Regulator Clock by Waterbury

I inherited this clock from my uncle. I don't know when it was made, but it was made in the U.S.A. by the Waterbury Clock Company, whom I understand later became Timex.  It measures approximately 33" high by 15.5" wide and 5" deep.  It doesn't work at present, but did work when my uncle had it hanging in his home. Do I pay to have it repaired so it runs again, or chuck it?

Good
