Limited Edition of 2,000 Pieces

Carry the Sea of Clouds on Your Wrist!

The Grand Seiko SBGJ275 is a masterpiece within the Sport Collection, limited to just 2,000 pieces worldwide, with 875 reserved exclusively for Japan. Powered by the HI‑BEAT 36000 Automatic Caliber 9S86, this watch embodies the precision and artistry that define Grand Seiko. More than a timepiece, it is a poetic tribute to nature, capturing the breathtaking beauty of the sea of clouds that surrounds Mt. Iwate at dawn.

The dial is inspired by the scenic views from Grand Seiko Studio Shizukuishi, where the organic pattern reflects the ethereal sea of clouds drifting across the mountain peaks. As light shifts throughout the day, the dial reveals new depths and textures, echoing the serene atmosphere of dawn breaking over Mt. Iwate. This artistry is paired with a sapphire glass bezel, enhanced by blue and white Lumibrite, ensuring optimal readability both in daylight and in darkness.

Collectors worldwide are already drawn to the SBGJ275 for its rarity and storytelling design. With only 2,000 pieces available globally, and nearly half reserved for Japan, demand is intense and future value is assured. The combination of technical excellence, natural inspiration, and limited availability positions this model as one of the most talked‑about Grand Seiko releases of 2026.

For those who seek not only precision but also a deeper connection to Japanese craftsmanship and nature’s poetry, the SBGJ275 offers a rare opportunity to “wear the dawn” on the wrist. It is a watch that resonates with collectors, enthusiasts, and dreamers alike — a true icon in the making.
