Around 250 BC, An early version of the alarm clock was invented by the Greeks. They built a water clock where the raising waters would both keep time and eventually hit a mechanical bird that triggered an alarming whistle.
The first mechanical alarm clock was invented by Levi Hutchins in 1787. However, the ringing bell alarm on his clock could ring only at 4 am.
On October 24, 1876 a mechanical wind-up alarm clock that could be set for any time was patented (#183,725) by Seth E Thomas.
