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

Regulators, wall and Vienna clocks

A regulator is a precision pendulum clock used as a time standard in observatories, workshops and railway offices. Typical features are a deadbeat or Graham escapement, a temperature-compensated pendulum (mercury jar, gridiron or later invar), maintaining power and a regulator dial that separates hours, minutes and seconds. George Graham's deadbeat escapement (c. 1715) and his mercury pendulum, together with Harrison's gridiron, set the pattern for two centuries.

Wall clocks span a much wider range: the elegant Viennese Laterndluhr and Dachluhr of the Biedermeier period, the Dutch stoelklok and staartklok, English 'dial' clocks used in schools, offices and railway stations, and mass-produced spring and weight wall clocks from Germany (Gustav Becker, Junghans, Kienzle) and America.

What to look for

  • Deadbeat escapement and compensated pendulum (gridiron rods, mercury jar or wood rod).
  • A regulator dial with a large central minute hand and separate hour and seconds dials.
  • Vienna regulators: glazed cases, slender pendulum, small weights, enamel two-piece dials.
  • German factory trademarks stamped on the backplate (e.g. Gustav Becker anchor and crown, Junghans star).

Dating clues

  • Graham-type deadbeat regulators: from c. 1720.
  • Viennese Laterndluhr: c. 1800–1850.
  • German factory 'Vienna-style' regulators: c. 1870–1930; Gustav Becker serial numbers allow close dating.
