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 synchronized with the main atomic clock in Boulder, Colorado, which uses the resonance of atoms to keep accurate time.
Advantages
The main advantage of an atomic is that it gives incredibly accurate time. They are very small and easy to work with. Most come with battery backup so you don’t have to worry about them turning off when there’s a power outage.
There is no need to adjust the time! Atomic travel alarm clocks do that for you. Of course, 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 your watch to them. That’s why those non-radioactive atoms are used in atomic travel alarm clocks. One of the usual 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 operated. Although we have batteries today 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 cool, but do you really need them in this age of internet-enabled cell phones and super dumb watches? Still, some people prefer to use travel watches instead of a phone or alarm clock because the buttons are bigger.
