I would tend to agree with you if JLC made some easy money with the release of such watches, exclusively, but you said it and you're right, it is not the case.
Vintage is popular because of ITs own qualities, I guess, which are a story, soul, and an undisputable charm.
Now, we also have to say that a big part of the modern JLC production is strongly linked to the Past.
Have a look at the watch in the real, and then please share your feelings with us!
Best,
Nicolas.
