Flashback of the Alarm clock:

The rising sun has helped people wake since the beginning of time. The morning crow of the rooster has helped people to wake for centuries. That has definitely been the most annoying alarm clock…if he didn’t stop. People used to drink more water at night to go to the bathroom early in the morning.


Around 1500 BC, one kind of clock was used, namely ‘Sundial’ is an ancient clock. It had a simple design that was based on the shadows the sun cast as it moved through the day. The popularity of it never decreased even with the invention of mechanical clocks.

Water Clock:

The Water Clock helped the earliest civilization to tell the time of the day after the sundial.  Plato used It for the purpose of alarming his morning class.

First mechanical clock:

Cetesibius the man of Alexandria developed the water clock and invented it which worked mechanically. The whistle-like sound marked a specified time.

Advocacy of Roman: 

Cassiodorus, the late Roman statesman, felt the utility of the water clock and advocated in his rule book. A rhetorician, Procopius described a complex public striking clock that featured an hourly gong moving mechanically.

Invention of Chinese:

Yi Xing (683-727), a Buddhist monk invented a striking clock. Later on two Engineers Zhang Sixun and Su Song from china assimilated striking clock and astronomical clock 10 to 11 centuries.

Contribution of Syrian Writer:

A Syrian writer named Ridwan Ibn Al Sa’ati composed a book regarding ‘The Construction of Clocks and their use’ in 1203. In Syria, there was a fascinating water-powered clock that struck once every hour close to The Umayyad Mosque in Damascus.

Alarm Clock in Iraq:

A monumental water-powered alarm clock was set in the entrance hall of the Muntansiriya  Madrasha in Baghdad in 1235.

Prominent Alarm Clock in Venice:

Gian Carlo Rainieri assembled the first prominent striking clock tower which bears the similarity of St Mark’s tower in Venice in 1493.

User settable Alarm Clock in Europe:

In the 15th century, a user-settable mechanical clock had been used in Europe which had a ring in the dial clock placing a pin in the hole.

Past Alarm clock in the USA:

Levi Hutchins, a man from Concord, New Hampshire was the first American inventor of an alarm clock who invented it for his job purpose which rang only at 4 am. Later on French inventor Antoine Regier in 1847 patented an adjustable mechanical clock. 

The United States started its production for the purpose of war field in 1942 and later on in 1944 they resumed for daily usage. In the meantime shortcoming of the alarm clock had been developed minimizing previous shortage. Workers were not able to maintain their schedule accordingly amidst the war effort so in a pooling arrangement the office of the price administration allowed to produce new clocks for some companies and some follow the previous pattern and in this way the first postwar consumer goods to be made. 

Classic Bell Alarm Clock:

In a mechanical alarm clock, we get one or two bells that ring by means of a mainspring that gear to move a hammer back and forth. Electromagnetic circuits and armature are set to ring in the alarm clock.

Free from Health hazard:

Traditional alarm clocks are safe from the harm of blue light that affects the brain and body, and EMF radiation that causes cancer according to the International Agency for Research on Cancer (IARC).

Digital Alarm Clock:

Digital Alarm Clock

Now 99% of digital alarm clocks are made using a microcontroller that is more hand-able than the traditional alarm clock. By using it users can easily set or reset their specific time for their everyday lives.

The assistance of electronic drives:

Digital clocks are small in size and not expensive. That’s why it is easy to use with various electronic devices like cars, radios, televisions, microwave ovens, standard ovens, computers, and cell phones.

Radio alarm clock:

James F. Reynolds explored a type of alarm clock to put melodious tunes and news in lieu of irritating sound. Then it had only AM radio stations only. Basically, a radio alarm clock is an integrated device in which an alarm clock and radio are placed together. The clock can play on the radio at the desired time to make the user awake with a beep alarm. Several types of alarm clocks play a double role to wake the incumbent. Typically clock radios are kept beside the stand. A large button is set on the top to make it silent or to resume sounding later.

Clock Radio is more useful for those listeners who prefer to fall asleep while listening to the radio because some clocks have a sleep timer which makes the radio on for a specific amount of time. Nowadays such types of radio clocks are enriched with other music sources such as iPod, iPhone, and audio CD. For ringtone, exoteric songs or radio stations can be set with the true sound of nature like spring, waterfall, rain, etc.

The radio clock is powered by AC power that is why the power supply must be ensured to continue its function. Lack of power supply sometimes miscarries its setting that’s why now some modes have battery service to avoid such problems.

The snooze function in the alarm clock brought a new dimension to this arena that was in 1956. A new dimension came with the invention of the online alarm clock in 2006.
