Weakened Incabloc spring.

Hi all,

Is  it possible that if you have to release and secure an Incabloc jewel a few times, that can weaken the lyre spring? I have a lower one on a ladies movement that is now reluctant to expand into the slots in the block. I am replacing it anyway. It is the lower one so it is smaller than the one on the balance cock.

Regards.

Hi fj,

generally no. If the spring is manipulated just enough to clear the lip it should not affect its shape. It could be someone forced it to far and bent it back to its proper shape. Once this is done it will break eventually.

It quite easy to damage these springs on ladies movement as the gap at the 'waist' is very tiny and you only need a microscopic amount of movement.

Personally I think the kif ones are worse
