Design Philosophy

The Zaratsu polished finish used on the surfaces reflects light in a single direction, enhancing the sense of depth.
The satin texture of the dial is typical of the Japanese "shibui" aesthetic—simple but never simplistic.
Its slim case is among the models in the "dress quartz" segment of GS, where perfect proportions are achieved.
This model represents the mature phase of the quartz revolution that began in 1988: a period when mechanical discipline and electronic precision were blended.
