No malfunctions. This is an automatic mechanical wristwatch from Knot, a brand that is committed to being made in Japan. Automatic model AT-38 A high-performance mechanical watch infused with the soul and craftsmanship of the Japanese. Japanese watchmaking technology is on the verge of disappearing. Manufacturing bases are shifting to cheaper overseas locations, and it's becoming increasingly rare to see the "MADE IN JAPAN" stamp on real-price mechanical watches sold domestically. Only some high-end mechanical watches are still produced in Japan. Japanese-made mechanical watches. But the Japanese, who should truly cherish them, aren't buying them. Is this acceptable for the Japanese watch industry? Furthermore, as the market disappears, the transfer of technology becomes increasingly difficult. Knot's flagship model, the "AT38," was born from a sense of crisis in the industry and a desire to convey the appeal of mechanical watches to Japanese users who have drifted away from them. It features a high-precision, high-beat movement made in Japan, a case produced using advanced metalworking techniques employed by the highest-quality domestic mechanical watches, and a dial manufactured using techniques that are rarely seen in Japan anymore.
