Jaeger-LeCoultre – Duomètre: the art of duality Replica Watches Young Professional

Double measure: it’s all in the name. Jaeger-LeCoultre’s Duomètre range is based on a particular principle of movement architecture, which is what defines the watches’ appearance. The watches have complications and parallel, symmetrical displays. This is nothing new in itself, except that here it is both a guiding principle and a horological choice.

Normally, watches are built on the principle of cooperation. The regulating organ, barrel and the gear train in between all work together, providing both accurate timekeeping and energy. The Duomètres don’t work like this. They all have two independent barrels, wound by a single crown. Each drives a different part of the movement, a complication. Jaeger Lecoultre Watches Wiki Replica has given this approach to movement and complication design the name of Dual Wing. The word “wing” here is to be understood in terms of the wing of a building, rather than the wing of a bird. Each barrel is engraved with the destination of its energy. The underlying idea is that every function has its own uninterrupted power supply. This means that the trigger, the jump, the critical moment for a complication never interferes with the balance wheel and thus the accuracy of its timekeeping.

Today, the range comprises five models, produced in a variety of different materials and dial colours. The first chronologically is by far the rarest. The Duomètre à Grande Sonnerie used to be known as the Hybris Mechanica, before this name was given to an entire range. It is one of the most complex models in watchmaking history, with 55 complications. It has one barrel for the time functions (hour, perpetual calendar, etc.) and another for a grande sonnerie with four gongs that sound the Westminster Chimes. The principle of partitioning the energy supply was extended to other models. In each case, the complication is rather special. They are so technically complex, in fact, that each Duomètre is virtually in a category of its own.

Technical features

If you are paying attention to the dates, a 1992 launch would make 2017 that the 25th anniversary of this Master Control collection. The opinion we’ve got here is actually part of a trio that includes the three core complications which have been from the Master Control collection as the beginning: time and date, chronograph, and traveling time. These aren’t really being labeled as a 25th anniversary collection, nor are they being promoted as this, but that’s essentially what these watches are and they are only going to be produced for this particular one anniversary season. I’m not going to go too in-depth on the other two watches in this collection, however, the chronograph is still worth a closer look. Even though the time-and-date watch is the one which drew me in instantly, I know a number of people that were all over the moon about the chronograph. It is a stainless steel chronograph with a two-tone sector dial for $8,000 — to find that in a vintage watch you’d probably be paying 10x, or even more. It’s worth noting that this version is 40mm, therefore not small, and it has a closed caseback, despite the automatic Jaeger motion inside. The deficiency of date and the glowing blue accents really put this watch apart and make it awesome.The last watch is the Geographic, which, I hate to say, just does not do it for me personally. I like the Geographic in general (I am a huge fan of travel watches), and I even like the 3-9-12 dial design. But, there’s simply too much going on here to get a sector dial. You don’t get to enjoy the dial up design due to all of the info packed in.Speaking of that, it’s likely worth defining here what exactly a business dial is and where it comes from. Loosely speaking, a business dial is defined by and takes its title from the so-called “industry,” which is the fundamental ring to the dial using radiating markers at the hours. In addition to this, industry dials may have other nested registers marking out various increments of time, either beyond the industry or in the dial’s edge. They are often two-tone, with the coloration inside the sector and away from the sector differing slightly.

The chronograph has a running seconds hand as well as a jumping seconds. The moon phase model gives the age of the moon in both hemispheres, alongside a jumping seconds. The Duomètre Unique Travel Time is a GMT watch with two side-by-side dials, one of which features jumping hours. Finally, the Duomètre à Sphérotourbillon has a retrograde calendar and a regulator with a tourbillon that oscillates at a 20° incline as well as vertically, combined with a cylindrical balance spring. As a bonus, it features a unique stop-seconds function that works independently of the tourbillon. In each case, energy supply is based on the dual-wing concept. The external display mirrors the symmetry of the movement inside the case.
