I just got this little time only Junghans in with a broken main. Just for thought, If a spring close to the arbor, is it likely to do less damage than if it breaks on the other end?

Ok, to the question, I'm ordering a new spring. the original one measures 12 mm wide x 0.38 thick x 40 1/4" long. The closest match at timesavers is made for a Hermle barrel #32 and it measures 12 mm x 0.42 x 43.3" Is that a good match? It's just a touch longer and thicker.

I know there's a calculator for that but I can't seem to find it.

Thanks, Danny
