Seitz jeweling set

[LittleWatchShop]

Ok, since today was my introduction to "jewel" issues, I decided to open up the two boxes my Dad left to me.  Identical Seitz jeweling sets.  I think between the two, I have a complete set.  What I need help with is the numbering system (measurement system) so that I can organize all of the components into the right slots.

I found a link to a Seitz brochure/manual on this forum.  It is helpful, but does not answer the measurement question.  I have figured out the reamers because they are stamped.

I think those are measured in hundreds of a mm (Metric millimeters).
As an example I can show the 295, I use a micrometer to measure these exactly.

Here we can se the reading 2.5 + 0.45 = 2.95, in hundreds this make 2.95/ 0.01 = 295.
The types you find in the manual so now you can go on sorting them out.

I suspect you'll probably find that the numbers are in metric. Probably has something to do with the fact this is made by a Swiss company. Typically the Swiss like metric.

Shockingly even some American watch factories did, already in 1868

That was the Rosetta stone I needed.  Here...after measuring and sorting, I have almost a complete set.

Hmmm...Ofrei sells many of the pieces for this set

And...I discovered that Bergeon makes two complementary stakes to lantern cannon pinions!  Yes...you guessed it...I had to buy them today from Cousins.

always one of the confusing things in watch repair is isn't just inches or metric there's also some other measurements. Did notice the reference that Elgin is still using inches?

the other place where this really comes up is mainsprings I snipped out some things you can see the Elgin mainspring part numbers the second part of the number is the thickness of the spring in inches. Just because there isn't enough confusion already with mainsprings in metric, Dennison and inches for length Elgin has to have inches for thickness.

Dennison and inches

For a long time, I have been an advocate for using the unit of Smoot for everything. but I have not gotten much traction.

There are few versions of this tool.  From what I've gathered, the oldest ones use Ø3mm pushers, which are hard to find.  Current tools and the pushers that are still made are 4mm.

On the newest ones that cap on the head of the stake is threaded on and can be removed.  A smaller cap is placed on the stake and a solid top piece is threaded into internal threads on the micrometer adjusting barrel.  The handle is removed.  This allows the stake to be pushed down by turning the micrometer barrel.  On the tools without this feature the stake and its cap is a single piece and there are no internal threads on the micrometer.

My set is a little different than pictured.  The "reducing ring" on the right end of the 3rd row is missing and there is no space for it.  I don't know what it's for.

Check the reamers for damage and replace any that show damage, they are not that expensive, only a few pounds each from Cousins.

Check the anvils on these sets. The oldest have 3mm anvils and 4mm pushers, and the newest 4mm anvils and 4mm pushers. Cousins have only 4mm anvils(and pushers.

I discovered that the two tools I have ARE different.  The base that holds the stump are two different size holes.  I measured one to be 4mm and the other is smaller--guessing 3mm.

I received the Bergeon lanterning pusher and stake for cannon pinion lanterning.  Here they are on my Seitz jeweling tool.

More likely to be fixing cannon pinions than jeweling in the near term.

Here is mine. Its missing a few bits and bobs.

I love the wooden box.  Also, yours appears to be made of a ferrous metal whereas mine is aluminum.
