Mechanical 3Days with calendar function in a powerful case of increased size
This model is equipped with a large diameter mechanical self-winding movement "Caliber 9S68" with a convenient calendar function in a 42mm case with a strong presence.
Despite the large size of the case, the design has a clean silhouette when viewed from either the front or the side by narrowing the tip of the crown.
The strong, three-dimensional indexes are in harmony with the presence of the case, creating a well-proportioned and imposing appearance. The simple silver dial, which evokes the identity of Grand Seiko, enhances legibility by suppressing radiation.
