Banneker, at the age of approximately 22, built a striking wooden clock. Legend has it that he based the design on a borrowed pocket watch, meticulously studying its mechanism and recreating it using only hand-carved wooden parts. The clock was remarkably accurate and continued to function for over 50 years.

Banneker's clock quickly became a local sensation. It demonstrated his ingenuity and mechanical skills, bringing him recognition in the surrounding community and beyond. This feat helped dispel prejudices against African Americans regarding intellectual ability.

The wooden clock continued to operate for decades. Its endurance was a powerful testament to Banneker's craftsmanship and mathematical accuracy. The clock was passed on through the family before eventually being destroyed in a housefire.
