Grand Seiko Sea of Clouds GMT (SBGJ275)

The Grand Seiko “Sea of Clouds” GMT Ref. SBGJ275 draws inspiration from the breathtaking cloudscapes viewed above Japan’s mountain ranges, capturing a sense of elevation, calm, and movement. Its richly textured blue dial evokes layers of drifting clouds against the sky, brought to life through Grand Seiko’s exceptional dial craftsmanship and attention to detail.

Powering the watch is the Hi-Beat Caliber 9S86, an in-house automatic movement operating at 36,000 vibrations per hour and equipped with a true GMT function for tracking a second time zone independently. The bold 44mm stainless steel case delivers strong wrist presence, while the blue and white rotating bezel adds both visual contrast and practical functionality. Zaratsu polishing ensures crisp lines and distortion-free surfaces throughout.

This example is in very good condition and comes with its original box. A standout Grand Seiko GMT that blends technical performance with striking, nature-inspired design.
