Present day L.U.C. is still very young at merely 15 years, since the Fleurier manufacture was founded in 1996, and as such there is still a lot of history to be made.
I remember a publication by a magazine called Movment which presented a special issue dedicated solely to Chopard L.U.C. a couple of years ago. Perhaps that will be helpful to you as well.
Cheers,
Alex
