I picked up a Wyler Dynawind with an ETA caliber 2375.  It has a broken setting lever spring for which I have sourced a replacement.  However, it is also missing a split stem male and female and crown.  Where can I get the right stem?  I am a newbie.  Do I have to make one?

Unless you fancy a challenge it's worth looking at the websites of the usual parts suppliers first. The Resources page you'll find a link to at the head of this forum is a good place to start.

I can see for instance Cousins has both male and female stem parts listed. I'm sure other suppliers closer to your neck of the woods might be able to oblige too.

Also a good tip to a newbie is not to focus exclusively on the movement model you're specifically dealing but be aware of models in the same family. In your case http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&ETA_2375 will list other members of the family. Often you'll find that parts are listed against the first member of the family ... so that's the ETA 2370 in your case. A quick ebay search on 'eta 2370 stem' brings up for instance https://www.ebay.com/itm/ETA-2370-watch-movement-part-404-female-split-stem/132105059577

With these breadcrumbs I'll let you take over...! ?

    • Thanks to everyone for their guidance. Just a quick update. I was able to pull the pipe off with a standard set of handset leavers; the pipe was to small for the presto lever. I then installed the whole Hour Wheel Counter assembly including the bridge. Went together in no time (bad pun). 
    • Wow! Thanks for going all this way to help me! ok, so first I followed Praezis’ advice to correct that red arrow and bring that point closer. I was also wondering if the collet was centered and I tried opening it a little. Thanks Mikepilk for that Chicago lesson document, I’ll keep it at hand in the future! How does the centering seem? Then I used Nevenbekriev’s advice with drawing the bissextiles between the actual and ideal centers. Ended up changing the adjusting the final curve a couple times too…  Here is where I am now : - close when the regulator pins are in « A » position - further away in « R » position Now I know my end curve is not perfectly concentric and that explains the difference, but When I correct it it somewhat makes it worse   Thanks again for the help, love these puzzles somehow 😅
    • Thanks for all the advice! I ordered an ultrasonic machine and 1 liter of Elma red and I'll let you know how it goes.
    • Hello everyone, Hello everyone, Just reassembling this rather lovely movement… my question is this: Can anybody suggest a lubrication protocol for the Auto work on this? I also feel that reassembly of the reduction wheel components will be tricky.. any of you familiar? Also, what is the washer like component?I can’t remember noticing it on disassembly! thanks! tonyG
