Vienna Regulators

Partially verified

Austrian and German wall regulators built for accurate domestic timekeeping, with long pendulums and finely finished movements.

Movement & mechanism

  • Weight-driven trains, frequently with deadbeat escapements in better examples
  • Long pendulum with a fine beat adjustment
  • High-quality pivot and jewel work in the best Viennese clocks

Identification

  • Tall glazed case allowing the pendulum to be observed
  • Fine weight and pulley work, often with a maintaining power arrangement
  • Later mass-produced German versions are heavier and less finely finished

Terminology

  • Laterndluhr
  • Dachluhr
  • Deadbeat escapement

Known variations

  • Laterndluhr, Dachluhr and later factory versions

Collecting notes

Originality decides value and interest: check that movement, dial and case belong together, and prefer honest wear over refinishing. Movement work belongs with a clockmaker; cleaning a dial or case yourself commonly destroys the evidence that dates the clock.
