Watches and clocks
Timekeeping devices are instruments designed to measure and display the passage of time.
The category spans from ancient sundials and hourglasses to modern atomic clocks, with mechanical clocks, watches, and digital displays being the most familiar examples.
The museum's collection of timekeeping devices included everything from pocket watches to ship's chronometers.
Such devices may track hours and minutes, or more precise intervals down to fractions of a second.
