A new Grand Seiko creation powered by a high-beat movement offers a new perspective on the nature of time. The dial is inspired by the slender and strikingly beautiful white birch trees that thrive in northern parts of Japan and that grow in profusion near the Grand Seiko Studio Shizukuishi where this watch is made. With its intricate texture, fine detail and delicate subtlety, this new timepiece is a window that opens onto the distinctive natural environment of Japan and the exquisite craftsmanship of Grand Seiko.

The lasting beauty of the white birch forest is captured in the textured dial

Shirakaba. The white birch tree that thrives in Japan.

The watch captures the mood of the white birch tree forests near the studio where all Grand Seiko mechanical watches are crafted. In summer and winter alike, the tall, slender trunks and the white bark of the birch trees present a shimmering vista that is at once beautiful and mysterious. To look closely at the dial is to experience the exact same feeling that the visitor to these forests enjoys and to be brought closer than ever to the true and eternal nature of time.

The Series 9 Design. True to the ideals and traditions of Grand Seiko.

The overall look of the new creation is known as the Series 9 Design and it will be an important part of the Grand Seiko Heritage Collection’s signature in the years to come. Its powerful hands and grooved, prominent markers ensure perfect legibility, its Zaratsu polished, distortion-free mirror finish and delicate hairline finish alternate to give the case a quiet and harmonious glow.

The case has wide lugs and a low center of gravity that ensure that the watch sits easily and securely on the wrist. The Series 9 Design is true to the Grand Seiko Style defined back in 1967 with the celebrated 44GS, but its heritage is combined with a powerful contemporary feel that points towards a new era.
