The first mechanical clock, built in the late 13th century, took several years to develop, with exact timelines varying by location and design. Notably, the Salisbury Cathedral clock, constructed around 1386, is one of the earliest known examples, and its creation likely spanned a significant period due to the complexity of the mechanism. Overall, early clock-making involved extensive experimentation and craftsmanship, making precise timeframes difficult to pinpoint.
