The jewels for the train bridge have cap jewels that is screwed on. However, what puzzles me is that the jewels where the wheels for the pivots seems to be upside down, that is the cup were the oil usually resides is on the underside of the bridge. Is this really correct ? How can you control end shake correctly ?

So I was disassembling the Seiko 6349 movement to clean it and oil it and noticed this jewel looks to be in bad shape. I haven't cleaned this bridge yet, but this jewel looks nasty. Could this just be oil residues? Or it's really scratched? By what?

I have been looking for a way to measure the holes in Jewels so I can organize my small collection. I have a JKA tool for the outside diameter but I have no way of measuring the inside diameter of the hole. Correction I have a Swartchild tool for measuring between 0.6mm and 2.0mm but no smaller. I'm guessing I might need 0.01 increments but what are the standard sizes? Am I overthinking it or is there a tool out there made for the purpose. I was looking at a Starrett Pin Gauge set but I'm not sure of the sizes I might require. Any help would be useful. -
