Month Duration Vienna Regulator Wall Clock

Partially verified

This antique wall timepiece is a month-duration Vienna regulator dated by the dealer to circa 1850. The glazed case features walnut veneers on the arched crest and base terminal, boxwood stringing across a grained walnut backboard, and ebonised mouldings along the trunk door with carved decorative accents and a pierced top fret. The two-piece enamel dial measures 6 ¼ inches across, displaying Roman numerals, blued steel hands, and a cast pie-crust bezel. Powered by a single brass-cased weight suspended from a spoked wheel, the movement incorporates an 'A' plate design with maintaining power and a dead-beat escapement coupled to an ebonised wood-rod pendulum with a large brass bob.

Open research questions

  • Are there any maker's marks or stamps on the movement plates that can be cross-referenced with Austrian clockmakers of the 19th century?
  • Does the 'A' plate movement contain identifiers that correlate with specific workshops active in Vienna around 1850?
  • Is the pendulum suspension spring a later replacement, given the maintenance history of vintage regulators?
