Waterbury triple plate westminster chime mechanism: mainspring specs:
Time mainspring: .018in. X .750in. X 96in.
Strike mainspring: .014in. X .750in. X 96in.
Chime mainspring: .0225in. X .874in. X 78in.
At this time there is no replacement available for the chime mainspring; it must be
custom made.
