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.

Water, fire and incense clocks
Before the mechanical clock, intervals and hours were measured by flow and combustion. Outflow and inflow water clocks were used in Egypt, Mesopotamia, Greece, China and the Islamic world; Chinese and Japanese incense clocks burned powdered incense along a maze-like path; oil-lamp clocks with graduated glass reservoirs were popular in German-speaking Europe in the seventeenth and eighteenth centuries.
These timekeepers needed constant correction and could not keep the hour automatically for long periods, but they underpinned temple ritual, legal procedure, astronomy and the earliest monumental astronomical clocks such as Su Song's clock tower (1090s) and al-Jazari's designs (1206).
What to look for
- Graduated vessels or glass reservoirs with hour scales.
- Incense trays with stencils for laying the powder trail.
- Pewter oil-lamp clocks with a glass reservoir marked in Roman numerals.
Dating clues
- Oil-lamp clocks are mostly eighteenth century and often reproduced later.
- Incense clocks were made in China and Japan into the twentieth century.
