Grand Seiko Heritage Collection "Skyflake" 33mm Quartz Watch- Ref. SBGX361

The Ethereal Beauty of the Winter Sky in Mid-Size Proportions

Experience the artistic mastery of the Shinshu Watch Studio with the Grand Seiko SBGX361, affectionately known to watch enthusiasts as the "Skyflake." This remarkable timepiece captures a sublime moment in nature, featuring a delicate, snow-textured dial finished in a serene sky-blue hue. Inspired by the image of fresh, wind-swept snow reflecting the clear blue sky above the Hotaka mountains on a crisp winter day, the dial offers a shifting depth that beautifully catches the light. This wintery landscape serves as a high-contrast canvas for Grand Seiko’s iconic diamond-cut dauphine hands and multi-faceted baton indexes, polished to a mirror-like sheen to optimize legibility in any light.

Setting a new standard for Grand Seiko's design engineering, the SBGX361 boasts a compact 33mm stainless steel case with an ultra-slim profile of just 9.1mm. This marks it as the slimmest and smallest case diameter of any 9F quartz creation in the brand's history. The classic mid-size case features seamlessly integrated lugs and alternate satin-brushed lines with signature Zaratsu-polished mirror surfaces, providing a comfortable, weightless feel on the wrist.

Beneath the dual-curved sapphire crystal lies the newly engineered Caliber 9F51, a high-end, no-date quartz movement handcrafted exclusively by elite watchmakers. Thermo-regulated to sample the ambient temperature hundreds of times a day, this exceptional movement achieves a staggering accuracy of ±10 seconds per year. Complete with a robust three-row stainless steel bracelet and a three-fold push-button release clasp, the SBGX361 "Skyflake" offers a perfect marriage of legendary dial artistry, comfortable dimensions, and grab-and-go precision.
