Capturing the essence of the seasons
The natural world is ever-present at the Grand Seiko Studio Shizukuishi, where this watch and all other mechanical Grand Seiko watches are made. The studio is tucked away in a quiet forest in northern Japan with the 2,000 meter high Mt. Iwate on the skyline, so it is no surprise that the team of TAKUMI, or master craftsmen and women, who bring these watches to life are influenced and inspired by the beautiful landscape that they see every day and by the ever-changing vistas that the seasons bring.
Kishun, the first days of summer
Powered by the slim, hand-wound movement, Caliber 9S64, this watch is the epitome of simple refinement. The dial is simple and clean but, when viewed through the sapphire case back, the intricate perfection of the engineering of the hand-assembled and adjusted movement is abundantly and satisfyingly clear. Thanks to a long mainspring and a balance both made of a proprietary metals, this watch has a high and stable accuracy rate and a power reserve of 72 hours. The dial is in a delicate shade of pale blue, the color of the skies above Mt. Iwate as summer begins, the season known as Kishun.
