Yes Breguet overcoil, and A is OK, the damage is from B to the end. It should look lile this. The studd is fixed by the screw head into the cut. -
I opened up a 17 jeweled Swiss made movement only to find it has a pin pallet escapement. Not sure where the 17 jewels are but they ain’t on the pallet fork! Tips for lubrication?

Hi, This headstock is a little bit too modern for me to know my way round it. The pin that stops the collet spinning is sheared and needs replacing. Does anyone have advice on how to remove the spindle? I’m assuming that you remove the quick change assembly from shaft. Remove pulley. Unscrew front and back bearing plates on the headstock. Then press the spindle out applying pressure to the front (collet end). Has anyone done one of these? Any pictures or links to articles/literature gratefully appreciated. Thanks in advance. Warm Regards Andy

OK, I have 'rectified' the hairspring on the image to show how it should look like. -

This is more complex than a standard pocket watch owing to fact it has 2 driving springs. A mainspring and a smaller spring that acts directly on the escapement. This direct spring provides a more constant torque helping to maintain isochronism and doesn't suffer the energy differences that a mainspring does delivering power through the gear train. The mainspring keeps the escapement driving spring wound up. I have one very similar to this, i wouldn't disassemble it until you are ready to.
