The color theme, "Earth Color," is reminiscent of natural materials such as grass, trees, and soil, and is easy to match with a wide range of fashions, a trend that has been continuing in recent years. The earthy brown leather is easy to match with any fashion, and the subtle radial pattern on the dial gives a sophisticated and intelligent impression. The leather is sourced from tanneries that have received environmental certification from the LWG (Leather Working Group), an international leather auditing organization.
