Atomic Clock Buying Guide


The materials used in the construction of the atomic clock are important. Most are made out of plastic, but some are made out of metal or wood. But, regardless of the material, you'll want something durable so that it can last for years.

If possible, get something with waterproofing elements. This way, you can put the atomic wall clock outdoors without worry.

Display size

Wall clocks, in general, shouldn't be smaller than 10 inches. Even then, 10 inches is cutting it. Ideally, you'll want a wall clock to be as large as 12 inches. However, if you can get an atomic wall clock with a larger display, then that's even better.

Remember, these clocks aren't on your wrists. They're hung on walls. Because of this, you'll want your atomic wall clock to be large enough to make it easy to tell the time even when looking from the other side of the room.


If you plan on using the atomic wall clock inside your bedroom, we recommend going the digital route.

Digital atomic wall clocks don't make a sound and operate silently. On the other hand, analog atomic wall clocks can get pretty loud. This movement of the hands and the mechanisms can make noticeable noise. This is especially true at night when pretty much everything else is quiet already.

Time zone support

It doesn't matter how accurate an atomic wall clock is. It's not good if it doesn't support your time zone.

Before buying an atomic wall clock, make sure that it supports your time zone. Most can support up to four, so this shouldn't be a problem. However, it would be great if you go with something that can support six or eight time zones. The more time zones your wall clock can support, the better.


Getting yourself an atomic wall clock is a good decision. It helps you stay on time all the time and makes adjusting to [DST](/daylight saving time/) easier. However, you should put a lot of thought into choosing an atomic wall clock.

The best atomic wall clocks are the ones that have the features that you need and come at the price point that you can afford.
