My demagnetiser hasn’t arrived yet, but when it does, let me demag the movement and I will take another picture of the balance spring for some advice. Appreciate everyone’s help. -

Great staking set! I have the exact same and love it. Congratulations on an excellent buy. Is the jewel aligning with the metal? If so, maybe you could. If it's not, there's no way you can control the depth of the jewel with the staking set. I've never used a staking set for jewelling, but I think I've heard others do it. But obviously, a Seitz or Horia jewelling tool should normally be the safer choice. -
Hahaha, never a place where a Monty Python reference don't work, innit? Well, as @JohnR725 wrote and as @mikepilk diagram shows, 9010 is usually considered too thin for centre wheel and maybe also the slower of the train wheels. The issue with that is that it's easier for 9010 to creep away from where it's supposed to be. In my opinion (and lubrication is always contentious), an HP oil (mostly HP 1300, or D5) should be used on the centre wheel. And I usually use thicker oils like 9020, HP1000 or even HP1300 on the 3rd and 2nd wheel as well. But it's contentious. I have a service manual for Rolex 3135 and 2nd/3d wheel are HP1000, whereas a JLC 899 manual prescribes 9010 for those wheels, too. Escape wheel and balance always 9010. Anyway, if we focus on your specific problem of this watch which is rebanking (=too much amplitude): here we can either take a weaker mainspring or use heavier oils (i.e. HP1300) for the train wheels.

As of today I stand corrected - I just picked up my new Boley Staking set 🤩 (from a private seller -> his grandfather was a watchmaker). Do you think it possible to use it instead of a jewelling tool to press out and in the jewel? -
I see that as two different operations. When reattaching the CP using tweezers, there's little risk of damaging the centre wheel arbor, the fourth wheel pivot, or the CP itself. A cannon pinion remover isn't needed for safety reasons, but it is efficient, convenient, and, as a bonus, safe.
