Vintage Rotary Repair. Making a New Winder Stem
Tags: rotary, vintage, watch repairs, winder —
This nice old Rotary was handed in for repair with a broken stem and filthy movement. The problem is with the stem. The movement has no calibre and does not appear in any of our reference books so I have no choice other than to make a new winding stem from scratch.
I do this with blue pivot steel. First annealing the steel to make it easier to turn and cut the thread. Here are some pictures of my work.
