An elegant expression of Japanese aesthetics. Eichi means wisdom in Japanese. The name reflects the fusion of Seiko Watch Corporation’s decades of Japanese watchmaking skills with the highest and most technically advanced Spring Drive movement. From the design of every component to the hand painting of the dial, the Eichi II is made by elite watchmakers at the Micro Artist Studio in Shiojiri, central Japan.


The 12-hour indices and Credor logo are meticulously hand-painted, one by one on the porcelain dial inspired by the snowy landscapes of winter in the mountainous region of Shinshu. The irregularities that betray the hand-executed nature are visible only under extreme magnification- a true hallmark of the hand painted process. Over twenty steps are required to create the blue steel hands and case back screws used in the Eichi II. Each hand is tempered individually by a single craftsman. When heat is applied to the mirror-surfaced parts, the surface colour changes in the oxidation process. The blue coloration only occurs after a specific time, different from hand to hand. Years of experience and skills are required but our skilled craftspeople know exactly when to remove the hand from the flame to achieve the perfect shade of blue.


The deep blue colour used on the dial is known as ‘Ruri’ in Japan and elsewhere as lapis lazuli. A shade that entranced makers of jewelry and other objects d’art for centuries because of its intensity and its richness. It perfectly suits the simple, clean layout of the Eichi II dial and provides the ideal contrast to the white indexes and hands. It took over two years to develop this particular shade. The production requires each dial to be fired repeatedly, a process that takes place at the Micro Artist Studio under the close supervision of the studio’s own craftsmen. The dial has a gentle curve thanks to the careful application of the porcelain glaze which creates a surface tension, giving it a slightly domed shape. The very nature of porcelain leads to the glaze being slightly thinner at the edge and center of the dial so that, as light plays across it, particular shades and tones are revealed.


The manual wound Spring Drive Calibre moves the second hand in perfect glide motion creating a powerful experience of continuous flow of time. The case back is hand-finished by master craftspeople and features a timeless lustre and unmatched sophistication. The movement uses a two-piece bridge structure in a well-balanced position, finished simply and dynamically. The contours of the bridge and the bevelling look striking from any angle, as they are all expertly handcrafted and polished to a mirror-like finish with a circular motion. The circular mirrored finish parts and blue temper screws stand in contrast to the hairline finish of the bridge and heighten the sense of engineering perfection. The finishing was inspired by Philippe Dufour who famously consulted with the Micro Artist Studio on finishing techniques.
