It's a great clock! So glad I bought this one. It looks so good in my kitchen and works perfectly.
This is a great little clock! I had to replace one that I knocked off the wall while cleaning. I have it in the kitchen and it looks so nice. It is very quiet as you don't hear any ticking noise. The size is perfect for any size kitchen and goes with any decor. The one I had ordered prior stated you had to wait 3-7 days for it to anatomically correct the time? I needed a clock for now!

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.

A Clock With Notable Professional Focus
She's a beauty, this clock, as analog as your child's first board-like counting book, round as every Mercator map longs to be, as accurate as your great-uncle's Tag Heuer wrist watch which he wears on Arbor Day and St. Crispin's Day. But to the atomic part: Is it? Well, in that anything, except gravity and Bluetooth, is atomic, yes it is. But to assume that a clock is precise because it is made of atoms is a leap that even a quantum mechanic would be loathe to make. Mine, as an exemplar, keeps pretty good time, and that is all I need. Thanks; I'll let myself out.

Very nice wall clock for the small office
This clock looks really sharp the display is excellent some of the functions about setting the date and time don't really work supposed to hook into time synchronization satellites was never able to get it to work properly I had to manually set it I'm still very pleased with the clock

Easy set up, synched within minutes
Easy set up. Flip over and click the setting to pacific, mountain, central or eastern. Set yes or no for DST. Insert AA battery. Ultimately used on north facing wall but the clock started synching after inserting battery while in the middle of the house, with the clocking lying on a table. Very cool to watch! Hope it lasts and we are done with cheap clocks, also bought here, that last maybe 2 months and then increasingly inaccurate.

Required Clock
Still have it. Bought in 2008. Keeps time to the second and it’s easy to tell when the battery needs replaced.

Does not handle daylight savings change at all
got it in Oct last year (2025), second one of these. Took about 12 hours to lock in to the correct time Both worked fine until yesterday (Sun March-8-2026 Daylight savings time, so here we are at 4:03pm, and they both insist its 5:37pm And thats after 3 resets (at least they both agree with each other!) I'll go back to plain cheap manual clocks

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.
