The SBGE257 features a dial that echoes the intense green of one of the 2,000 types of moss found in Japan. There is something eternal about the moss that thrives at the base of trees or on garden stones, often used in Bonsai to create the sense of time passing inexorably. This feeling is enhanced by the smooth, silent movement of the Spring Drive second hand as it glides continuously across the dial. Equipped with a GMT hand, this watch features Grand Seiko's exclusive Spring Drive caliber, combining the power of a mainspring like a mechanical watch with the high precision of a quartz watch. Its hands move in a completely smooth and silent manner without ever ticking. It is housed in a water-resistant stainless steel case with a ceramic bezel. It has a 24-hour GMT hand and Lumibrite indices for exceptional accuracy and legibility.
