This Fukushima manufacturer boasts world class precision metal processing technology.
The manufacturer has been highly praised for its tradition of using "Sallaz" polishing techniques to create luxury watch cases.
The stainless steel blanks are first heated to approximately 1,200°C using a blast furnace. They are then forged by repeated hammering in eight differently-shaped molds, in a process called forging. This increases the density of the metal creating 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.
In 2011, it was awarded the grand prize in Fukushima Prefecture’s 4th Utsukushima Monozukuri competition.

AT-38

AT-38

¥50,000~ (3 colors)

Knot’s flagship model, the AT38, 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 two users who have abandoned them.
With its Japanese-manufactured high-precision, high beat movement; its case, born out of the advanced metal processing techniques adopted by the country’s finest mechanical watches; and its clock face, manufactured in Japan, in an age where almost all domestic dial production has ceased…. The AT38 is a crystallization of the passion of Japanese watchmakers; an authentic, affordably-priced, Japanese-made mechanical watch that Japan can be proud of.
