Historical context
Early Modern Horology (1600 – 1750)
Huygens' pendulum and balance spring transform accuracy; English makers develop the anchor and deadbeat escapements.
Huygens's pendulum (1656–57) improved clock accuracy from about a quarter of an hour to under a minute a day. The anchor escapement (c. 1670) and the long seconds pendulum created the longcase clock; London makers such as Fromanteel, Knibb, Tompion and Quare led European clockmaking, and French makers created the Boulle pendule.

Atlas type guide
Longcase (tall-case or grandfather) clocks
The longcase clock was born from two seventeenth-century innovations: Christiaan Huygens's pendulum (1656–57) and the anchor escapement (c. 1670). A long seconds pendulum, nearly a metre long, swings with a small arc, and enclosing it together with the driving weights in a tall wooden case protected the mechanism and created a new piece of furniture. London makers such as Ahasuerus Fromanteel, Thomas Tompion and Joseph Knibb set the pattern.
By the eighteenth century longcase clocks were made throughout Britain, the Netherlands, Scandinavia (the Swedish Mora clock), France (the Comtoise from the Franche-Comté), Germany and colonial America. Eight-day movements with two weights became standard in better clocks; thirty-hour clocks with one weight and a rope or chain were cheaper alternatives.
What to look for
- Winding holes in the dial: two (eight-day, going and striking) or none (thirty-hour, pulled up by a chain).
- Brass dials with applied chapter rings (earlier) versus painted iron 'white' dials (after c. 1770 in Britain).
- Moon-phase arches, date apertures, seconds dials and maker's name on the dial.
- Case woods and style: ebonised, walnut marquetry, lacquer, oak or mahogany; regional styles from London, Lancashire, Scotland or America.
- Whether the movement and dial match the case — 'marriages' are common.
Dating clues
- Square brass dials suggest c. 1670–1720; arched brass dials c. 1715–1790.
- Painted (white) dials were made by Birmingham dial-makers from about 1772.
- Comtoise clocks with repoussé pendulums are mostly nineteenth century.
