Whatever happened to MADE IN JAPAN? Nowadays most mechanical watches found in Japan are manufactured abroad
where production costs are lower, with the MADE IN JAPAN inscription only seen on a select few luxury
models. This lack of availability also means that watchmaking techniques are being passed down the
generations to an ever lesser degree. That’s right – Japanese watchmaking is on the verge of extinction.
Knot’s core ethos is therefore to create the future of manufacturing, with the creation of a mechanical watch
accessible to everyone. Thus, the AT-38 mechanical watch was born. The ATC-40, Automatic Mechanical
Chronograph, is the latest addition to our range of mechanical chronographs. But how could these components
and this technology be offered at this price? We have achieved what many would have declared impossible.
From the movement to the case to the dial, the ATC-40 is the revival of Japanese watchmaking that had long
been lost, and at a price that many can afford. It’s time to experience it for yourself. The mechanical
watch by Knot: The impossible watch.
Two opposites fused into one. That is the design concept behind the ATC-40, bringing two
overlapping elements into a harmonious balance. Take the case, for example, which has been cut into the
body to create a 40mm diameter that conveys both lightness and a sense of weight. Then
there’s the dial. Its three sub-dials have been designed to be both functional and elegant,
with the marker fonts adjusted to the nearest micron. It’s a design that combines stillness and
movement, suitable for any occasion from business to pleasure, on your wrist
forever keeping time. Knot’s chronograph is a truly beautiful contradiction.
Movement that stirs even the watchmakers.
“If you use this movement, I want to work with you.” That’s what watchmakers said to us when they saw the movement we were planning to use. It’s a mechanical chronograph movement
rarely seen even in luxury Japanese watches, and held in exceptional esteem by
watchmakers. The mechanism is highly sophisticated with some 310 parts – twice the number
usually found – its high-beat movement oscillating 28,800 times per hour. It’s a
mechanism that will bring a smile to your face. If you listen closely, you can hear its
components singing in harmony.
Polished to perfection
The cases of our mechanical watches are finished with a special polishing technique
performed by our partners at Hayashi Seiki Seizo Co., Ltd. They manufacture many of the
finest mechanical watches in Japan, with the case refinement process bearing similarities to
Japanese sword making. Ultra-pure stainless steel is hammered and forged at high temperature, with the process repeated to produce a case with high metal density. The finishing touch is
a special polishing technique known as “Sallaz polishing”. It was once used for high-end Swiss watches,
but is now rarely seen due to the advanced level of skill required. Hayashi Seiki Seizo
is home to a formidable team of skilled craftsmen who carefully polish each piece to a
beautiful, undistorted mirror surface. The impossible has been made possible, and it shines.
Hayashi Seiki Seizo Co. Ltd. is a metalworking manufacturer based in Sukagawa, Fukushima Prefecture
boasting world-class precision metal processing technology.
The upper hole allows you to use a separate type strap, while the lower hole is for a pull-through NATO
type. This stabilizes the center of gravity of the entire watch and improves its fit on the wrist.
The lugs have a satin applied to them, matching the treatment on the sides of the case. Our artisanal
expertise has been applied to every detail, creating an overall sense of sophistication and quality.
Like the AT-38, the ATC-40 utilizes sapphire glass – the second hardest material after diamond. The
anti-reflective coating is applied to on one side only, increasing scratch resistance and visibility of the
