Catalogue description

Dealer description — Howard Walwyn

A fine Regency period mahogany fusee dial wall timepiece with wooden dial and with a movement supplied by Thwaites and Reed, London. The five pillar single fusee movement , with tapered plates measuring 7 ¾ inches high by 4 ¾ inches wide at the base, has an anchor escapement regulated by a lenticular bob pendulum. The frontplate is stamped T & R over serial number 5774 . The 12-inch circular integral cream painted Roman numeral wooden dial is inscribed GEO’E YONGE, Strand, LONDON to the centre and has pierced brass hands which are set behind a hinged convex glazed cast brass cavetto moulded bezel applied within slender caddy moulded wooden surround. The box case is secured by pegs incorporating a door to the right hand side and with a pendulum access flap to the curved underside. The rear of the dial panel is inscribed with notes for inscribing the dial for George Yonge dated 1816. Diameter : 14 ¼ in (36 cm) Depth : 7 in (18 cm) * George Yonge is recorded in G.H Baillie’s Watchmakers & Clockmakers of the World as a ‘fine maker’ working in London 1776-1815. Online sources indicate that he worked from 131 Strand, took his son into partnership in 1820 and worked up until 1832. Ainsworth Thwaites was apprenticed in 1735 and worked from Rosoman Row, Clerkenwell, London 1751-80. He was an accomplished maker who supplied the clock for the tower at the Horse Guards Parade. His son, John, was born in 1757 and took over the business presumably on the death of Ainsworth in 1780 before moving to Bowling Green Lane. He entered into partnership with Jeremiah Reed in 1808 and the firm subsequently became well known for supplying all forms of clocks and movements either wholesale for others to retail or signed by themselves. The partnership continued under John Thwaite’s leadership from several addresses in London until his death in 1842. The business has subsequently passed through a series of successors and is still trading today from Rottingdean near Brighton. Ronald E. Rose in his book English DIAL CLOCKS provides data allowing clocks by Thwaites and Reed to be dated from their serial number (Appendix III page 239); from this list the serial number of the movement of the current lot suggests that it was made around 1817.

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.
