hi guys, could anyone help me with the correct staff i need, this is the biggest hurdle for me so far, identifying staffs ,
waltham, 16s, 17jewel, estimated year 1908, model 1908, grade 625, breguet balance spring, micrometer regulator
so far im led to friction fit staff, but this is definatley not.
i wondered if waltham had a book listing grades and model numbers?
appreciate your input and knowledge on this subject
cheers all
