White Birch Dial

The main appeal is the textured White Birch dial. Compared with SBGA211’s Snowflake dial, which expresses the quiet beauty of snow, SLGH005 feels more architectural, modern, and full of natural energy, inspired by the texture and vitality of white birch trees.

Mechanical Hi-Beat 36000

Unlike SBGA211, SLGH005 is not a Spring Drive model. It is a purely mechanical Hi-Beat watch, beating at 36,000 vibrations per hour. This makes it especially attractive for customers who want to enjoy the craftsmanship, rhythm, and emotional appeal of a mechanical Grand Seiko.

Made at Grand Seiko Studio Shizukuishi

Caliber 9SA5 is produced by skilled watchmakers at Grand Seiko Studio Shizukuishi, located with a view of Mount Iwate. This gives the model a strong Japanese craftsmanship story connected to Iwate, Japan.
