    • Easy, accurate and quiet
Size: 12.5 inch
Setup can't be easier if you live in the Eastern Time Zone. Just install 3 fresh batteries and wait for the clock to receive the NIST signal. The clock I bought was able to connect during daylight hours at North Carolina. The display is big, bold and easy to read even in dim light. You expect the time displayed by an atomic clock to be accurate, and it is. The clock's temperature and humidity displays are also very accurate. Operation is silent, so this clock is good for any room. I put the first one in a bedroom, and I have a 2nd clock in my shopping cart for another bedroom. ... show more

    • Sets Itself Fast and Accurately
Size: 8.5 inch - Black
I purchased one of these a little over two weeks ago to evaluate it for a few locations in my house, then purchased another one 4 days later. The clock is accurate and set itself so quickly after I put the batteries in that I didn't have time to read the instructions to set it. I have a watch that sets itself automatically and they matched, so I'm sure it is accurate. The clock has large numbers and is easy to read from a distance as long as there is some light in the room. My only negative comment is that I wish it had a corded version with backlighting, so it could be read in the dark. I don't know how long it lasts on the batteries, and that of course is another important consideration, but clearly backlighting would not be practical for this battery-operated timepiece. ... show more

    • Very pleased!
Size: 12.5 inch
I ordered two other clocks and I have had another for years. The problem with all three was the fact that the time was not always clear due to a glare where you could see parts of the other numbers (for example you could see parts of other numbers that make a 2 look like 8). And you could not see time from all angles. And some were too small. This clock does NOT have any of those problems. No glare. Time is crystal clear from all angels. And the display is large. Just right! Very happy I finally found a good one! Just wish it were black and silver. ... show more

    • Back for another one ...
Size: 12.5 inch
UPDATE on 6 Mar 2024: Sad to report, but the second clock I ordered is giving me problems. It will automatically set and everything will work fine for a while ... but then will malfunction to a different date/time, etc. I've had to reset it twice. Will update. ORIGINAL I’ve never been a clock watcher. I’ve been retired since 2004 and primarily operate on a Winter/Spring/Summer/Fall timeframe rather than a day-to-day calendar. However, I do a lot of genealogical research so I never know what century I'm in ... let alone the day or month. Add to that my aging brain and I'm to the point where I need some help. After putting the trash out on the wrong day, I finally realized I needed something to keep me grounded. So, I purchased this clock. It was easy to operate ... just added some batteries and the clock set itself. Has kept time perfectly. I guess one point of concern ... for me ... is that it is too large for my bedside table. So, I put it on my dresser. I have a small alarm clock I use for bedside. Even so, even at night, and across the room, I can see this clock well enough to read the time than I can my bedside alarm clock. I have small light source in my bedroom at night for one of my cats who is visually impaired. (My bedframe has a wonderful light that lights up under the bed – love it!) Anyway, it provides enough light that I can see the time on this clock. My bedside alarm clock is another story. To see it I have to press a button on the clock to see it. Everything really was better in the 60’s! Miss those clocks where the numbers and the hands of the clock glowed. So, I’m back to purchase another clock to put in different part of the house … for those times when I forget the day or date! Now, I won’t have to run back to the bedroom to look. ... show more

    • Large time font and works for Atomic radio
Size: 12.5 inch
This clock works great and picked up the WWVB signal quickly and set the time. The time is in big font, making it readable from a distance. Satisfied.

