Clockmaking is the craft of designing and building clocks and watches. This intricate process involves creating mechanisms that measure time accurately, often using gears, springs, and pendulums. Clockmakers must have a deep understanding of mechanics and precision to ensure that their timepieces function correctly. The history of clockmaking dates back to the 14th century, with significant advancements during the Renaissance period. Notable figures in this field include John Harrison, who invented the marine chronometer, which greatly improved navigation at sea. Today, clockmaking combines traditional techniques with modern technology, resulting in both classic and contemporary timepieces.
