The dial has a deep blue color that captures the alluring beauty of the full moon in the night sky above the Shinshu mountains that can be seen from the studio in Shiojiri where this and all Grand Seiko Spring Drive watches are created. The sunray pattern catches the light at every angle and recreates the gentle sparkle that the moon casts over the landscape when it is at its very highest point in the sky. The signature glide motion seconds hand of Spring Drive is in a gold color and captures the grandeur of the night sky as it sweeps silently across the wide dial, bringing the wearer closer than ever to the serene and eternal nature of the passage of time. The minute and seconds hands are curved by hand so that they slope gently down towards the minute track at the edge of the dial, enhancing the legibility of the exact time. The watch is presented on a dark blue strap that harmonizes perfectly with the rich tone of the dial. 

SBGY009 is powered by the manual-winding Spring Drive Caliber 9R31. This movement incorporates an innovative Dual-Spring Barrel that contains two mainsprings set in parallel and so delivers a power reserve of 72 hours. The thinness of this movement, the slim construction of the case and the box-shaped sapphire crystal all combine to allow the craftsmen and women of the Shinshu Watch Studio to create a slim and classical design that captures the spirit of the original 44GS, while also achieving a low center of gravity that provides excellent comfort on the wrist.
The watch is offered as a limited edition of 1,500. Each individual serial number and the words ‘Limited Edition’ are engraved on the case back.
