Here is a chronograph (currently listed on ebay) assembled from parts of three different Heuers, representing the best of the 1950's, 60's and 70's.

-- The dial and chronograph needles appear to be from an older Heuer, reference 2444, from the 1950's
-- The case and larger hands (time of day) are from the manual version of the Carrera, reference 2447, from the 1960's
-- The pushers are from the automatic version of the Carrera, reference 1153, from the 1970's

It is a shame that these "Franken-Heuers" seem to be coming onto the market with such frequency; perhaps this is the price of success -- as the values have increased, the urge to manufacture and sell these "fakes" also increases.

Let the buyer beware . . . and prospective buyers should also keep an eye on this Discussion Forum and post photos of anything that looks suspicious.
