In 1654, Dutch scientist Christiaan Huygens invented the pendulum clock, marking a pivotal advancement in timekeeping. This innovation offered a more consistent and accurate means of measuring time, revolutionizing maritime navigation. With improved precision in determining longitudinal position at sea, the pendulum clock enhanced trade routes and maritime exploration. It facilitated reliable schedules and coordination, impacting global interactions and commerce. Huygens' work significantly influenced technological progress in horology.
