Thank you, Francisco for yet another great review!
In reading the reviews for the modified 7750's (daytona, portuguese, and this one), the addition of one or two (at vital gears) would make vast improvements. Given this, how challenging/difficult would it be to add a jewel to this movement? Certainly, I understand that the right tools would be necessary, but given the talent we have here, is it something that can be "reasonably" done?
I must admit I'm just a novice at these things; however, after seeing some of the mods that are done here, certainly adding a jewel is possible...?
