Stem Not Engaging

I took in this "OW" automatic with ETA 2824-2 mechanism. The customer snapped the stem. I was able to get the tiny bit of remaining stem fragment out of the crown with Toe nail clippers. I added a stem extender and began the "trial and error" process of measuring for the correct length. During this process the stem would engage the hands to change the time as well as the date. Now it will only engage the date wheel. Have a knackered something up? I thought I better ask you guys prior to further knackering.

 

Thanks

And to think of the number of times I had to remove the movement from the case, remove the hands,dial, day-disc,date-disc, setting lever to reseat the yoke..... only to have the **BLEEP** thing jump out again!

 

Once I learnt this way of doing things, my fear of the ETAs with the slotted push release dissappeared.

 

The tip to have the stem in the hand-set position before removing is a good one, needless to say, use a screwdriver which fits the slot is important,!

      A lathe with indexing that won't break the bank?

      By coreymsnow · Posted

      Hi folks, I'm doing some homework on getting a watchmaker's lathe, and it's clear I have a lot to learn. But I know one goal: I want to be able to fabricate wheels, which would require an indexing capability. I know how to use large lathes- like, giant metal lathes- but my experience is a few decades old now (but you never forget the smell of the metal cutting oil). So I'm looking to learn anew, and have a goal to get to a point where I can fabricate some basic watch parts. I also have no specific timeframe and want to do this right, so I'll be patient and learn what I need to before spending the money. I know I'm not going to get anything for a pittance, but I'm also not really able to put together the scratch for a $5-$10k lathe. What's out there for a hobbyist that can either handle some fabrication out of the box or can be relatively easily made to do so? Thanks!

      Hello and welcome to the WRT forum.   This usually points to broken balance pivot.  Though a watch in need of clean & lube can do the same. Easiest diag would be to  see if balance pivot doesn't stay in hole jewel of the setting, when you lift one side of balance rim with an oiler or gently with pair of tweezers. Another would be to detach balance complete from the cock and take a look at pivot under high maginfication.  Regs

      Ahhh, yes.  I hadn’t thought of that.  I’ve serviced quite a few of these and the first time I didn’t realise it was a ships strike pattern!  Ha ha, confused me totally until I realised.

      Hi Mike, I did, thanks. Found this clip that was really helpful:   It says Seth Thomas but it's actually the same Hermle I've been working on. I'd had it working correctly all along but hadn't noticed that the lever with the sprung end stops the hammer a bit short of the bell on the second ding at the end of the half-past sequence. If only I'd put the bell on when testing, rather than just looking at the hammer, my ears would have told me it was working,  even if my eyes didn't!
