The cal. 67 Ébauche (puzzle) project. (Part 1 of x)

I have this old cal. 67 Ébauche, including many authenic parts (perhaps all) of the movement, since some years, but I was to lazy yet to check, if all items are complete.

My idea is to mount a running movement, because it makes no sence to keep those items unused.

And an 67 Ébauche based movement will be unique.

Cal. 67 has been developed and produced (aprox. 2500 pieces) in the mid 30s.

A robust - and pricise movement for civ. - and military watches.

Many current IWC movements are not finished any more, so my Ébauche is state of the art, if I am able to put those puzzle of parts together :-)

But this is a long term project and I will use this opportunity to make high quality macro photos of many movements parts.

For me, it is like a time shift to notice those hand written wrappings with manufacture items inside.

I am not sure, if this consuming separation of parts was usual at production or has been done later by a careful watchmaker ?

Any information about it would be interesting to me.

This first post about this topic shows the uncleaned Ébauche and the wrapped parts with handwritten information on the content and the separate wrappings inside of one tiny box.

More details will follow.

I have planned to continue this post time by time depending on progress, with a lot of macro photos.

But you have the opportunity to stop it, if this uncommon stuff gets too boring, plaese let me know, thanks.

Dear HEBE

Very interesting Packing of a movement.
Somewhere in my bags, I should also have an Ebauche of a c.67,
Bu I think I just got the Ebauch, mot all the aditional parts.
Is it posible you "packed" complete movement is from a watch makers scool, when a student got this pack, to build a watch during his last "Year" of work with the task to finalize and assemble it?

regards

Ralph

P.S. I think the number should be approx. 25'000 pieces....

That is indeed an interesting hint, thanks Ralph.

Unfortunatly I have no background history information about this set.

But the effort for packing those items for a "normal" production makes really no sence.

That's quite obviously a set for an apprentice, who had to make "his" watch from a kit. Maybe some parts are missing: Those parts the apprentice was asked to produce on his own as part of his exam.

The ebauche should have nomovement No. respectively a three digit school No. As the completion of the movement appears not to have been started I'm quite sure the School No. hasn't yet been applied.

The Cal. 67 was quite often used for School watches from the 1930ies up to the 1970ies. I have about eight in the bank vault from different schools and with different tasks the apprentice had to cope with.

Another importent expert hint, thanks Thomas.

So, this set is getting more transparent and the packing effort makes sence for a school watch movement.

I think, not many other forums offer the opportunity for an analysis of this strange set.

Very true; the extraordinary and unusual information that is brought to light by various members of this forum never ceases to amaze me.
