The watch pays homage to the famous 44GS from 1967 whose design was the first ever expression of the Grand Seiko Style. This set of design principles defined Grand Seiko once and for all and still inspires every new creation to this day.
The watch is powered by the revolutionary Caliber 9RA2 which offers a power reserve of 120 hours and a precision rate of +/- ten seconds per month. The movement is assembled and finished by hand and its finely polished bridge, blue tempered screws and power reserve indicator are all visible through
the sapphire case back.
It will be available as a limited edition of 550 at the Grand Seiko Boutiques and Salons worldwide.
