Jeff,

Thanks for the useful start. I'm in the process of searching for some Cal. 9 parts to get the stop watch feature going again. I can see that it's a later version of Ref. 1201 and the operating instructions would be the same I imagine.

: 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
