: Is there a chart for dates of production of the
: different models? Thanks

Nope, not really. The Master Table [aka the MOAT] [link below] is the best we've been able to assemble thus far. It is a table assembled from available catalogs and price sheets in the hands of collectors, in table format. We've tried to recreate a picture of the history of Heuer production from these catalogs.

Of course, if you have information to add... Please, let us know!
