a pin vice is the answer.

Agreed - but if one doesn't own a pin vice? I'm still building up a tool set and it's got a fair few things missing.

I'd start by putting a drop of my lightest oil on the thread and a drop on the stud then leave for a few hours over night is best. This tip comes in hand for anything that is seized up. Be careful that hair spring looks o k . I would place the whole thing on the bench cock down and prize the wheel and staff out of the collet start with a couple of razor blades then two fine screwdrivers. Or two thin knife blades put the wheel and staff in a safe place if the hairspring is tapper pinned in the stud the balance and H/spring can be separated from the cock here and not at the collet/staff . The stud grip screw look big enough for a couple of flats to be filed on it for extra grip.

Get yourself a set of eclipse pin vices they are by far the best. Last a lifetime. It is a tool that you will always need, there very good for holding watch stems.


I agree. It’s horses for courses and you need a pin vice. Otherwise high chance of creating damage. That will cause a whole lot of hurt to repair!

I like the pin vice idea; however, the escape wheel looks to be quite close to the screw... Perhaps pull the bridge and allow the escape wheel to drop out of your way before you go at it with the hammers and torches. Doing it as-shown, with the bridge in place might cause other problems for you.

Just my two cents.

If you mean the balance wheel I agree.

Yes, balance, not the escape wheel.

Yes! Well spotted. The clearance is quite tight. Perhaps raise the cock to give better access. I would still try pin vice or x-acto tool first. The x-acto tightens like a mini Jacobs chuck, (threaded) and will give a good grip.

      Unfortunately I'm not that lucky. I started on the train side and after I noticed the binding I pulled everything out except the driving wheel to rule everything else out. It still binds. I'm going to double check that the pinion is fully seated on the staff first, then if no joy I'll push the bridge jewel up a fraction of a mm. Fingers crossed!

      Thank you for the advise!! It worked. The setting screw was a lock/unlock to remove the rotor.

      I have that French tech sheet too, it is a little different than the English one (eg, it doesn't have the auto works diagram). BTW, it looks like you are looking up the case number in the 1979 ABC supplement. The 1974 ABC catalog does have the 3093 case. As you determined it takes the 1222-5 crystal.  When I serviced my President 'A' (which also takes that crystal), I was able to fit a 29.8 crystal from my DPA crystal assortment. Those are, in my opinion, a great deal. The assortment comes with 10 sizes each from 27.8mm to 32.4mm in 0.2 increments. I pretty much use them for any non-armored crystal that takes a high dome crystal. I think they no longer make them but Cousins has still has some in stock but when I bought them they were around $40 for the set and now they are around $100. Still, at 40 cents a crystal it's still a good deal. For the large driving wheel, I remember I once assembled the keyless/motion works first and when I placed the large driving wheel it was interfering with the setting wheel on the dial side as the teeth were not fully meshing and it wouldn't fully seat. If that isn't the issue I got nothing and am looking forward to see how you solve it 🙂

      Not sure, but just looking at it, it seems like the screw on the right may be a fake? The one on the left may not be a screw in the regular sense at all, rather a 2 position device, I think you need to point the slot towards either of the 2 dots and one will secure and one will open. Like I said this is just my best guess looking at the pictures.
