Terry:

I will do some further checking later, but you might want to begin with page 15 of the 1961-62 Catalog, shown on OnTheDash. (A Link to that page is included below.) The 1961-62 catalog is presenting the Reference 1201 (which was the predecessor of the 11204, I believe). The 11204 is shown in the 1963 Catalog, but that catalog does not describe the operation of the chronograph.

The Valjoux 76R was used in the earlier models; the Valjoux 9 in the later ones; I am uncertain when the reference numbers changed.

The 1970-71 Catalog shows the later series(11.401 / 11.402 / 11.404), in which the case was entirely different. That catalog gives brief descriptions of how to operate these chronographs.

I have never seen the instruction shhet or booklet that may have come with these pocket chronographs.

Thanks for the inquiry and please let us know if you find anything interesting.

Jeff
