hi all I have a Hamilton gr 974 size 16s that needs a new center wheel jewel in the pillar plate. This is my first encounter of this type and so far what I've read is this type of jewel setting is one of the most difficult, if not the most difficult to repair due to its hybrid friction setting. it seems it's a two part setting to include the jewel, set into an either steel or bronze hub, then the beveled edge in peened over to hold the jewel, and then another beveled edge on the opposite side is peened over to affix the entire setting into the pillar plate. Anyone have any experience or advice before I attempt this one? below are the sorry excuses for pictures showing the plates side by side. the one on the left contains the donor jewel, and the one on the right is the missing center jewel. the third and second to the last is the donor jewel and the last is Section 300 out of the book, The Chicago School of Watchmaking that shows a cross sectional view of the procedure. Again, advice needed! i have to do some running but will check back later. apologies on the late wish: to our friends across the pond-my sincerest sympathies on the passing of Her Majesty, Queen Elizabeth. A great, remarkable and very special lady indeed.
