Historical context
Early Modern Horology (1600 – 1750)
Huygens' pendulum and balance spring transform accuracy; English makers develop the anchor and deadbeat escapements.
Pocket sundials, Butterfield dials and sandglasses remained essential companions to imperfect clocks; navigators used sandglasses and the log line; observatories began to combine telescopes with pendulum clocks.

Scientific and navigational instruments
Timekeeping has always been tied to astronomy, navigation and measurement. Observatories used transit instruments to determine the exact moment a star crossed the meridian, and set their regulators by it; navigators combined sextant observations with chronometers to find longitude; surveyors, engineers and physicians used counters, pedometers and timers derived from watch and clock technology.
Instruments in this collection show how time measurement supported science and everyday technical life. Their makers were often the same workshops that produced clocks and watches, and their scales and dials document changing units and standards.
What to look for
- Engraved scales and verniers; the units used (degrees, hours, decimal divisions).
- Makers' signatures and town names, often on the main plate or limb.
- Accessories and fitted cases that indicate the intended use.
- Inventory or institutional marks from observatories, navies or schools.
Dating clues
- Vernier scales spread after the seventeenth century; dividing engines after Ramsden (1770s) made fine scales common.
- Mass-produced instruments with patent numbers belong mostly to the nineteenth and twentieth centuries.
