All Willard Brothers were born at their modest family farm in Grafton, Massachusetts, successively between 1743 and 1755.
Owning independent workshops at Boston, they were the most celebrated clockmakers in the early United States.
After his last son was born, Benjamin Senior apprenticed in horology craftsmanship, and subsequently he opened a workshop at the farm.
Initially, Simon Willard's main economical support stemmed from the Tall Clock production but he didn't produce these models longer after 1802 when he patented his Banjo clock and this invention became Simon's main sustenance.
Tough, Simon Willard preferred rather to build special great clock models which have had historical significance indeed, whether in galleries, churches, and the like.
This modern compact wall model was widely copied by competing clock manufacturers although for him Willard didn't claim the royalties which should have rightfully corresponded ever.
These clocks kept the original Simon's frontal glass style and with their brass mechanism they ran for eight days.
