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.

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.

      Hello from the Philadelphia area

      By Rocco · Posted

      Hello, looking forward to participating on the forum here! I will mostly be listening and asking questions since I am an amateur hobbyist. I have most of the beginner hand tools and a Timegrapher. The extent of my tinkering consists of a successful Seiko 7S26 to NH36 movement swap inside an all original 1997 SKX007, along with a bunch of battery changes for friends and family. I have yet to tackle full disassembly and cleaning. Right now, I don't really have the budget or time to invest in a cleaning setup (even manual cleaning), but hopefully soon! I joined because I recently purchased a mechanical Timex Camper from 1994, and my searches for information regarding servicing and swapping out these Timex mechanical movements consistently led me to Watch Repair Talk. There is also a wealth of knowledge here about dial design, another area of interest for me. My other hobbies includes leather working (mostly small pieces, shoes eventually), crochet, sewing (would love to make clothing), design (especially type design), home espresso, cocktails, and tennis. I want to buy a film camera, but I don't need yet another expensive hobby involving last-century technology. Yes, I have ADHD.
