I took several pictures to prepare one or two topics about them.
It just takes time, and if I have a moment, will try to take other pics of the Q.L only.
There is indeed a lot to say about these Duos!
Thanks for your nice words, Christian.

Something tells me that you won't disagree with me...
Once you tasted the " dark side ", it is difficult to come back.
Best, my friend.
Coffee?

There's no shortage of movement decoration here, and these 2 pieces (I am told a particular expert) exceed ANYTHING PP or Lange have out....but you would know better Nicolas.
It's these pieces that I hope JLC will keep as slow-release, continually advertised, brand-building pieces - on the high side, and the EWC - for mid-level, and Reversos - on the lower level.
With the correct, continuous, targeted marketing, JLC could soon be accepted for its TRUE value by the watch-loving public at large (just ask Jean-Claude Biver).

About the Duometre, I was told ( in October 2009 ) that there were a few hundreds made ( à chronographe ), and my guess is that JLC wants to see this Duometre lasting quite a long time.
I don't see why it would be different for the Q.L which is a more " intellectual piece " than the Chronographe.
My dream is to see some " Entry level " belle horlogerie " at JLC.
For the moment, we are happy to see the Cal 849 ( Master U.T 
and the Cal 822 ( basic Reversos ) existing.
Nice movement, with an interesting level of decoration and finish for its category price.
I would love to see some more manual movements, with a superior degree of finish and decoration, not ala Dufour or Voutilainen, but well, you got my idea, ala Geophysic, let's say.
As for the Duometre, can't agree more with your opinion, I sing its virtues since April 2007, and totally convinced and fan since the very beginning.
I don't see why JLC would be seen as inferior to PP or Lange with the Duometre, personally, except the fact that there is No PP name on the dial, which is pretty good as the Duometre attracts true passionate of fine horology, not snobs.
Could JLC be soon accepted for its true value?
Here is my personal opinion: JLC has already earned a lot of- more and more- sympathy, these last years, and starts to reach this " recognition " value, with such enthusiastic masterpeices such as the Duometres, the Gyro I or II, the MMRs, and so on.
The Tribute To ... is also a good way to pay homage to the rich patrimony of the brand, and should prove, demonstrate to all what JLC was able to do in terms of Innovation, at this time ( even if the competition was serious, but if you take all the watches they made in from the 30ies to the early 70ies, what other brand can say the same? ).
I think JLC is in the good path, sincerely.
Best, Dean.

Knowing that some Beauties exist, in this world, is already a feast.
Well, it is better if you can get it, true.
Pleasure is not a question of money: I can't afford an Aston, but each time I see one in the street, it makes my day.
As for the Vintage, yes, there are some great alternatives, my friend.
Best,
Nicolas.
and still my favorite of the two. Perhaps evnof the the line. And agree the moon phase is a improved on this one.I have to replace my Duometre à Chronographe in platinum, which is part of the watches which have gone, sadly...
The Black sister could be a great alternative, for sure.
Unless I go on the Q.L, or even better, on both.
Don't really know which one is my favourite, I don't know if I can even say that one has to be my favourite, though.
They are so close and so different at the same time.
Hmm, if only we could have this kind of dilemma, and only this kind of dilemma, in Life, it would be delicious dream, unless it is a Reality, or a fantasy...
Best, my friend.
Nicolas.
Will do it as soon as I have the time to work on them.
Best,
Nicolas.
Absolutely awesome picture of two stunning black beauties.
Interesting to note that the Chronographe is still available. The tough part is choosing one over another.
Wonderful executed but one thing that bugs me is the plate 'No xxx/200' on the dial side.
I am looking forward to more pics and text from you about these two Nicolas.
Best,

Rather than the LE number, which I don't care at all, or, better said, I would have preferred seeing that these 2 black are limited in production than in Edition.
But, for once, it is not a too high LE, which is a good thing.
Best, and thanks for your encouragements.
Nicolas.
There are truly some very interesting things on these 2 black Beauties.
I'm often deceived by the moonphases, but here, I'm fascinated by its design, its feeling.
Best,
Nicolas.
My absolute favourite line among all the JLC families of products.
There is such an interesting homogeneity on these watches!
Thanks, Rahul.
Best.
Nicolas;

JLC, when they released the Duometre, in 2007, clearly stated that there will not be a Duometre in any other metal than a precious one.
The Perpetual Calendar you're speakingf about doesn'tg have the same level if finish and decoration, it is targetted in another league than the one the Duometre is playing in.
The good news is that JLC will play with the Duometre, and introduce, regularly, some new complications.
When will we see a new Duometre? Probably in one year or two.
What could it be? No idea, but I'm damn excited.
Best,
Nicolas.
Seems I'm engaged on the long version.
Best and thanks for the nice comment;
Nicolas.
