Question

Cheers Mates!!

Im doing service on a Alpina 582, and the main spring slips over in the barrel.

I have bought new main spring, but it stills slips over inside the barrel.

Can somebody tells me how  the original main spring looks alike??

I had to buy on from CousinsUK, but I would like to see how the original spring was sat togheter insiden barrel.

The spring was missing so I only have the barrel...

This movement is a bumper automatic. The main spring is supposed to slip, some are attached to a break spring, the break spring should slip with the mainspring.  Old autos are sometimes fitted with an extra short piece of spring which is much stronger than the normal spring that fits inside the barrel, that acts as a break, the normal auto spring is attached to that. You shouldn’t be able to wind up an automatic. Here is a photo of a modern auto mainspring.

If that is the case, you don't have the correct spring. I would ask for an auto mainspring and try that first. The barrel is most likely obsolete. 

Yes, that is right, I have orderd wrong spring, thats it.....  thanks oldhippy!!!

Had not asked if I could wind it six times, and the spring slips....

This slips on the first turn, of course....

 

If that is the case. Then take a good look at the inside of the barrel and check for wear. You should be able to wind it many many times before you hear or feel the spring slipping.

Okay, then I understand a lot more:

1. The spring I got from cousins have not with the extra part, like on the photo.

2. The inside the barrel is pretty woren, lots of strips inside.

Suggestions what todo?

Find new spring?

Perhaps the inner coil is too large and it's not hooking on the arbor, or it's in backwards. A photo of the barrel with cap off will help.

Nope, I always check with a plier to see if the arbor is hooking up....

Bridle is missing or dosn,t look like it had one to begin witn. Manual wind springs lack large bridles. 

There is also the possibility of this having come with two pieces mainsprings like Mido 816.

Strips on the barrel wall work to your advantage, keeps the bidle from slipping too easy. Strips on the bottom of the barrel should be flattened with sandpaper.

I took some minutes to look at what spring might fit in your barrel. Looks like the 582 has the same spring as the 584 and then you according to BestFit can use the same spring as the ETA 2820 . 
As a curiousity the same spring is also used  in:

ALPINA 584
ETA 2820
ETA 2820R
ETA 2822R
ETA 2823
ETA 2823R
ETA 2828
ETA 2828R
ETA 2829
ETA 2829R
ETA 2834
ETA 2834R

Maybe this information can get you into the right track..

When the spring is fully wound the auto system will still try to wind and something will break. The slipping spring is essentially a clutch, the braking grease makes sure it doesn't slip too much.

 

 

 

    the same can be said for ancord main spring.  just know how to wind it.   have you heard of a "lifetime main spring"?  to each his own,  cheers.   vin

Well the automatic system only know to wind, not to stop when it feels too much resistance.

You cannot wind an auto fully up.

  yes it's a clutch,   when it wears down you can still wind it some.   originally patented by Movoto.  how can you tell which watches "have the clutch".   vin

      Working on a Tudor Oyster Prince with ref no: 2081/4     with a ETA 2784 movment.
      Cleaned and inspected, all looks good, no sign of wear and tear on the main spring, no sharps bend, looks overall good. Noticed that there where some marks on the barrel wall. But that I have seen before witout any drama....
      Oiled it , put togeher , goes like a dream..... but the the spring does not stick, it snaps over after 6,5 turns by crown.
      So the question is:
      Can I just replace the main spring?
      Can I just replace the main spring and do something with the barrel walls ?
      Buy a new barrel with spring? Is it to be sourced?
       
       
       
      Ref 9081/4 is the ETA 2784

      Hello,
      I had a lot of fun rebuilding my first pocket watch, a 'Goliath' (see pic).
      After 2 weeks of working well, the mainspring snapped...
      I brought a new mainspring from Cousins; I would not find an exact match of the original.
      The original measured: 3.10 x 0.20 x 620 (mm) Cousins replacement: 3.00 x 0.23 x 640 (mm) Could the differences in specification have caused the breakage?
      Or was perhaps the spring faulty?

      Hi All,
      I’m a Lemania collector and as a hobby I try to service some watches myself. I still have a lot to learn and currently i’m a bit stuck with finding a decent main spring for a Lemania cal 3600 (automatic).
      Here’s my problem:
      I ended up with 2 different specifications for a Lemania 3600 mainspring based on the following pictures (see attach).
      Maybe the Marco one is less reliable because it has a hand written specification instead of a printed one….?
      Now, there is a wide variety of auto mainsprings available here: http://www.ofrei.com/page_112.html and here: https://www.cousinsuk.com/category/mainsprings-by-size-watch-pocket
      The thing is that  they all differ on at least one of the specs. I can imagine that the width is crucial, otherwise it will just not fit, but other things like length, is some margin allowed there? For example instead of 12,5 inch is 12 or 13 inch also ok? If i have to choose, which specifications are more important, for example strength is more important then length,..…?
      Would be nice if somebody could give a good hint to a mainspring to would fit in a cal 3600 .…
      Thanks!
      Gert
