Clock Time: a history

Clocks changed how we measure time—and how we live together.

Clock Time: A History is a 32-page graphic history tracing the journey from shadows, stars, and water clocks to mechanical timekeepers, pocket watches, railway schedules, quartz, and atomic clocks.

Along the way, inventions become everyday expectations. Bells gather communities. Watches bring time into people’s pockets. Factories measure working hours. Railways connect towns whose clocks disagree. Eventually, precise timing becomes part of the invisible machinery behind navigation and communications.

A visual story about clocks becoming more accurate, more widespread, and more deeply woven into our days.
