... Good things come to those that wait. In about a day it will stay in perfect sync with the clocks at NIST. If you always want the correct time, and are to lazy to deal the setting the time or daylight savings hassles this puppy is for you.

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.

I bought this clock for my sister. She has AMD so her vision is a little blurred. This clock has nice big clear letters nothing fancy. It suits her just fine.

Very pleased with this item.
