Clock Mainsprings

Restore the Heartbeat of Your Timepiece: Premium Longcase Mainsprings

There is nothing quite like the steady, rhythmic pulse of a grandfather clock. But when that rhythm falters—or the winding arbor suddenly spins freely—it’s usually a sign that the mainspring, the very engine of your clock, has reached its limit.

Our collection of replacement clock mainsprings include barrel type, loop end, ansonia rivet end and 400 day mainsprings.
