I purchased a replacement pendulum clock movement which was shipped and correctly fit the clock face. But
The clock didn't hang correctly because wall hang mount ( which cost extra) was designed poorly. As designed the pendulum would not move because it was pinned to the wall by the clock mechanism/ hanger.
After a couple of phone calls to tech support the solution was for buyer to shim the clock mechanism so that the bottom of the clock mechanism was same thickness as the overly thick wall hanger.
Really... that's the solution? All sales final so...
Suggest buyers choose a different vendor.
