About this reference

This creation exhibits a classic mechanical Grand Seiko case design with a 40mm case size. The dial evokes an icefall that one might encounter in the dead of winter on Mount Iwate, the imposing peak visible from the Grand Seiko Studio Shizukuishi, home to Grand Seiko mechanical watchmaking. Such frozen waterfalls are natural phenomena whereby the water flowing downward gradually solidifies when the temperature drops below freezing. This fantastic scene is depicted on the dial through the dynamic and detailed pattern, as well as a unique icy-blue color. The case and bracelet are High-intensity titanium, a metal 30 percent lighter than steel and highly resistant to rust, corrosion and scratches.
