Hi Christian,
The "Portraits de Manufacture" book was issued by MJLC and the Musee de l'Elysee in Lausanne.
The book is quite nice indeed (but is obviously not about watches).
I don't know if the Musee de l'Elysee has some? I think you'll have a hard time to get one except through MJLC.
Try with them and please let me know.
Cheers
Dje
