The dial has a complex two-layer structure, and expresses depth and three-dimensionality by making full use of advanced precision processing technology that does not feel the boundary with the movement.
The movement is Orient Star's first automatic movement equipped with a silicon escape wheel, achieving 60 hours of operation and high precision of +15 to -5 seconds per day.
The case made of stainless steel (SUS316L) and the bezel with unique hexagonal screws are based on a delicate grain finish that emphasizes the unity with the dial and movement, and the mirror finish by Zaratsu polishing is an accent.
This model combines a metal band made of the same material as the case to emphasize the solid texture of the metal.
