  1. Can't say for sure.  Once getting it running I needed to regulate it, and it's still running a few seconds/day slow but overall ir works fine.  I have another that needs it's equiv. of a balance wheel and will run until it gets to the same spot on the wheel, thump it and it will restart.  Lather, rinse, repeat... ;)  If I find that part I'll have another.

  2. RLS text not "centered"?  Starts at 37 minutes and ends at 19, pic of GEN attached as example.  Seems this has been an isue with a lot of these over the years.  I checked pics from my long departed Eurotimez V5 and it's off as well.

  3. If you broke off a carbide bit they are extremely brittle and you should be able to hit the inside with a center punch.  Since you have royally buggered up that particular hole you could go ahead and drill all of them bigger, install solid lug bars, and make a MILSUB...  I would say to soak the lug tip in a strong citric acid solution but I don't know if that will eat tungsten/carbide...

    When drilling into existing "divots" you need to drill at the highest speed your equipment can provide or you will likely snap a bit when it breaks through into that "divot."

  4. If the picture you posted is the crown's current state then there is nothing sticking out to grab and unscrew.  Is this the case?  If so you can mix up a citric acid solution and let it sit in it for a couple of weeks and it should dissolve the carbon steel of the stem without harming the stainless.  This is how I remove broken drill bits in case lugs...

  5. I never thought about gluing a dial to a dial but the way I do it is to set the ETA dial spacer on the movement, put a thin bead of JB-Weld around the top of the spacer, and set the dial (sans feet so I guess you could call it a paraplegic dial?) on top, centering it on the hour wheel, and setting a case-back die on it as a weight.  This makes sure the dial is always perfectly centered  on the movement and when I have it lined up perfectly with the stem a little dab of epoxy can be applied to make sure it stays "clocked" if you are so inclined.

    Dial-dots are just too "squishy" and let stuff shift around over time so I rarely use them anymore.  I have tried the Bergeon glue-on dial feet but have not had very good success getting them to stay glued.  Ofter just the slight force applied to the foot when closing the little clamp thingie on the movement is enough to break the epoxy loose.
