The skills that have been cultivated as a behind-the-scenes force in the Swiss watch industry for a long time have finally been realized.
We have released a number of amazing mechanisms as our own products that have amazed the world.
In the early 2000s,"Master Minute Repeater"

In terms of the technical aspects of mechanical watches, the most difficult mechanism is the striking mechanism.
In other words, it is a "minute repeater," and it uses two hammers to
The gongs that surround the outer periphery of the movement are struck regularly,
The time is indicated by sound, but due to the characteristics of the watch's structure, in order to make the sound resonate more strongly,
It requires space. Conventional products are placed on the back case side where space can be secured.
We researched the quality and quantity of sound and commercialized it, but unlike the tourbillon mechanism,
On the surface, it looks like a simple two- or three-hand model, and there's nothing particularly impressive about it.

there,Jaeger-LeCoultreWith a reversed concept, we rearranged the front and back of the structure,
By partially skeletonizing the dial, the two hammers are made visible,
Activate the repeater and have it strike two different times without removing the watch from your wrist
You can now admire the hammer.

This innovative structure is not just a superficial entertainment element,
This is a groundbreaking mechanism that enhances the essential volume of the minute repeater.
The gong that surrounds the outer periphery of the movement has been eliminated, and the surface crystal glass has been replaced.
We invented the "crystal gong," which acts as an acoustic speaker, so to speak.
This mechanism, based on a genius idea, is so logical that it will make you go "wow!"
The characteristics of crystal glass are that the surface is smooth, hard, and uniform, so when sound waves hit it, they are strongly reflected,
Increases the reverberation.
This resulted in the creation of an original striking mechanism with a strong and loud sound.

Another trendy complication that was representative of the early 2000s was the long power reserve mechanism.
It was the company's main creative force that created this mechanism, and it was their specialty.
The ultra-long power reserve mechanism with a double barrel provides an astounding 15 days of power reserve.

There are three advantages to this ultra-long power reserve mechanism:
First, it is convenient as it does not need to be wound for about two weeks.
In fact, it's over-specified and will last for an extra 17 days (lol).
The official limit of 15 days is based on the torque applied to the mainspring during use.
The timekeeping accuracy is maintained at approximately 15 days.

The second is that the amount of winding required for manual winding is about 2 hours, compared to the usual model.
The main drawback of other companies' long power reserve mechanisms is that they are almost the same.
The reel has a lot of winding capacity, so much so that you get calluses on your fingers, and it's heavy, so it's very tiring.
The company has a very comfortable winding feel, with a small amount of winding,
Moreover, it is equipped with a slipping attachment that prevents the mainspring from running out of wind, which is the biggest weakness of a hand-wound watch.
Even if the power reserve indicator reaches its maximum value of 15 days, the watch will continue to run freely without stopping winding.
It is designed with usability in mind.

The third feature is that it also comes with a torque indicator.
Not only can you see the amount of movement from the mainspring, but also its quality, thanks to the scale.
It is now possible to use it while checking the appropriate strength.
This is an outstanding technology for an ultra-long power reserve model in this class.

Finally, this Japan-only model is very special in that it is fully skeletonized.
This is a special model with only five units available, and is an attractive model that completely eliminates the dial, allowing you to see the mechanism working from the surface.
