Jaeger-LeCoultre

Yes, Goldenlutin, I still have to see the watch in the real.

I couldn't, when I was at the Manufactire, in December. But don't worry, you will have lics pictures of it, soon.

No, for me, the Tourbillon is not exo, it wouldn't be possible in  such a flat Watch.

The movement is 4, 8 mm high.

I've just shared sme first impressions, be sure that the Watch will be autopsied later. wink

Best, and happy to see you on the JLC forum, too!

As for the movement, Goldenlutin...

That is maybe why they installed the rotor BEHIND the dial, to gain some precious and extra " dixièmes de millimetres "?

About the peripheral automatic winding system...

 
 By: Goldenlutin : January 11th, 2014-00:53
Hello  Nicolas,

Thanks for your answer. Basically the interesting/useful thing about a peripheral automatic winding system is that it can be set around the movement, adding virtually no hight to the movement (like the last ultra-thin Breguet tourbillon shows). As it is around the movement, the downside is that it increases the diameter, what you can see in the 33mm diameter here (unthinkable 15 years ago). AP also uses a similar system to make its RO automatic tourbillon chronograph (I am not talking here about all the movements with peripheral rotor but only the ones totally around the exterior of the movement) . Regarding the fact that it is visible dial side, I think is was a purely aesthetic decision but I might be wrong. AP's one is totally hidden by the case/dial for instance, making the automatic winding "magic".

Still, the most intriguing thing IMHO is really the flying balance.  This seems technically almost impossible (due to shock protection [where is the upper Incabloc?, there must be none], fixing the hairspring, frictions, resistance to lateral shocks, etc.). It will be very spectacular in any case but hopefully also reliable. You could have achieved something visually similar using a sapphire top bridges. 

Best,

Goldenlutin

THe flying balance is something which intrigued me a lot, too.

I will ask JLC how it can be compatible with shock protection.

I had a long conversation with JLC yesterday, but there were so many questions to ask about this watch that we agreed to have another discussion in Geneva, soon.

I have the feeling we'll have fun,  and a lot of passionate discussions!

Best,

Nicolas

Nothing more to add dear Dr. Hanke

The open slots in the dial are primarily cosmetic...

To show the peripheral winding rotor in motion from the dial side.

The final prototype is amazing, though understandably the sound still has quite a bit of development work ahead. It shows much promise...

Oh ... well, then ...

I hope its acoustic qualities will eventually meet its optical ones. For me, your little AP Sonnerie en passant is still a reference ...

Marcus

Totally convinced by the acoustical virtues of the " 11 ".

 
 By: amanico : January 25th, 2014-03:57

That was my major question, what I heard enchanted me. I didn't hear the Patek MR in the real, but, except ( maybe ) Patek, the nicest I've heard. Loud, pure, rich, the compromise is impressive.

Best,

Nicolas

The ref and caliber still have quite a bit of development work ahead of it...

Hi, Marcus,

MJLC was kind enough to allow me to spend some quality time with the (mid-development) prototype  and hammer and gong demonstrator, knowing that repeaters and striking watches - repeaters, sonneries en passant - are my passion and collection specialization.

I typically do not comment on prototypes, knowing that comments, good or bad, can be misleading and in some cases unfair (if ultimately inaccurate in a positive way, to the consumer - ie prototype good, final product bad; and if ultimately inaccurate in a negative way, to the manufacturer - ie, prototype bad, final product good) but in this case, because there seems to be such great specific interest and because I can fairly and reasonably comment without risking too much inconsistency with final production (I hope!) I will offer a few thoughts.

The prototype shows great potential - the strike, though still needing much development and tuning, showed its potential with a pitch, timbre, and tone that were nice, especially considering it is a prototype. Volume and regulator noise were both good to very good, with promises that they would be excellent to great once it reaches production.

The idea of the trebuchet hammer - double articulation in the strike action of the hammer - is an intriguing one that has already been tried in another (yet still to reach "full production") model, which I have not yet heard. (sonnerie Grande Complication) and if executed right, could be a revelation. At least it is a great engineering concept.  I did remind those in the room that ideal volume vs tone quality are not linear or even always linearly correlated with speed or strength of strike, ie the harder, the more forceful the hammer strike, the louder the tone without sacrifice in tone quality ... this is NOT true. 

Also, the idea of the hammer and square gongs having "fuller contact"  on impact vs point contact on a round gong (ie, point contact on a radius, or tangent point) - the purity of tone and its "tail" is as much a function of the RECOIL of the hammer from the gong after the strike so the gong can develop fully its vibrations, hence its "music"; as it is a function of the initial strike itself (force, contact area) Afterall, the "music" is from the gong vibrating AFTER the strike, and not from the strike itself, per se.  So hopefully (and I'm sure they will) MJLC conceptualizers and constructors will take these points into consideration as development continues.

Cheers,

TM

Aaah, I see you had the privilege to listen to the two watches...

 
 By: amanico : January 29th, 2014-11:37

The proto and the demonstrator. wink

Yes, the proto needs some development in terms of finish and acoustics, but it sounds promising.

The demonstrator is more spectacular, acoustically.

The regulator was quite silencious, I was impressed by that. Even more than on my MMR.

As for the sound, its purity and richness are quite remarkable.

One thing I had in mind with the pusher and the locker, Thomas... One thing you could tell me, for sure: Didn't AP do something quite similar, in one of their round Watch? A Watch I had the pleasure to see when you wre in Paris? wink

Best,

Nicolas

Thanks! this is what makes repeaters so special - and expensive ...

 
 By: Marcus Hanke : January 30th, 2014-01:31
... since all this work cannot be executed on the CAD machine. You need knowledge, great experience and a passion for the creation of tones - and music, ultimatively. Your description shows that clearly.

I hope - and wish - that JLC will take the high road towards this kind of perfection, and not succumb to the temptation of selling a half-finished product, from the acoustic point of view.

Regards,
Marcus

They cannot take the half way. They will be judged through the HM 11. [nt]

No message body

My problem is ...

 
 By: Marcus Hanke : January 30th, 2014-06:04
... that  won't be able to have the joy of listening to all these great chiming watches aside. AFAIK, in whole Salzburg there is not one dealer having a wristwatch repeater which I could inspect.

Marcus

I am out and can't concentrate much....

 
 By: moc : January 10th, 2014-03:42
I will have to read carefully and get back to you later. 

I am excited! A lot.... Wow!

Mo

Just a quick note.... Probably I would ve preferred

 
 By: moc : January 10th, 2014-03:49
Without tourbillon ..... To make it more pure, but it's a marvel, well done Jlc...

Talk later

Mo

I agree with you, Mo... Sometimes less is more.

 
 By: amanico : January 10th, 2014-04:07

But we are very picky, aren't we?

wink

Best,

Nicolas
