AT-38

A high-performance mechanical watch,
instilled with Japanese spirit and craftsmanship.

Japanese watchmaking techniques are gradually becoming a lost art. Manufacturing locations are being shifted to cheaper locations overseas, and there are now hardly any cases where the inscription “Made in Japan” can be seen on affordably priced mechanical watches sold in the country. Domestically produced mechanical timepieces are now limited to only a select few highly priced models.
Japan is renowned for its mechanical watches, yet very few people who would love to wear them are currently buying them. Is this an acceptable state of affairs for the Japanese watch industry? As the market decreases, the traditional watchmaking techniques also become increasingly difficult to pass on to the next generation.
Knot’s flagship model, the AT-38, was born out of that sense of crisis for the industry, and out of our desire to communicate the charm and appeal of mechanical watches to an audience that had abandoned them.
Made in Japan, the watch features high-beat movement with high precision. Its case is the product of advanced metalworking techniques used in the country’s finest mechanical watches. The watch face is also manufactured in Japan, in an age where almost all domestic dial production has ceased. Knot has combined all of the Japanese watchmaking techniques that were gradually fading away, creating a high-precision mechanical watch and offering it at an accessible price. The AT-38 is the culmination of the passion of Japanese watchmakers: an authentic, affordably priced, Japanese-made mechanical watch.

“Sallaz Polishing” is synonymous with luxury Japanese-made mechanical watches
A clear mirror-finished case, polished to perfection by the hands of skilled craftsmen

The case of AT-38 is produced by Hayashi Seiki Seizo Co. Ltd., a company that manufactures watch cases for Japan’s finest mechanical watches. The base material is 316L surgical stainless steel, an ultra-pure stainless steel used for applications in the medical field worldwide. Our watch cases are manufactured from start to finish at Hayashi Seiki Seizo’s production plant in Sukagawa (Fukushima prefecture), starting from the blanking of a stainless steel plate. The stainless steel blanks are heated to approximately 1,200°C using a blast furnace, and then molded by repeated hammering into eight different shapes in a process known as forging. This increases the density of the metal to create a strong, hard case.

The mirror-polishing technique that gives the hard, rough-edged cases their beautiful even finish is Hayashi Seiki Seizo’s world-class “Sallaz” polishing technique. This Sallaz polishing is rarely used even in luxury Japanese watches, and there are few expert craftsmen in Japan with the high level of skill that the polishing technique demands. The ability to achieve different looks from the same material by carefully polishing each part is an advanced technique which can be performed by Hayashi Seiki Seizo thanks to its specialist engineers.

Non-reflective,
coated sapphire glass

The crystal of the AT-38 utilizes the same level of sapphire glass with anti-reflective coating that can be found in luxury watches. The coating is on one side only, which increases the visibility of the clock face while at the same time minimizing discoloration of the glass.

The sign of a high-performance timepiece
: high-beat movement

For the movement – the watch’s beating heart – Knot has adopted the Cal.9015 high-beat movement from CITIZEN MIYOTA, made in Japan. This high-beat movement oscillates 28,800 times per hour (8 times a second), reducing the distance of the swing of the second hand and drastically increasing the precision of the watch.
The Cal.9015 is a thin, high performance 8-beat movement, and the first mechanical movement to be revived by MIYOTA in 30 years. It has a thickness of just 3.9mm.
The AT-38 makes maximum use of the features afforded by the Cal.0915 movement, fitting the components into a case 38mm in width, the standard for a dress watch, while at the same time achieving a total thickness of 10mm. In addition, the transparent back cover of the watch case allows the wearer to see the internal workings with their own eyes.
