calendar jumper spring

[adiorio110]

Hi All...

I am back I started  watch repair about a year ago but other projects keep me very busy. Have a little time on my hands so I started tinkering again.

Anyway I was practicing on an old Gruen 518 movement and I lost the  calendar jumper spring. I can't find any parts list or anything to soucre another one. I have enclose a picture .. Maybe some one can point me in the right direction .

 

Thanks

Tony

I think they might also be called shepherds hook. You can buy an assortment of these from CousinsUK if I'm not wrong...

I think that it's a re-branded AS2063 so the part you want would be #2575 which also fits a whole load of other AS20xx movements.

Cousins has them;

It’s a good idea to have a selection of these springs in stock. They tend to fly all over the place if you’re not careful.

Are they quite easy to adjust in geometry or trim in size ? I think i will invest in a random selection too

There quite fiddly to play around with. You have to have the right tension and height.  

Length is easy, just cut off what you don’t need. Making sure the height is correct otherwise the cover plate will cause it not to work.

This is similar to the as2063, but not automatic.

 

 

At 8 mins 30 secs and a bit, mark lifts the balance and cock in one piece. Has the pivot jammed in the jewel?
