Heritage Collection ‘icefall’ Hi Beat 1998 Revival

This creation exhibits a new dial pattern while inheriting a classic Grand Seiko case design. 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 bluish-white color.
