Hi Suitbert,
Happy to read you here!
I fully agree with your opinion. Things are certainly not simple and yes it is quite probably not just "invented" by JLC.
Then JLC is a watchmaking company, producing only in-house calibres.......... so communication must be I guess!
But you know the watchmaking world (like me to some extent only).
If I say you that I happened to visit the "Specialites Horlogeres" department, i.e. the complications department, last year and they were assembling a calibre that they don't produce and don't sell! This world is so intricated!
Cheers
