GRAND SEIKO SBGY009 tsuki tenshin Limited Edition


44GS inspired by the full moon over the Shinshu mountains. 2022 marks the 55th anniversary of the 44GS, which in 1967 introduced the unique design language that would guide the brand’s timepieces for decades to come—the Grand Seiko Style. In commemoration, Grand Seiko presents the 44GS 55th Anniversary Limited Edition reference SBGY009 featuring a dial inspired by tsuki tenshin, the moment when the full moon is at its highest point in the sky.

With SBGY009, the modern 44GS design is made slimmer due to the thin manual wind Spring Drive 9R31 caliber. This movement employs a dual spring barrel that helps keep the movement compact and achieve a greater power reserve of 72 hours. It is beautifully decorated with exposed jewels, tempered screws, and diamond-cut sinks.

The stainless steel case measures 40mm and houses a dial with a dynamic sunray press pattern that catches the light at every angle, recreating the moon cast over the landscape at the highest point in the sky.

SBGY009 is a limited edition of 1,500. Available Fall 2022
