Yes, this is a 7 jewel watch movement. There is a hole jewel and capstone at each end of the balance staff, which is 4 jewels. There is the roller jewel in the roller table on the balance staff, bringing us to 5 jewels in total. Finally there are two pallet jewels in the pallet fork, that lock and unlock the escape wheel and help to provide impulse to the balance wheel, bringing us to a total of 7 jewels in the watch.

Excellent suggestion on rep pivoting the older staff this should be possible

@@JDRichard It’s definitely possible and if you snap a drill bit off, turning a new staff remains as an alternative. I find some antique Omega staffs are unusually soft compared to most staffs of that era. This often evidenced by a really big bend in a pivot, a bend so severe that it would’ve snapped the pivot off if the staff was fully hardened. If this staff is one of these softer ones, they’re comparatively easy to drill for repivoting. Whilst I normally consider shimming balance cocks and other such means of adjusting balance endshake a last resort, on lower grade work like this it’s a more acceptable way of saving time whilst still getting a good end result. There’s a trick to fine tuning the staff endshake after repivoting that entails leaving the staff slightly tight once mounted and setting the end shake as you screw down the balance cock. If you don’t know this technique, let me know and I’ll shoot you an email to explain it. It needs a couple of images so I can’t explain it here.

@mercuriall2810 You got me curious.!!

@@mercuriall2810 yeah I think I’m gonna re-pivot all the new pocket watches that I have to repair in the future as opposed to making Brand new balance staff

@@JDRichard I’ll shoot you an email later today explaining it.
