Case is legit. Bezel is legit. Case back is legit. FE4611A w/Heuer etch is suspect to me (early Monnin's had either no etch or G. Monnin etch on the rotor). Some may disagree with me on this point. Dial is probably "Made in France" version based on spelling of "professionel" with an e vs. a. I'd say selling as a "custom" piece between $500 - $1000 based on what a seller would pay would be a correct range for what it is. Again, its a nice looking piece, and given many are custom, someone can enjoy it for what it is.
