Kurono Tokyo's new watch is inspired by Japanese swordmaking

Kurono Tokyo takes inspiration from the steel used in Japanese Swords for its latest watch, the Grand: Hagane. The watch features an urushi dial that has been hand-applied to replicate the finishing of the sword's steel. The watch features a 316L 37mm stainless steel case, a black calf leather band, a caseback that is finished with Kurono founder Hajime Asaoka's signature in kanji. The watch is powered by Miyota's 90S5 movement, which has a power reserve of 40 hours.
