A dial crafted in the pursuit of elegance

The dial adopts a minimalist design.
Without sacrificing legibility, it shows various expressions only by the three-demensional design of the metal parts, without using any printing.
The light gray color of the dial is reminiscent of a scenery of the forests of the Shinshu region, covered with snow.
The logo and minute track are engraved, and the indexes and hands, made of white gold, produce a subtle light across the surface.

Refined beauty produced through the skills of master craftsmen and women

Flexibility and tension are combined in its shape, producing light that plays across a subtle ridgeline. It is reminiscent of a polished jewel.
Platinum shines brilliantly with no distortion, creating a highly refined aesthetic.
