Catalogue description
Dealer description — Howard Walwyn
A fine George III period mahogany regulator of small size. The refined case with a shallow moulded cornice, similar to the case work of Thomas Mudge, is veneered with mahogany of fine colour and patination. Standing on block feet, there is a double plinth to the moulded panelled base. The trunk door has a shallow arch top which is repeated on the hood. The latter has brass inlaid fluted canted corners to the front. The 10 inch brass dial is signed at the top Aubert and Klaftenberger, London . It has an Arabic minute dial which encloses two subsidiaries, an Arabic seconds dial and a Roman numeral dial for the hours. The substantial 8-day latched movement is of the highest quality, with five knopped pillars, a deadbeat escapement and maintaining power. The wooden rod pendulum has a heavy lenticular brass bob and outsize brass ball shaped rating nut. Date: circa 1785 Height: 74 ½ in (189.25 cm) Width : 16 ½ in (42 cm) Depth : 9 ½ in (24 cm) * It is probable that this fine regulator was never signed by its original maker but was inscribed and sold by Aubert and Klaftenberger in the 1840s when they were making and retailing clocks in London.

Historical context
Precision & Scientific Horology (1750 – 1850)
Harrison solves longitude; Mudge invents the lever; Breguet's Paris workshop defines the modern watch.
The age of the deadbeat escapement, compensated pendulums and observatory regulators. Domestic clocks spread through the middle classes: English longcase and bracket clocks, French gilt-bronze mantel clocks, Viennese Biedermeier wall clocks, Black Forest painted-shield clocks, and the first American shelf 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.
