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
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.
