In 1635, the Dutch scientist Christiaan Huygens revolutionized timekeeping with the development of the pendulum clock. Huygens utilized the principle of consistent oscillation of a pendulum to vastly improve clock accuracy, crucially addressing previous timing discrepancies. This innovation not only marked a significant advancement in horology but also facilitated enhanced navigation and global trade by ensuring reliable time measurement, thus playing a pivotal role in the expansion of trade routes and economic transformations.
