Hey RJ- Seitz jewels are available from places like Borel's that specialize in watch supplies. Friction jewels are press-fit into a reamed hole much like a clock bushing.

Jewels that are rubbed-in are a loose fit in the hole which is stepped and has a narrow lip edge. This lip edge is rolled, or rubbed, over with a special tool and the jewel is secured in place between the step and rubbed over brass.

I next machine a punch with a pivot about.0005' or.01mm smaller than the jewel diameter. (Having done this over the years I know have punches for standard jewel sizes) Once the pivot has been cut, the square edge on the front is rounded slightly. From this point the tip of the pivot on the punch is pressed into the jewel setting pocket.

The purpose of this punch is to open/raise the rolled edge without removing any metal. The new jewel can now be friction fitted into position. The raised rolled edge can now be pressed back in position very quickly and safely with a flat faced punch. In addition to decreasing any damage to a new jewel, the flat faced punch assures correct final seating position of the jewel. Persoally I do not use the Seitz jeweling tool.

For the most part it has only one practial use, that being jeweling. Again personally, I have found that it is far less practical and versatile than a Staking tool set with a jeweling attachment.
