SEIKO 12 Inch Radio Wave Wall Clock

This clock is fabulous! It adjusts the time according to radio waves so no messy turning of little dials in the back. It was so easy to set up - put in the single AA battery, leave it next to a window for a few minutes, hang it on the wall! It has accurate time and it is the easiest clock to read of any we've ever owned (we've owned a lot of wall clocks!) The design is simple, clean and modern. We absolutely love it and highly recommend --

Nice clock, #2 for me and it synced in the PST PACNW zone in under 30 minutes. While not made of gold and silver, it does work well, is easy to read, and in our living room, if it ticks . . . I'm not hearing it. Clock #1 was a gift for a friend.

Our previous atomic wall clock, by Lacrosse Technologies, lasted just short of two years before the second hand stopped working. The quality of that item was never very impressive. Contrast that with this new Seiko clock. The mechanism in the back is more robust, easier to understand, and this clock synced with the atomic clock in Colorado almost instantly in the middle of the day.Some have complained this Seiko clock ticks loudly; not true. If the room is completely silent, and you strain to hear it, the ticking is detectable but otherwise not at all intrusive. The look is elegant, with silver background and black numbers. Very satisfied.

Very classy clock that can fit in with many decor styles. Easy to set up and seems to be doing it's job just fine.Pros:+ Atomic clock synchronization (granted your location can receive the signal)+ Decent battery life, especially when using high-capacity rechargeable cells+ Simple and elegant hands/numeralsCons:- Overpriced (despite being an atomic signal clock, it's completely made in China)- Ticking hands instead of sweeping- Ticking can get noisy; quieter than many clocks I have experience with, but for this price it shouldn't be that loud- "Invisible" seconds hand; no contrast with the dial, so it's almost impossible to see- Manual setting time is done per minute, so it can take a whileVerdict: I would recommend it only if you can find it for much cheaper. Honestly NOT worth what I paid ($51) considering it's ticking, not sweeping, seconds hand and that it's completely made in China.

The University of Miami purchased a few of these for our classrooms. They were suppose to synchronize by themselves to the time, and never did. It's important that they self synchronize as we have the time changes throughout the year. I guess they could not get the signal, however the Maple atomic clocks worked perfectly.

Aesthetically pleasing clock. Did not auto adjust correct time immediately, but after about 24 hours, has been accurate to the minute, keeping in sync with time on smart phone. Numbers are large enough to view time from a distance but not too big.

I just bought this clock without knowing what the R-wave technology is about. The specs for the clock on this Amazon site doesn't say that time zone settings are for continental USA only; I live in Hawaii so the closest time zone I can get is Pacific Standard Time. I like the appearance of the clock and would like to keep it if I could disable the automatic time sync-ing and not have to keep re-setting the time. I have been searching online to see if there are instructions but I have yet to find any so I am disappointed that I will have to return the clock or learn to adjust to the different time zone. I do agree with other reviews that the numbers do look blurry when viewing the clock from an angle but the blurriness at an angle is not a big deal to me.

I have had unit for 2 days. Quick synopses: After putting the battery in this clock (AA was included box), I followed the instruction and set the time zone, DST (on) and hung it on the wall. Within 10 minutes, the clock wound itself to the correct time. From a functional standpoint, the R wave thing seams to work well.1 star off for 2 things.#1 The clock second hand makes a ticking sound, which is only a little quieter than the $10 clock I have from Target. I would have expected it to be more quiet. If you live in a 2 bedroom apt, you will notice the tick it the clock is in your bedroom, but it would not keep you up at night.#2 I though I wouldn't mind the print being on the clear plastic face of the clock, rather than the back face and behind the hands, but I was wrong. The numbers cast a shadow, and it's not something I like about it. Not really a deal breaker, just wish it was more traditional.Overall, I like the clock. However, with so many other options available, I would not likely buy the clock again.
