Product Specifications

Product Features
9F quartz model with independent time correction function for the hour hand
Equipped with the new quartz caliber 9F85, which has an independent time correction function for the hour hand. By moving the hour hand independently without stopping the watch, time differences can be corrected without losing the high accuracy of a quartz watch. Long, sharp-looking hands and finely beveled three-dimensional indexes improve legibility. The calm navy blue dial, combined with the standard case design and size of 40mm, makes this watch suitable for any occasion. This watch is a member of Grand Seiko's new Heritage Collection, which has an imposing presence despite its slim profile.

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, we combine cutting-edge technology with the highest level of craftsmanship. 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.
