Hi all,
Just an uniformed collect, don't repair novice still. Actually I have neither the patience, knowledge, nor steadiness to repair.
What really does overbanked or overwound mean ?
Are these major dilemas with a watch ?
Thanks,
Bill
Actually as i am typing this I have a Columbus transitional watch either key or stem wind, that I was just admiring, and I went to stem wind it, and I heard what sounded like a spring releasing, and now it isn't working, any ideas,
Thanks

Hello Bill, it sounds as though the main gave out you....I wouldn't do anything with the watch just yet, unless you have already....

I'm not a watchmaker but I'm sure one will be by shortly and can advise you of what to do next....

Good Luck,
Regards,
Jerry

Hello - Over banked is a legitimate condition which very simply stated implies the balance is out of joint or the roller jewel is not in the proper location. Over wound is an euphemism for "It ain't working and I don't know why.".

Bill,
'Overwound' is generally the 'euphemism' for a watch which is fully wound tight and not running.

Usually, it means the mainspring is coiled dead tight in the barrel and 'Set', it has no grunt left to drive the train.
If you pull such a spring out of the barrel, it will remain fairly closely coiled up.

Overbanked, is when the roller jewel, instead of being able to move through, and be impulsed by the horns of the lever fork, gets on the wrong side of the fork because something (shock from a drop or mainspring breakage) has forced the guard pin on the fork past the roller table, which then causes the lever to be jammed against a banking pin and locked. (overbanked).
This happens when the balance has been 'impulsed' and the roller has travelled out of and past the fork.

When the balance swings back again, the roller hits the back of the fork and stops.

Sometimes other issues such as stripped or bent train wheel teeth, displaced/broken pallet stones and broken pivots can result from a fair old whack from a mainspring breaking.
So they 'Could' certainly be major dilemas!

It means send it to Chris Abell, especially if you heard that little "zzzzZZZIPPP-SPOINCK" sound when you wound it!

Quote: "zzzzZZZIPPP-SPOINCK"

Hey Dave, is that anything like Goober on Andy Griffith when he would say, when diagnosing an engine noise, is it "ka chug, ka chug", or is it "ka chang, ka chang"....

Well All,
Thanks for all the infor rwgarding overbanked , and overwound, and Dave remarkable the noise heard was just like you said zzzzZZZIPPP-SPOINK, what a great imitation of the noise. I know of no other that can impersonate a watch noise, so well.
(joking) although a good imitation.
Thanks,
Bill
