For Japanese, black and white are seldom expressed in their extremes; there are numerous gradations between light and shadow. Shadow is as important as light because only with shadow can light be expressed. (Notice the shadow on this text)
On a perfectly polished surface, the play of light and shadow creates beautiful harmony. This interaction can be seen in traditional Japanese Shoji sliding doors. Even though these screen doors are constructed with simple straight lines and flat surfaces of paper and wood, the ever-changing interplay of light and shadow creates endless expressions of character.
The Grand Seiko Style is based on this Japanese sense of aesthetic. It is crystallized in an unique design language with highly polished smooth surface areas as the principle element. Today, even after half a century, the appeal of this aesthetic endures, attracting the admiration of watch enthusiasts around the world.
