Hi all.
I'm servicing a EAT 2824-2 movement I bought of an auction website. There was no stem and I took a gamble.
While waiting for it to arrive I ordered a new generic stem, and assumed it should fit.
Taking the keyless works apart, I could see the remains of the original stem still in situ.
Comparing the original to the replacement, they are different across the flats. The original is 0.51mm. The replacement is 0.74mm and will not fit the sliding and winding pinion.
Does anyone know where I can source an original with 0.51mm across the flats?
