特点

The beauty of the natural world is palpable at the Grand Seiko Studio Shizukuishi, where all Grand Seiko mechanical watches are made. Located in northern Japan, with Mt. Iwate in the distance, master craftsmen and women bring watches to life in a place deeply in tune with the local surroundings. The watch features a new textured dial inspired by the ridges of Mt. Iwate. The first Mt. Iwate pattern dial appeared in 2006 and has since become deeply associated with Grand Seiko mechanical watchmaking. Mt. Iwate is one of the most active volcanoes in Japan; its history can be felt in the rugged mountainscape and the lava flow at its northern base. The dial of this creation captures the timeless beauty of Mt. Iwate as seen from the sky, with the striking light-blue hue evoking the purity of the air and water that surround this landmark.
The case and bracelet are made of Ever-Brilliant Steel, a stainless-steel alloy that features greater corrosion resistance than is typically seen in the watch industry today. It is powered by the Caliber 9SA5, which offers a power reserve of 80 hours thanks to the use of the highly efficient Dual Impulse Escapement and twin barrels.

Designed in the Evolution 9 Style

The watch has been shaped in the Evolution 9 Style, which represents a step forward for the Grand Seiko ideals of beauty, legibility, and wearing comfort while honoring a design language established in 1967 with the iconic 44GS. Zaratsu polishing to a distortion-free mirror finish alternates with a delicate hairline finish to impart a quiet and harmonious glow. The watch’s powerful hands and prominent, grooved indexes ensure the legibility for which Grand Seiko has become renowned. The case, with its low center of gravity, and a bracelet with the perfect width and thickness combine to ensure that the watch sits comfortably and securely on the wrist.

Ever-Brilliant Steel case and bracelet

The case and bracelet are made of Ever-Brilliant Steel, a stainless-steel alloy that features greater corrosion resistance than is typically seen in the watch industry today. Enhanced by the properties of Ever Brilliant Steel, the hairline-finished parts of the watch shine whiter than they would if formed from usual stainless steel. Their finish perfectly complements the light-blue dial, creating a harmonious design that shimmers beautifully on the wrist.

The movement’s finish inspired by the nature of Shizukuishi

The movement’s finish is inspired by the rippling waves of the Shizukuishi River near the studio where the watch is made.

Caliber 9SA5

Through the use of the highly efficient Dual Impulse Escapement and twin barrels, Caliber 9SA5 achieves approximately 80 hours of operation when the watch is fully wound even with its a high-beat rate of 36,000 vph. The movement also allows the watches it powers to be more lightweight through a unique horizontal ring construction.
