It is equipped with a mechanical movement that is popular among wristwatch freaks, a see-through back that allows you to see the beautiful rotation of the rotor, a screw-in crown that does not allow water to enter, a 200m water resistance function, a unidirectional rotating bezel, and highly recognizable indexes. The hour, minute, and second hands on the face have a wide design with a high sense of presence. The visual impact is designed to catch the eye in its simplicity. The beautiful automatic hands are a perfect match, and will make your face light up every time you check the time. The hour and minute hands as well as the indexes are decorated with luminous paint to enhance visibility at night or in dark places. The indexes are lowered by cutting the dial, making it different from the applied type. The stainless steel with hairline finish is not overly assertive, but creates a sense of luxury and nuance for adults with good taste. It is available in three colors: black, white, and ocean.
