    • So nice, I bought it twice
Color: Black / White
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 set 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 five or ten minutes. It still tracks minutes perfectly, but from :00 to :05 or :10, 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. ... show more

    • Great Clock
Color: Silver / White
Operates as.described. Easy to setup. Looks great on the wall! Easy to read with the large numbers. This was a purchase for my mother’s apartment. It looked so nice we wanted to purchase another one for ourselves. The “Atomic Clock “ means you never have to reset it.

    • Works perfectly, except...
Color: Silver / White
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. ... show more

    • Easy set up, excellent legibility, expectation of long term reliability based on prior experience
Color: Silver / White
This clock set up automatically overnight exactly as the instructions indicated it was supposed to. It is installed in our kitchen in an easy to view location. Although it does not have luminous hands and dial for night use, the bright white dial and high contrast black hands allow it to be read in low light. Based on experience with another Sharp atomic clock still running flawlessly for over 20 years and counting, we expect this clock to prove to be very reliable. ... show more

    • Absolute garbage. Sets wrong time, randomly varies. Can't be set manually, can't be fixed.
Color: Silver / White
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. ... show more
