Ingersoll's Clock refers to a line of affordable, mass-produced timepieces created by the Ingersoll brothers, Robert and Charles, in the late 19th century. Known for their innovative designs and reliable mechanisms, these clocks made timekeeping accessible to the general public. The most famous model, the Ingersoll Mickey Mouse watch, debuted in 1933 and became a cultural icon. The Ingersoll clocks were notable for their use of high-quality materials and craftsmanship, which allowed them to compete with more expensive brands. Their success helped popularize wristwatches and contributed to the growth of the American watch industry during that era.
