: Hello there,

: Can anybody tell me the story behind the Heuers
: made in France? Why did Heuer start making
: the watches here? If France was a great
: place to make watches, why not make existing
: models- from what I can see they designed
: new models to be made in France.

: Are these watches regarded as Real Heuers?
: Don't recall seeing anything in the
: gallery..

: Thanks!
