Grand Seiko 60th Anniversary Limited Edition Hi-Beat 36,000 vibrations / hour, power reserve of 80 hours. The design has a distinctive look that marks a new beginning. The watch is naturally faithful to the original 1967 Grand Seiko model, the celebrated 44GS, but it differs slightly in aspects that are not limited to aesthetics alone. This new design features all the Grand Seiko hallmarks while also offering greater comfort and improved readability. Caliber 9SA5 represents a significant and decisive statement in the technical development of Grand Seiko.
