I invent tools for myself Ive not seen or improvements to available ones.   These are two different gauges I've come up with.

The pin with the white head has a hairspring collet as a stop. You can measure and transfer the length or depth of the work on a micro scale. It works really well for lengths of arbors while turning.

The other two taper pins are made from sewing needles turned down. You use a permanent marker or ink marker to darken the needle. GENTLY put it into a jewel or a bushing and twist a couple of times. This will make a witness mark you can then pull out and measure the diameter of where it falls on the pin. You can see in the image where the ink was rubbed away at the tips. You would measure the shiny metal right where the ink stops to get your hole diameter. 

Both of these easy to make tools have helped me out many times.

      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 🙂
