Sapphire crystal bezel

Using a bezel with a sapphire crystal ring set on a titanium pedestal, we carved 40 pieces of Edo Kiriko's traditional technique "Sen-suji". By shifting the center point of the radial pattern, light enters from an angle and creates a beautiful shadow. The coloring is a newly developed blue-black vapor deposition that expresses the transition of light.

[Processing procedure]
The sapphire crystal ring is polished and cut from the back side using the Edo Kiriko technique. By applying silver vapor deposition on the cut surface and peeling it off once, coloring remains only on the cutting line. In addition, the newly developed blue-black vapor deposition that enhances the saturation of blue creates an emotional shade with a faint purple color in the gradation. As a finishing touch, silver vapor deposition is applied to the entire back surface to enhance color development.

The beauty of Edo Kiriko
Make it stand out
Face design

The dial is finished with a highly colored black mirror to accentuate the beauty of the bezel. In addition, the in-dial is vapor-filmed in blue, and the in-dial ring (9 o'clock side) is finished in two-tone blue and black, creating a face design that matches the coloring of the bezel. In addition, city codes are engraved on the outer circumference of the dial to achieve both design and functionality without distracting from the beauty of the bezel.

Supporting the beauty of the bezel
Titanium case

The titanium case that supports the sapphire crystal ring uses titanium carbide treatment and rough polishing for the base part, resulting in a beautiful color and a carefully polished mirror surface with high smoothness. Furthermore, by applying gray IP to the convex part of the inner frame of the bezel, it creates a visual effect that makes the face look bigger.

In-dial solar

A non-transparent dial has been mounted by using a solar cell with high light-receiving efficiency and enabling power generation only in the in-dial area. Doing so allows for frees up more space on the dial for intricate design..
