Now this is a broken spring!
Went to wind my desk clock, and SNAP!
No other harm done!

Wow! When that one decided enough was enough, it wasn't kidding!!!!!

Regard! Mark

Glad it wasn't out in the open when it cut loose!!!

multiple simultaneous failure... very interesting. I wonder if it propagates from the center outward like ripples in a pond? I have never seen one do that.

Steven, I've had a similar experience a couple of years ago on this Trenton.

I've had them break while winding before, but not into 17 pieces!
This one was in an Elgin car/travel clock with 2 mainsprings and a very heavy click to contain the backlash, so no other harm was done.
