Automatic model


It is a watch called impossible.

MADE IN JAPAN, where have you gone. Most of domestic mechanical watches are now available. It was made overseas with low manufacturing cost. I see the engraving of MADE IN JAPAN, It will be only some high class mechanical watches.
Decrease in opportunities to get, Even the succession of technology was reduced.
So. Watch making in Japan, Manufacturing is on the verge of extinction. Make the future of manufacturing. That is the spirit of Knot treasure. Mechanical expression that anyone can get at, It becomes a support for manufacturing.
And it was born, mechanical clock AT-38.
It is mechanical chronograph ATC-40. How is this part? This technology? This price?
Everyone enables what seems impossible. Movement, case, dial to everything, Japanese technology that has been lost is alive. Of course, at a price many people can reach.
Everyone, please take it for yourself. Knot's mechanical watch.
It was a watch called impossible.

“Limited Model of the year 2021”, VINTAGE.

Mechanical watches have been used for generations and are marketed as antique watches, where their charm continues to shine. The vintage texture of the watch, which is aged and tarnished, gives it an austere look and makes it a special gem. We have recreated this charm in our latest model, which is made with modern technology and the soul and work of the Japanese people.




Make a beautiful contradiction, design.

Make one contradict one.
That is the design concept of the ATC - 40.
Two elements overlap each other, aim for exquisite balance.
For example, case. Dare to cut the body to the body,
I confined heaviness and lightness inside a 40 mm diameter.
In addition, dial. Three kinds of in-dial,
In pursuit of functionality, to direct gracefulness
Font adjustment in micrometers is done.
Design that combines static and dynamic,
you do not choose the scene.
From business scene to active scene.
With your arms, keep keeping time.
Knot's chronograph has a beautiful contradiction.

The movement,
Even clock artisan moved.

If you use this movement, I definitely want to make it together.
Watchmakers and partners cooperating with Knot,
I said so to you in front of the movement in front of me.
It is hard to see even domestically produced luxury watches,
Mechanical chronograph movement.
Its existence is special among watchmakers.
A super complex mechanism with approximately 310 parts,
which is twice as much as normal.
High beat of 28,800 vibrations per hour.
There is an overwhelming mechanism to make the men's hearts hot.
Tick tick .... When the ears pass, the parts are singing beautifully.

We adopted vision polishing.

Our mechanical watch case,
It is finished by some special polishing.
Hayashi Seiki manufactures technology partners.
We produce several mechanical types of the highest peak in the country.
Production of the case is close to Japanese sword making.
Train ultra-high purity stainless steel with high heat, hammer and train.
I repeat it, a case with high metal density is born.
And finishing is the vision polishing technique "Zaratsu polishing".
In the past, it was also used for Swiss luxury watches,
but Advanced skill is required, and now I rarely see it.
With Hayashi Seiki Manufacturing which holds many skilled craftsmen,
Grind each one politely, to a beautiful specular surface without distortion.
It made the impossible possible, it is shine.

  • DETAIL 1:

    Two holes

    You can enjoy a separate type in the hole on the top and a strap with a pull-through type in the bottom hole. It stabilizes the center of gravity balance of the whole clock and enhances fitness to the arm.

  • DETAIL 2:


    As with the side of the case, a satin finish is also applied to the inside of the lug. By spiritlessly using techniques of craftsmen to detail, it produced sophistication and quality.

  • DETAIL 3:

    Sapphire glass

    Like AT-38, it adopts high-hardness sapphire glass next to diamond to windshield. By applying antireflective coating only on one side, it improved scratch resistance and visibility of the dial.

  • DETAIL 4:


    The index adopts a trapezoidal bar with a solid feeling that is compatible with a heavy case. By finishing metal rings and fonts to the utmost limit, we expressed a refined and heavy worldview.
