What is an atomic travel alarm clock?
First of all, they are not linked to the atomic bomb in any way.
The only reason to call them atomic is that they are in time with the main atomic clock in Boulder, Colorado, using atom resonance to keep accurate time.
Advantage
The main advantage of an atomic is that it provides an incredibly accurate time. They are very small and easy to work with. Most will come with battery backup so you don’t have to worry about them shutting down when there’s a power outage.
You never need to set the time! Atomic travel alarm clocks do it for you. However, you have to set the alarm. This is because atomic clocks work more like radios than clocks. They tune in to the huge atomic clock in Boulder, Colorado. They actually use the resonance of atoms to tell time instead of little gears and levers.
Some atoms resonate so predictably that, well, you can literally set them on your watch. That is why those non-radioactive atoms are used in atomic travel alarm clocks. One of the common atoms is cesium-133, which always resonates at 9,132,631,770 cycles per second. What this means is that you get a very accurate travel alarm clock.
Disadvantages
The main disadvantage is that atomic travel alarm clocks are battery powered. Although today we have batteries that are very durable, they do not last forever.
Another disadvantage of these watches is that they cost more than other types. Sure, they look great, but do you really need them in this age of internet-enabled cell phones and super duper watches? Still, some people prefer to wear travel clocks rather than a phone or watch the alarm because the buttons are larger.
