The mechanical alarm clock of the brand Kaiser from the 1930s was a mass-produced article and predominantly used in private households. It is now part of the collection of the LWL-Industrial Museum.
The clockwork was set in motion after being wound up by hand. The clock's alarm mechanism could be preset and awoke the sleeper with loud ringing.
The process of industrialisation with its strictly regulated work hours required people to be absolutely punctual, so they needed a reliable tool to awaken on time.
Domestic alarm clocks became essential for those who needed to get out of bed on schedule. From the end of the 19th century on, they found their way into households as a secondary clock alongside the usual parlour or hall clock.
