The dial of this model combines two distinctive elements: the deep indigo color known as katsuiro, the result of advancements in indigo dyeing techniques in Japan, and a dynamic pattern known as Iwao. The bracelet, composed of a series of rounded, intricately crafted links, perfectly hugs the slim, delicate curve of the case, following the movements of the wrist and creating a subtle shimmer. The movement powering this watch is the Caliber 9R31 Spring Drive, which uses a dual spring barrel to deliver a 72-hour power reserve when fully wound. Its exquisite finish is visible through the transparent case back, alongside the power reserve indicator.
