A fresh perspective on the Nature of Time

This stunning Grand Seiko SLGH005 "Birch" is powered by a high-beat movement to offer 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.

Nine years in development and deploying all the skills and experience that Grand Seiko has gained over the past 60 years, the 9SA5 powering this reference is 15% thinner, more efficient, and more shock & wear resistant than previous generation Hi-Beat calibres, and is without a doubt the finest mechanical caliber Grand Seiko has ever created.
