Hi, all pictures show parts directly after milling, first picture is the crown wheel, second picture show some hairspring stud plates, third picture the ratched wheel and the fourth picture the balance wheel bridge. All of them are cutted directly into a bar of AP20 steel using some delicate endmill down to 0.25mm.
After milling they have to be turned on the lathe to the right height after that they will be tempered and finished by hand this will be take a few hours up to days per each part.
