Alpina Bumper Auto Cal 584 Setting Lever Spring Replacement

[hofnerpres]

My workshop record for a watch ' awaiting parts' is five years. A lovely Alpina bumper 584 Auto. Not a common animal and all the setting lever springs 445 seem to have been used up so the usual world searching has proven fruitless. Just about to abandon ship when rescue arrived in the form of Ranfft Mkll. Whoever rescued and improved this site needs a medal.

A post from 7 years ago by Mitka's Vintage Watch service showed the same broken spring on a similar 582 Auto being repaired using a factory part for the Manual Cal 586. This sent me searching the Ranfft pictures and it's clear that the spring  looks common to 582, 584 Autos and 586 ,588 and 589 Manuals. Since I was unable to find any parts information out there this was useful knowledge since a fresh now more general search showed one in Sweden for a 586 at URDELAR.SE . It arrived this morning and it is correct. Buns for tea. Hope this helps - Neil.

I'm sure this will help people but couldn't a spring of been made?

Cousin, Emmy & Borel all show compatible movements although most people would just call the 445 a Set Bridge.

Confused now, are we talking about the spring or the bridge?  Detent and set bridge?

Thanks Andy - I missed the Cousins useful compatible movement listing since they showed the 445 as separate for the different Alpina calibres and this led me down the wrong assumption. I didn't click through since they all showed as discontinued. Lesson learnt. Richard - I wasn't aware this part can also be called a Set Bridge. I'm only 300 watches in and it's still a never ending school day ....

Have you got a copy of BestFit as this is a good reference to what parts are called.

No - so many thanks for that.
