Inspired by the clear blue sky as seen from the top of Mt. Iwate
A limited-edition watch commemorating the 25th anniversary of the Caliber 9S mechanical movement.
Its design depicts the clear blue sky as seen from the top of Mt. Iwate, the soaring peak visible through the windows of the Grand Seiko Studio Shizukuishi, where Grand Seiko mechanical watches are assembled. A classic form prevails thanks to this creation’s mirror-finished bezel and case, gently curved lugs with Zaratsu polishing, and a box-shaped sapphire crystal. Inside is the Grand Seiko Caliber 9S66.
Assembled at the Grand Seiko Studio Shizukuishi by skilled craftsmen and women, the self-winding Caliber 9S66 is a GMT movement that runs for approximately 72 hours when fully wound.
