The dial showcases a form of Japanese craftsmanship, Urushi lacquer. The dial is made from long lasting Urushi that comes from trees grown in and around the town of Joboji that lies under Mt. Iwate, the mountain that dominates the skyline above the Shizukuishi Watch Studio. The black dial uses the lacquer mixed with iron to give it its distinctive deep jet black color.
High-legibility index decorated with a raised maki-e technique by the master of Kaga Maki-e Urushi, Isshu Tamura. The combined grace of the brush strokes of the Arabic numerals and the tension expressed by the markers emphasize the beauty and grace of the dial even more.
Only Joboji lacquer from Iwate Prefecture, the birthplace of the 9S Mechanical movements, is used. Domestic lacquer accounts for only a very small percentage of the lacquer used in Japan. Its handling is very difficult compared to foreign varieties, but it brings out deep black colors.
The combination of the dome-shaped dual-curved glass and curved dial gives a gentle feeling, while at the same time producing a strong sense of depth. This displays an expression unique to a mechanical model.
