Since 2007, and the unveil of the first Duometre, the " A Chronographe ", this is a long journey I invite you to re discover, through a particular aspect, the movements.
We can objectively say that the movement is the core part of the Duometre, due to its concept, the two barrels with their respective gear trains, which justified the Slogan " One watch, two brains ", and the horological appellation " Dual-Wind ".
It is not only the horological concept, it is also a very pleasant level of decoration: Made of german silver, the plates and bridges receive a " cotes soleillées " finishing and some anglages, and the Manufacture didn't forget the perlage, nor the heated blue screws. Let's add that all the Duometre movements have a large balance wheel, which is something as nice as it is appreciable, and that all beat at the pace of 21 600 vibrations per hour.
We are facing some nice movements, here, respecting the tradition of " Belle horlogerie ", even if we would have appreciated some deeper anglages, but at this level of price, if we compare with the rest of the modern production, the Duometre is a fair and very interesting offer.
That being said, let's start the journey.
1/ 2007: " A Chronographe ", Cal 380 ( 390 parts ).
One of the most interesting Duometre ( even if I wonder if there is a Duometre which is not interesting ), because it is the first one, because it is conform to my golden rule when it comes to Belle Horlogerie ( One case, one movement ), because there are not that many fine chronographs on the market.
2/ 2009: Hybris Mechanica à Grande Sonnerie, Cal 182:
THE superlative Duometre, with its 1600 parts, a TRES Grande Complication " offering " a first class striking watch ( Grande Sonnerie / Petite Sonnerie / Minute Repeater ) and a very nice level of finishings.
It required 3 years and a half to JLC to deliver the first watch, but it takes 9 months to assemble all the parts of the movement, and 3 more months to control the assembled watch.
3/ 2010: The Duometre à Quantième Lunaire, Cal 381 ( 369 parts ).
As it name doesn't suggest it, the main feature is not the Moonphase, it is not specially accurate, like on a perpetual calendar or in some other much more performant moonphases, as it gains one day each two and a half year or three years.
No, its main and hidden purpose is... Chronometry.
Indeed, when you pull the crown to set the time, the two second hands ( foudroyante and main second hand ) are hacking and reset to zero WITHOUT stopping the balance wheel.
Here, the second barrel is dedicated to the balance wheel, to avoid any pollution which comes from the time, date and moonphase.
That is the big interest of the Quantième Lunaire.
4/ 2012: The Duometre à Spherotourbillon, Cal 382 ( 460 parts )
The Cal 382 is an ode to precision and magic.
Precision, because it is the first Tourbillon adjustable to the nearest second, with a stop second which flies back to zero with the pusher located at 2 o'clock, and, very interesting, with a variation of amplitutde which has been reduced somewhere between 8 and 10 per cent.
Magic, for two reasons. One is obvious when you admire a Spherotourbillon in the flesh: The Ballet of the regulating organ is captivating.
The other is about the level of finishing. The anglages are deep, sensual, impressive.
And let's keep in mind that you can also travel with it, as it offers you a second time zone!
5/ 2013: The Duometre Unique Travel Time, Cal 383 ( 484 parts ).
The Cal 383 plays a big part in the fact that the " UTT " is simply a new milestone in the category of travel time watches, and the most sophisticated among this family;
Here, you have a digital AND jumping time zone hour, you can set the time by increments of one minute, independantly of the home time, you also have a day night indicator which perpetually turns, and you can reach your time zone forward and backward thanks to the two pushers located at 8 and 10 o'clock.
The second is hacking, but not resetting to zero.
And the finishing is common to all the Duometre, very pleasant to see.
6/ Duometre à Spherotourbillon Moon ( 2015 ) :
Precision of the Time, precision of moonphase.
The Cal 389 adds a moonphase to the Cal 382, a moonphase which is accurate to one day each... 3887 years.
Made of 476 parts ( 16 more parts than in the Cal 382 ), its power reserve is 5 hours shorter ( 45 hours, versus 50 hours for the Cal 382 ).
The date disappeared in the " Spheromoon ", not the second time zone.
CONCLUSION:
Each Duometre brings something to Horology. Most of the time, JLC offers us something spectacular ( Chronograph / Grande Sonnerie / Spherotourbillon ), and when it is more discrete ( Quantième Lunaire ), it is not less interesting as it adds some good technical solutions to Chronometry, or it rewrites a well known theme ( UTT or Spherotourbillon Moon ).
This family provides some serious dizziness, when we think that in 6 years only, Jaeger-Lecoultre created these 6 watches.
It generates and authorizes some of our maddest dreams, as the family, albeit young, is already very rich.
I can't wait to see what the Jaeger-Lecoultre Team hides under his magic sleeve, and I hope I will be able to update this review!
Looking forward to reading your opinions and thoughts,
Long Life to the Duometre!
Best,
Nicolas
