Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz movements and digital displays made accurate clocks cheap and ubiquitous after the early 1970s. LED and LCD clocks, clock radios and radio-controlled clocks appeared, while traditional mechanical clockmaking contracted sharply in Germany, France and Britain.

Atlas type guide

Alarm clocks

Alarm work is among the oldest clock functions: monastic clocks woke monks for night prayers, and Renaissance table clocks often carried an alarm disc set by a pin. A separate spring or weight is released at the set time and drives a hammer against a bell. Some early alarms also lit a candle by striking a flint — the 'tinder pistol' alarm.

The cheap, mass-produced alarm clock arrived in the second half of the nineteenth century. American firms such as Seth Thomas and Westclox (the 'Big Ben' of 1910) and German makers such as Junghans and Kienzle made millions of drum-shaped alarms with pin-pallet escapements. Electric, quartz and digital alarm clocks followed in the twentieth century.

What to look for

  • A separate alarm-setting dial or disc and an extra winding key.
  • Twin bells on top (common after c. 1920) or a bell enclosed in the base.
  • Pin-pallet escapements in inexpensive factory alarms.
  • Trademarks and patent dates on dial or back.

Dating clues

  • Renaissance alarm table clocks: sixteenth to seventeenth centuries.
  • Drum alarm clocks: from the 1870s.
  • Luminous dials with radium paint: c. 1910–1960.
