hairspring studs for Rolex

[rumjungl]

Hello,  I have a NOS balance complete for a Rolex 1560 movement.  They apparently are packaged without a stud attached to the hairspring.  Is there anywhere to source a proper stud for this?  Thank you.

You can get a selection (Round or Square) from Cousins we need a pic to give better advise.

Sure it's NOS . Sounds kind of strange that it doesn't have a stud.

Hm, as far as I know the spare part balance ist complete with stud. The part-nr. for caliber 1560 is 7980. Looks like this:

The stud is special, it has a triangle shape, which insures correct positioning in the stud holder. I don't know whether it is possible to purchase a single one. I've never seen one on the bay or elsewhere.

Hopefully it is not a triangle as they can not be found anywhere. If I remember correctly many Seiko studs a this shape & I could not find one and in the end re-shaped a square stud and it was a pain to say the least.

Maybe it's been broken of at some point?

They normally have the stud attached, if it doesn't have it, it's either been broken off and won't time properly, or was missed at the factory.. send it back?

Unfortunately, I purchased this a couple years ago for a project I just started, so returning it is not an option.  Here are a couple photos:

Ah, ok.. thats really old packaging (70's-80's) so it may have been supplied like that back then..

On an upside, it should be close to right for pinning at the end, and there is a fair amount of adjustment on the meantime +microstella screws to get it the rest of the way..

Looks like the square ones from Cousins are the only option.  I can't find any damaged 1560 balances to use a donor at the moment.
