Mechanical Watches and Hand-wound Watches About Jaeger-LeCoultre Master Control and Master Calendar

Jaeger-LeCoultre is one of the watch brands located in the Vallée de Joux in Switzerland, a region with a thriving watchmaking industry.

Currently, like IWC and Breguet, it is under the umbrella of the Richemont Group, and the brand's power is growing stronger and stronger.

Jaeger-LeCoultre's watches are characterised by simple yet elegant designs and high durability.

As we will discuss later, the Reverso collection in particular is well known for its durability and is synonymous with Jaeger-LeCoultre.

Of course, robustness and design are not the only features that distinguish Jaeger-LeCoultre.

The watches with Jaeger-LeCoultre's unique mechanism, the dual wing movement, represented by the "Duometre" collection,

Another major feature of Jaeger-LeCoultre is its high level of technical skill in making tourbillon watches, a type of watch that requires extremely delicate craftsmanship.

Jaeger-LeCoultre is one of the manufactures that carries out all of its production in-house.

We manufacture everything in-house and conduct extremely rigorous testing in-house, including a 1,000-hour control test.

Jaeger-LeCoultre always brings to the world watches of the highest quality, making it a brand among brands and a watch brand you can't go wrong choosing.

■ History

When you unravel Jaeger-LeCoultre's lineage, you'll be amazed at how far back in time it can go.

Pierre LeCoultre, who had the LeCoultre bloodline, arrived in the Vallée de Joux between 1530 and 1600.

He was a French Huguenot who had been persecuted and had come to Switzerland in search of a safe haven.

Later, Pierre's son built a church there and founded the village of Le Sentier in 1612.

Jaeger-LeCoultre still has its headquarters in Le Sentier today.

Time passed, and in 1833 his descendant Antoine LeCoultre opened a watchmaking workshop, forming the basis of the manufacture.

As an aside, the unit of measurement "micron" was discovered in 1844, and it was Antoine LeCoultre who discovered this unit.

This anecdote clearly shows how much Antoine LeCoultre wanted to improve the accuracy of watches.

In 1851, at the Great Exhibition in London, Queen Victoria of England purchased a pendant watch equipped with a LeCoultre caliber.

The mechanism of this watch was highly praised, and it won a gold medal, helping to raise LeCoultre's profile in an instant.

In 1858, Antoine LeCoultre's son, Elie LeCoultre, took over the family business and founded LeCoultre & Cie in 1866, marking the birth of the manufacture.

In 1900, Elie's son, Jacques-David LeCoultre, took over the management of the company, meaning that the manufacture had been run by three generations of father and son.

At last, the fateful encounter arrives.

In 1880, watchmaker Edmond Jaeger founded his company in Paris.

In 1903, Edmund Jaeger commissioned Swiss craftsmen to create what was then the world's thinnest watch, based on his invention.

Jacques-David LeCoultre, who completed the job, developed a close relationship with Edmond Jagger.

Edmond Jaeger, who supplied the movements for Cartier watches,

The more I used LeCoultre products, the closer we became to them.

A fateful meeting between Edmond Jaeger and Jacques-David LeCoultre led to the founding of Jaeger-LeCoultre in 1937.


1. Reverso

This is Jaeger-LeCoultre's signature watch.

This model has become a masterpiece that transcends the brand.

In 1931, when India was still a British colony, polo was an athletics sport that was widely played by the British.

Polo is a vigorous sport in which players hit a ball with a mallet while riding horses.

The British officer, whose intense exercise had caused him to break several watches, asked Jacques-David LeCoultre:

We commission the creation of a watch that is durable enough to withstand being hit with a mallet, and is also aesthetically pleasingly artistic.

That's why the Reverso was developed.

As the name Reverso suggests, the dial case is inverted, so the back case back is the front.

It is designed to withstand the shocks caused by vigorous exercise.

The case is square, giving it a beautiful appearance that oval cases do not have.

The price range is wide, with some models available for purchase starting from 300,000 yen.

2. Master

The collection includes various lines such as Master Grand Tradition, Master Ultra Slim, and Master Control.

The elements of the grand complication include the tourbillon and minute repeater.

This collection also includes timepieces with complications.

The Master Grande Tradition is a Grand Complication watch.

The Master Ultra Thin is a thin watch that is just 4.05 mm thick, rivaling Piaget's ultra-thin watches.

Master Control still produces the Memovox, a Jaeger-LeCoultre timepiece.

The Memovox was released in 1956 and was the world's first automatic watch with an alarm function.

In 1953, he famously gifted Charlie Chaplin a hand-wound Memovox.

3. Rendezvous

Rendez-Vous is Jaeger-LeCoultre's women's collection.

They are well-made, with some watches equipped with minute repeaters and tourbillons, and because they are women's watches,

The dial is studded with diamonds, making it a beautiful design that will catch your eye.

It is a collection that is also full of functional beauty.

4. Duometre

This watch is controlled by a dual wing movement, in which two independent mechanisms are driven by a single regulator.

The two independent mechanisms, each with its own power source and gear train, one powers the balance,

The other is a Jaeger-LeCoultre watch that controls the various functions.

5. Master Extreme

This collection features authentic diver's watches that are also used by the navy.

Compared to other Jaeger-LeCoultre watches, this watch emphasizes functionality over aesthetics.

This is a collection that exudes a different kind of toughness than the Reverso.

6. Geophysics

This is a new collection that uses a non-circular balance wheel called GyroLab.

This is a highly popular collection, which includes watches that are modern reproductions of models released in 1958.

7. Hybris Mechanica

Jaeger-LeCoultre has a collection dedicated to Grand Complications.

There are collections with celestial maps on the dial, collections that use calendars that even include leap years, and more.

This watch can be said to be the culmination of Jaeger-LeCoultre's technology.

8. Atmos

Atmos is not a watch.

This clock has a special power source; it runs on air.

This is another popular watch that has been around since its introduction in 1928.

A sealed capsule is installed, and the mixed gas inside the capsule expands and contracts according to changes in temperature, so no human intervention is required.

The mainspring is wound automatically.

Jaeger-LeCoultre watches have a strong image of being sophisticated watches for adults due to their design. Why not pick one up and experience the elegance of the brand?
