Product Features
Royal roadside design in midnight blue color
The dial color is midnight blue, which is close to black, and the model is equipped with Spring Drive, adopting Grand Seiko's royal road case design. The movement installed is Seiko's original Spring Drive. The second hand, which glides across the dial without sound, is one of the unique features of Spring Drive. The natural movement of the second hand, as if in harmony with the flow of time, is achieved by IC control. The maximum winding time is about 72 hours (about 3 days), and the remaining duration can be checked on the power reserve display on the lower left of the dial.
Grand Seiko
Manufacture
Grand Seiko is a true manufacture that handles everything from movement development to design, manufacturing, assembly, adjustment, inspection, and shipping. In an environment where every single component can be researched and developed from the raw materials, cutting-edge technology and the highest level of craftsmanship are fused together. Grand Seiko Studio Shizukuishi overlooking the majestic Mt. Shinshu Toki no Takumi Studio is surrounded by the mountains and lakes of Shinshu. Three movements are created at these two studios, both of which are surrounded by the rich natural environment.
The Spirit of Takumi
Grand Seiko's craftsmen are in endless pursuit of the essence of time. This is similar to the “way” of the ancient Japanese martial arts, tea ceremony, and flower arrangement. By refining one's skills and deepening one's spirituality, the path is further sharpened and opens up new frontiers. In order to embody the ever-changing time in our timepieces, we must master the art of high precision, legibility, and beauty of form. To create a true ideal watch that will shine forever beyond generations. There is no end to the challenge of our craftsmen.
Light and Shadow
Japanese people delicately sense, appreciate, and love the myriad expressions of light and shadow created by the passage of time. Sharp, distortion-free planes and straight lines are the main form. The mirror surface has been elaborately polished by the skill of a master watchmaker. The multi-faceted cut indexes and bold hands. The symbolic designs are created to shine brilliantly while maintaining high legibility, creating a beautiful expression each time when the light changes depending on the time and place.
