Jaeger-LeCoultre Duomètre à Quantième Lunaire 40.5

I personally think that Jaeger-LeCoultre is a brand somewhat shadowed by Patek, Audemars Piguet and A.Lange and Sohne. I don’t think there’s a reason for this, it’s certainly not because they are making inferior timepieces – if anything it’s the exact opposite, they are making extraordinary watches. Perhaps they are just a gentleman’s after thought when it comes to selecting such a monumental piece – overlooked and underrated.

The following watch is truly something special, a breath taking construction of 367 moving parts in a 40.5mm pink gold case and sure to catch the eye of any man looking to purchase a serious watch. The Jaeger-LeCoultr Duomètre à Quantième Lunaire 40.5 is a watch with a name I still cannot and will not attempt to pronounce. Funnily enough it’s not the name that’s going to impress people, because before you’ve managed to say it they’ll be lost in your wrist watching this awe inspiring and quite frankly breathtaking watch busy at work.

The Jaeger-LeCoultre Duomètre à Quantième Lunaire 40.5 offers superb precision thanks to the hand wound Caliber 381 “dual-wing” mechanism that incorporates two separate power supplies. The first, regulated by the escapement and the balance, is entirely dedicated to the precise measurement of the passing of time; whereas the second source of energy is devoted to the display of the functions: hours, minutes, seconds, calendar and moon phases for both hemispheres.  The two are then regulated against each other via a jumping foudroyante seconds hand with zero/reset system, displaying elapse time with 1/6th of a second accuracy.

Honestly, to even comprehend what is going on in a tiny case on your wrist is truly unfathomable.

Above the hand finished movement is a gorgeous crystalline grained dail displaying all functions effortlessly, housed in a eloquent satin brushed 18k gold case and adorned with a chocolate alligator leather strap.

This piece was debuted at SIHH in 2012 and made a big fuss, most notably for its price tag. Now I’m not going to pretend $37,000 is cheap but watches from competing manufacturers with movements like this are going to cost you upwards of $100,000 thus making the Duomètre à Quantième Lunaire 40.5 a relative bargain. Watches are unbelievable inventions and this one in particular is a tribute to the industry. One of the most elegant and engaging timepieces I have seen in years. TVG applauds JLC.
