In August of 1905, The Elgin National Watch Factory completed the 144 foot clock tower, which would serve as their symbol of elegance and dignity for many years.  The Seth Thomas Clock that resided in their clock tower had a gravity escapement and was regulated by a pendulum that was fourteen feet long.  The weights on the bottom of the pendulum weighed 330 pounds.  

This clock was the first self-winding clock to ever be put into operation.  The four dials on the clock were 14 1/2 feet in diameter and the minute hands were more than seven feet long.  The clock could be easily be read at night even at distances of a half a mile away.