    • If it's sold as atomic, it should at least be accurate, right?
Size: 12.5 inch
I'll comment on two aspects of this clock: the atomic function and accuracy. Since it's sold as an 'atomic clock', I'll start with that. Atomicity ------------ I received this clock 12 days ago. I live in a top-floor apartment in a 3-floor building somewhere on the west coast of Los Angeles County, California; only around 880 miles from Fort Collins, Colorado. That's where the National Institute of Standards and Technology (NIST) broadcasts the 60kHz WWVB atomic-clock-based time radio signal. That signal has a 2000 mile radius and covers the entirety of the contiguous United States and reaches significantly large parts of Canada and Mexico. The building where I live doesn’t have a lot concrete or large metal structures; there isn’t a single tall building in the way between the clock and the low hills looming in the horizon; there’s no source of significant interference— powerful electric motors, high power lines… etc— nearby and the weather’s been beautiful those past 12 days. In short, as far as sight, I have clear near-line-of-sight to the source, and there’s nothing to cause poor reception. I’ve even used a compass and map to get the best directional cue after the first few failures. Yet, it seems a tall order for junk manufacturers to make products to receive the signal under these near-ideal conditions! I wonder if they even test their products in the US at all, the US being the only consumer, let alone test a statistically representative sample of locations within each state. First off, when I turned it on it, it did not receive the signal. I tried getting it to manually sync by pushing the WWVB button and waiting for it until it gives up— after 7 whole minutes, several times, including in the balcony, to no avail. It was very frustrating! Over the next three days I tried several spots and it would always fail, both manually and automatically. BTW, this clock and most of its ilk, like the not-as-bad 'Sharp' I purchased about 6 months ago, attempt to auto-sync several times late at night. According to this clock’s manual, it attempts the sync hourly for up to 3 times, starting at midnight. On the 4th day, I noticed that it had 'magically' synced. I noted the ‘sweet spot' where it did and kept it there until the 10th day. Throughout those 10 days, it was a hit-and-miss. However, it auto-synced in the ‘sweet spot' the last 3 days— of 10— in a row. On the 10th day, I noticed that time had jumped 40 minutes forwards, despite the indicated successful sync… just like that! And that's when I decided to return this piece of junk. Just for the sake of completeness, I found the ‘sweet spot' to be a tiny 2x2ft area on, and within a few inches off, a specific wall, and much lower than where one would normally hang a clock. Furthermore, manual syncing in the 'sweet spot' at an arbitrary time of day doesn’t work! So, it’s only auto-syncing that works, during the night, and only in the 'sweet spot!' Accuracy ----------- The magical 40-min jump aside, I noticed that without syncing it would gain nearly a full second daily (~0.9.) That's about 5.5 min ayear. The manual even specifies 'free run' accuracy as ± 60 seconds, per month! Is that acceptable from ANY timepiece in this day and age? I don't think so. It means this clock uses possibly the cheapest oscillator out there. In this regard, the 'Sharp' I already have loses— instead of gains— about 0.7 second per day; it uses a cheap oscillator too, just not as bad! Worse yet, even when it does sync, it doesn't correct the ~0.9 second it had gained the day before! It seems that it's either designed to ignore minor drifts, or the ~0.9 second drift is itself one of the, many, design flaws. Either way, what's the point of ‘atomicity’ when accuracy isn’t a design imperative? Notes ------- · The clock indicates successful syncing by the 3 curved lines (called “wave” in the manual) appearing above the fixed triangle (called “radio tower” therein.) · Gain and loss estimates are best-effort, and based on visual comparison with time display on a computer which syncs 3 times per day with NIST's NTP (Network Time Protocol) time servers. · The 'Sharp' I have has a similar 'spotty' syncing problem; it, too, has a poor WWVB radio receiver. Unfortunately, it worked somewhat acceptably in the place I was before, and my return window has closed many months ago. Apart from the weak receiver and oscillator unbecoming of the brand name, it's rather nice and sturdy, unlike this one. It supports up to 3 outdoor temperature sensors; it comes with only one, though. It's just not worth the $65 I paid Amazon for it, on account of the weak receiver. For reference, here it is: https://www.amazon.com/dp/B08S31FRDQ?ref=nb_sb_ss_w_as-reorder-t1_ypp_rep_k0_1_9&=&crid=YK3RQ60CQKOD&=&sprefix=sharp+ato · If you think you can live with manually setting clock, think again! This clock— and most of the ones of its ilk that I've checked out on Amazon— seem to have the design flaw of assuming it will successfully sync most of the time. Thus, their designers seem to pay little attention to how it will be set manually. There are only 2 buttons: Up and Down, to set just the hour and minute. The same butons are used to set other date components using the “Time Set” button to switch contexts. If you don't have nimble fingers and lighting-fast reflexes, you'll find it very trying to correctly adjust time to the second. And given how quickly in runs adrift, you'll probably have to go through that several times in a week. If you care for accuracy at all— as you should be if you're considering an atomic clock, you'll probably find it easier to just 'walk it' like a dog for up to half a mile to find a place where manual syncing succeeds! It's ironic really, it's a clock— an 'atomic clock', mind you— yet designed as if it were to be incorporated into a stove or microwave oven as a supplementary function! ... show more
