: I continue on the (very frustrating) mission to unravel the
: purpose / significance of the "Fab. Suisse" marking on
: the dial of Heuer chronographs.

: Please post photos of any "Fab. Suisse" Heuers that you
: have at hand; even better, explain to me why we see this
: marking?

: Laurent: We know the literal meaning of the term "Fab.
: Suisse", but I wonder whether you might have information
: about any relevant French import / labelling requirements?
