An **Alarm watch** is a watch which wakes up a man from sleep at an adjustable time or reminds him of a specific deadline.

===== The first alarm watches =====
Probably the first alarm watch was invented by the Greek philosopher Plato in the 4th century BC by repurposing a [[water clock]] From a container water dribbled permanently into a second container that capsized at a time-dependent filling height and emptied itself into a third container. The air therein was compressed abruptly and escaped through a pipe valve, whose shrill sound clearly could revive the dead.

The invention of the first mechanical alarm clock of the industrial age is attributed to [[Levi Hutchins]] from Concord, New Hampshire (USA). However, his first alarm clock made in [[1787]] could only ring by 4 clock in the morning - this was the time for Hutchins to get up.

The French inventor [[Antoine Redier]] patented in [[1847]] as a first a mechanical alarm clock with adjustable alarm time.

The first chime alarm was introduced by [[Westclox]] in [[1931]]. The alarm clock was advertised with the slogan //"First he whispers, then he shouts"//. [[1949]], [[Westclox]] presented the model "Moonbeam", in which first a lighting turns on and off, and then a buzz is heard.

===== Alarm wristwatches =====
[[Wristwatch]]es with alarm function are e.g. since [[1947]] the alarm wristwatch [[Vulcain|Vulcain Cricket]], since [[1951]] the model "Minivox" of [[Junghans]]. [[Jaeger-LeCoultre]] created [[1950]] the Memovox line and [[1956]] the first [[automatic]] wristalarm.

[[1998]] [[Fortis]] as part of its line of watches presents the [[Fortis Official Cosmonauts Chronograph|Official Cosmonauts Chronograph]], the world's first [[automatic]] [[chronograph]] with integrated mechanical alarm function. This construction was developed by the watch artist [[Gerber, Paul|Paul Gerber]] from Zürich.
