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
Bracket, table and spring-driven clocks
Spring-driven clocks freed timekeeping from the hanging weight. The coiled mainspring, documented from the fifteenth century, made portable table clocks possible; to even out its declining force, makers used the fusee, a conical pulley connected to the barrel by a gut line or chain. Renaissance table clocks from Augsburg and Nuremberg — drum-shaped, square or tower-shaped in gilt brass — were luxury scientific objects, often with astronomical dials and alarms.
After the pendulum, English makers developed the bracket clock: a wooden case with a carrying handle, a short pendulum with a verge escapement, and often repeating work to sound the hours on demand at night. Later examples use the anchor escapement. In the nineteenth century, 'table clock' became a broad term for spring clocks of every nationality.
What to look for
- A fusee in the movement (cone-shaped pulley) and the type of line — gut or chain.
- Verge escapement with a short bob pendulum, often with a decoratively engraved backplate.
- Repeat cords or buttons that make the clock strike again on demand.
- Gilt-brass engraved cases and horizontal dials on Renaissance pieces.
- Case shapes: inverted bell, bell top, break-arch, lancet or balloon.
Dating clues
- Drum and tower table clocks: c. 1520–1650.
- Ebony veneered English bracket clocks with verge escapements: c. 1670–1800.
- Engraved backplates were usual on English clocks until c. 1800, then generally plain.
