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.
