A mechanical watch is a timepiece that uses gears, springs, and levers to measure and tell time through physical constants. Invented in the 13th century, the clock relied on a mainspring or weight to store energy, which in turn was released to move the clock gear and hands The clock was accurate by a mechanism they escaped, usually a pendulum, which controlled the movement of the gears. These early clocks, often found in church towers or large public spaces, were a vast improvement over earlier methods of timekeeping such as sundials or water clocks Although mechanical clocks required touch and and can be affected by heat or mechanical failure Mechanical watches hold their own artistic and historical value
