Beautiful, upgraded analog clock!
This is a very lovely clock that I needed for my exercise room - it looks very classy on the wall. I had seen digital clocks automatically set to the right time, but I was pretty mesmerized watching the analog clock set itself! It is a great size, easy to read and quiet. I love that it includes places to add two more AA batteries so that they last longer. It has settings for the time zone and daylight saving time option - it set itself to the right time within just a couple of minutes. I am really pleased with this purchase!

Smart clock
I'm obsessed with my new wall clock! It's so smart it keeps perfect time without needing to be wound. Plus, it's super quiet and easy to follow instructions. The size is just right for my wall, and I feel like it was the best purchase I've made in a while better than buying the traditional wall clocks for its design. Simple design and reliable.

This one is 3rd in my Home i am replacing all old one with this wall clock with simple reason it adjusts time automatically during Daylight changes and it runs 100% accurate as it he has Atomic Time Feature conveniently allows the clock to sync with the WWVB radio transmission from Fort Collins, CO, for accurate time updates. Display is nice Nice wall clock to have on your wall

Great but you should know its limit
This clock automatically adjusts itself—like magic! Well, atomic magic. But before you marvel too much, here’s a fun fact: the timing of its synchronization depends heavily on where you live in the U.S. Since there’s only one atomic signal tower (NIST Radio Station WWVB in Colorado), folks in the Pacific and Mountain time zones are living the dream—it syncs all day long. But if you're in the Eastern time zone, especially in New England like me, the clock gets a bit shy. It only tries to sync around 4:00 a.m., like a secret agent reporting in before sunrise. I live in one of those signal-challenged zones, and for a few days, my clock just... gave up. No sync, no glory. Eventually, it caught the signal and adjusted itself—hallelujah! But waiting for it felt like watching paint dry in slow motion. Still, once it locks in, it’s impressively accurate. Overall, it was good buy, just needed a little patience.

Excellent wall clock
A great wall clock. Works perfectly and looks sharp. You can see the time very clear.

A broken clock is still correct twice a day.
Easy to set up. However, I had to search around my house for a location that resulted in reception of the synchronization signal from Ft. Collin’s CO. Once set, the clock is spot on to the second. But when I move the clock to where I want it, it does not get updated consistently. After two days without update, the clock is three seconds two fast. Maybe it’ll surprise me and get updated on its own without moving it again. But I can live with it.

Por el precio no hay nada parecido, yo soy extremadamente puntual por mi trabajo y dependo de relojes exactos para poder desayunar o ir por agua monitoreando los procesos donde trabajo. Estos relojes se ponen solos a la hora, y no es verdad que no puedan ajustarse a Mexico ya que tienen un selector donde no se activa el horario de verano ya que en estados unidos en Arizona no cambia de horario. Esta version usa 2 baterias extra y promete el triple de tiempo sin reemplazarlas. Lo unico que hay que notar es que es un poco menos silenciosa que las versiones mas grandes de una sola bateria.

Just got this clock. Even better then I expected. Simple, classic and stylish. For some reason the wall clock selection in regular stores is very limited. It was not like that few years ago. OK, OK,OK its all Putins fault. Our leaders blame everything on Russia and Putin. Amazon doing amazing , why? Are we in the different countries . Anyway I am happy and really like this wall clock.

Looks great, appears to be very well made. I got it working, and it's keeping perfect time. All I need to do now is wait for daylight saving time and see what happens. I really believe that there will be no problem with the time change because I have another la crosse clock and it works perfectly.
