SBGX361 presents a lighter expression of the winter landscape surrounding the Shinshu Watch Studio. Known as Skyflake, the dial takes inspiration from wind-swept snow beneath a clear winter sky, rendered in a soft, pale blue tone. Its delicately textured surface recalls the quiet openness of Shinshu in winter, where snow and sky seem to merge into a single, luminous scene.
Housed in a 33.0mm stainless steel case with a slim 9.1mm profile, the watch offers refined proportions designed for comfort and everyday wear. The compact case is paired with a dual-curve sapphire crystal and a finely finished bracelet, creating a seamless balance between presence and restraint.
Inside, Caliber 9F51 delivers the high level of precision for which Grand Seiko quartz is known, with an accuracy of ±10 seconds per year. The movement’s compact architecture allows for slimmer case dimensions while retaining hallmark technologies such as the Twin Pulse Control Motor for confident hand movement and a regulation switch for precise adjustment during servicing. Hand-assembled at the Shinshu Watch Studio, the movement embodies the same attention to detail found throughout the Grand Seiko collection.
The pale blue textured dial captures the calm of snow beneath a clear winter sky, expressing a lighter view of the Shinshu landscape.
The smallest and thinnest case ever created for a Grand Seiko 9F quartz watch, combining clarity with refined proportions.
Hand-assembled at the Shinshu Watch Studio, Caliber 9F51 offers ±10 seconds per year accuracy in a newly compact form.
