+ amplitude
The chrono mechanism still needs to be switched in and out of the control of the escapement. Sorry, my question concerning amplitude should have been reversed: there are 2 power flows, both controlled by a single escapement, so the impulse should increase (?!) when the chrono functions is engaged...
Technical Draws of the Duo Metre.
" One Watch, 2 Brains " says the ad... I found these draws in my H.D, and wanted to share them with you, as we spoke a lot about the Duo Metre, these last months, and to beeter understand how it works. Here are the pics of the movement: The Balance Wheel ...
Ahh, that last shot is a beauty mon ami
Hopefully, i might see it on my wrist soon! But in any case, good watch you have there, and wear it always in the best of health! A bientot Stephen
Hope so, Stephen!
I'm sure you will adore it.. Platinum case, gorgeous manual wind movement, and stunning dial. It is made for you! best, my friend. Nicolas
I just love the idea ...
of the ligthning seconds wheel !!! Simple, elegant, ingenious ... The watch is beautifull, as a watch and as a concept. Thanks Nico (Until I can afford one ... do you think JLC would agree to sell me just that seconds wheel ? I would just mount it on a gl...
Thanks for posting this Nicolas.
Very interesting seeing the workings of the Duometre and having it explained graghically; this unusual and unique caliber. Cheers Fernando
Nice selection of images
It is always good to see the different perspectives on the Duometre. Thanks for posting these. That last photo is really beautiful. This is one of the reare instances where I think every one of the three variant metal versions looks equally gorgeous. How ...
Bravo JLC,well done,Nicolas.
Hi there, Execellent write Nicolas. Duometre is already a Execellent example of modern master piece by JLC,i would simply say no excuse to not have one as a watch lover by nature. Nicolas,again perfect illustration in detail and a great job,well done. Hop...
JLC does it once again...
yes we have seen this all before.. but with an achievement so great.... gotta give them a round of applause again.
Gr8 prentation of a watch with a high IQ!
Ur way of educating makes a complicated movement a bit more simplified and therefore better understood. Thanks again Nicolas, Best always my friend, Matrix.
And i still like the RG version more ...
..... LOL Nicolas, this Pt piece must be stunning too .... When i first saw the pics of this one it gave me a strange (positive) feeling .... next time we meet i must handle it (let's hope i don't drop it .....). Greetz, Philippe Bimbaeno
Thanks for these great report
I thank you that now I know how this amazing caliber works. Is really a pleasure see what JLC can make... a really work of art and a really technical and superb movement. I´m very happy to see that you have this Duometre, mon ami... it must be an honor we...
Nice work, Nicolas + amplitude?
Thank you for posting. Is any information available as to the advantages of the 2 mainspring barrels? Is there reduced amplitude drop when engaged? Lovely looking movement....Again....from JLC
BLDJ, here are some answers
In the Classic Chronograph system, the Chrono shares its energy from the same barrel. Here, with this Duo Metre, there is no need for a coupling clutch for the Chronograph functions. So, there is no interference on the rate of the watch when the Chronogra...

There is no reduction nor increase of the impulse, BLDJ.
As the barrel of the Chrono has its own energy, energy which was given by the common escapement. So the barrel is like a tank, which was efilled by the escapement. Once refilled, there is no influence on the rytthm of the impulse. Best. Nicolas
Once again, thank you, Nicolas
Thanks again for taking the time to respond. Like all new movements, I think I will have to stare and stare at it until I understand. Pieces like this is why I admore JLC so much. Do you have any more movement diagrams to help my staring efforts.
The beveling and finishing work on this movement looks to be
JLC's finest attempt to date! Beautiful watch!
The nicest or one of the nicest, Fred?
I'd say one of the nicest, if you compare it to some very tempting creations, like the Reverso Platinum Tourbillon Skeleton, the Gyro I and II, or the Perpetual Calendar Skeleton for example... PC Skeleton: Reverso Skeleton Tourbillon: Gyro II: Gyro I: Ag...
Thanks for sharing those Nicolas!
I really enjoyed seeing the skeleton Touby. It has a blissfull simplicity to it. I hope I can see one in flesh someday! Kind Regards, Fred Bonatto
What an amazing timepiece !
and another extremely well documented post, thanks ! Cheers Jeff
If you want to know more - Dje had already posted some of these technical drawings before

Hadn't seen that. Thanks
Now I just have to stare at the pictures for a while to work out how the power flow from the barrels doesn't alter the impulse.
