15 Best Atomic Alarm Clocks Guaranteed to Wake You Up

Before the popularization of smartphones, atomic alarm clocks were a staple appliance in offices and homes. These atomic alarm clocks offer extremely precise timekeeping and designs that look good no matter where you place them. Additionally, they come with a loud alarm that many people argue wakes them up better than a smartphone ringtone.

Although plenty of people today prefer to use their smartphones as alarms, there are others who still use atomic alarm clocks. If you are looking for a highly accurate digital timekeeper for your workstation or bedroom, stick with us as we look at 15 of the best atomic alarm clocks on the market today.

What is an Atomic Alarm Clock?

An atomic alarm clock is essentially a radio-controlled quartz clock that automatically synchronises itself to a time code transmitted using radio waves. The clock typically receives its radio waves from a national or regional time transmitter or multiple transmitters used by satellite navigation systems such as GPS.

After acquiring the transmissions, the atomic alarm clock will automatically calibrate itself to match the time zone it currently resides in. Compared to standard quartz watches and clocks from brands like Citizen, you can say that the atomic alarm clock is slightly more accurate thanks to its automatic time synchronization.
