Historical context

Golden Age of Mechanical Watchmaking (1900 – 1945)

The wristwatch displaces the pocket watch; waterproof cases, self-winding and grand complications.

Between 1900 and 1945 clocks were electrified: master-clock systems ran factories and offices, synchronous mains clocks entered homes, and the Shortt free-pendulum clock set new standards of accuracy before the first quartz clocks (1927). Art Deco design reshaped mantel and table clocks.

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.
