Introducing the No. 10 model from the Kyoto brand ``HYAKUICHI'', which is characterized by its profound yet simple face. Equipped with a mechanical movement that is popular among watch freaks, it has high specifications as a wristwatch, such as a see-through back that allows you to see the beautiful rotation of the rotor, a screw-down crown that prevents water from entering, a 200m waterproof function, a unidirectional rotating bezel, and highly recognizable indexes. The hour, minute, and second hands that run around the face have a wide design that gives them a very strong presence. The visuals were designed to be simple yet have an eye-catching impact. It goes perfectly with the beautiful automatic hand movement, and will make you smile every time you check the time. In addition, to improve visibility at night and in dark places, the hour and hour hands as well as the indexes are coated with sparkling luminous paint. The indexes are lowered one step by cutting the dial, giving it a different feel from the applied type. The stainless steel finish with a hairline finish gives off a sense of luxury without being too overpowering, giving off the nuances of an adult with good taste. Available in 3 colors: black, white, and ocean.
