Accurate, nice looking
I like the clean modern style of this clock, with a ten inch diameter it's a bit small for mounting on a large wall but for my application in a little room and smaller wall in a nook it fit perfectly. The clock functions as reliably as most of quartz movement type battery clocks with the added feature of receiving the WWVB atomic clock signal out of Ft. Collins, CO. making it accurate to within a second every 300 million years. The set up was easy, even though it has an incrementally advancing second hand the clock is silent enough running that I can not hear it within 3 ft which is nice for my bedroom location, the clock is not mounted on an exterior wall or close to a window but still received the WWVB signal within 2 hours of setting up. The knowledge that this clock is synced to WWVB appeals to my sense of science and history of striving for accurate time keeping..... knowing that the clock is associated with the same technology that helps navigate the ships at sea and satellites in space is pleasantly satisfying.

Atomic time doesn’t work
Nice clock

Nice clock bit it's biggest feature (auto set) is finicky
MAR 2025 UPDATE: The radio setting has never worked once in all the time I've had this clock. Still, it does keep time well and looks attractive. I do recommend the clock if you're willing to set the time manually -- but note that "falling back" from daylight savings will be tedious as you wait for it to advance through 11 hours of time. I can't recommend this if you are buying it for the automatic set function. I like this clock. It looks super great and seems to work well. Except one thing -- the auto set feature did not work. I gave it a couple days but it seems like it never acquired a signal. Mind you, this wasn't some room buried deep in the house -- it was in the bathroom with an exterior wall and window. Some are saying you need to hang it a certain way to get it to set -- but that's not a great solution. That means you aren't going to get the time sync and timezone change features of the WWV radio signal when it's finally moved to where you want it. My recommendation is: it's a good clock. Set it manually and hang it. If the auto-set feature works for you then fine, but don't assume it will work right. Maybe someday they'll do a version with a better antenna or RF amp so the auto-set function works well. At the very least, it would be nice if they added an LED to indicate whether or not it has acquired the WWV signal.

Works and great value
So far so good. I was absolutely convinced it would not work properly here. I have an ancient LaCrosse LCD weather station thing (that I love and still works) with atomic time that only syncs about 1/3 of the year. I also have an expensive Casio Wave Ceptor atomic watch that, similarly, can't sync unless I have it in a few certainly places in the house. This clock is not one of those places- an inside bathroom with no windows and on an interior, insulated wall. I am on the mid east coast on the water, and according to all the maps, is one of the worst places for Bolder Co signal to reach (why is it 2013 and there are still no other options for syncing clocks? FM radio, cell signals, TV signals... it is silly there is nothing available that is MUCH stronger and works anywhere inside any kind of building). But this clock? I put in the battery and hung it on the wall at about 8pm, it swept around and stopped. When I went back in the room at 11:30pm, it was magically synced and ticking away and has been for a few weeks now. It is easy to use, easy to read, and doesn't tick loudly. If it gives me several years of service like this, I will be very happy. Can't beat the price. I do wish they had some more designs in their lineup. If it keeps working well, I am probably going to buy some additional units. It is interesting that the minute hand moves in 10 second increments. Most clocks I have seen either move the minute hand in one second or 15 second increments. Probably doesn't matter, just thought I would share that unusual tidbit. One thing- it doesn't sit flush against the wall as you might think it does from the stock photo, since the clock "brain" and battery box is in the back.

This does not work in Australia and the manual set is WAY to had to set accurately.

Este reloj tiene conexión automática con el reloj atómico de Colorado; en mi caso no logré que se conectara automáticamente con el mismo, por lo que lo tuve que sincronizar manualmente y hasta la fecha casi un mes, esta muy exacto y sin problema alguno. En teoría una vez sincronizada la maquinaria, solo se ajusta; tienes que seleccionar tu zona del tiempo y trae un interruptor para activar-desactivar el horario de verano donde en algunos países no se aplica, por ejemplo la Ciudad de México.

Nice looking clock but does not auto set for countries outside of the US. As such a bit pointless for UK market.

Relógio muito bom, não precisa ficar acertando as hrs, ele se ajusta automaticamente, inserir pilhas de boa qualidade, eu tinha um outro e tinha que ficar trocando e ajustando sempre, e este não precisa fazer estes procedimentos, sómente quando acabar a energia das pilhas, ótimo produto .

I bought this clock because of its simple design and not to ever have to worry about the correct time again. It works and receives the U.S signal up in Toronto. It does automatically switch to daylight saving time twice a year which is great. However that requires the (one time) switch of a button on the back of the clock, No major inconvenience but something one needs to be aware of.
