The Grand Seiko SBGJ275G celebrates the 25th anniversary of the Caliber 9S mechanical movement with a striking GMT limited edition. Its vibrant blue dial captures the beauty of the “sea of clouds” seen at daybreak above Mt. Iwate—an awe-inspiring phenomenon where dense morning mist forms a layered sky tapestry. A rotating sapphire bezel in blue and white adds both function and visual depth, enabling the tracking of three time zones. Powering the watch is the high-frequency Caliber 9S86, beating at 36,000 vibrations per hour and hand-assembled by the skilled artisans at Grand Seiko Studio Shizukuishi.

Technical information about this watch

Grand Seiko Sport "Sea of Clouds" 44mm

A water resistance icon in the shape of a shield. On the shield is a drop of water and beside the water are two lines that looks like waves.

200M / 20 ATM water resistance

Water resistance indicates a watch's ability to withstand moisture and water. Ratings are measured in metres (M) or atmospheres (ATM). For instance, 30M (3 ATM) is suitable for light splashes, while 100M (10 ATM) and above are ideal for swimming and diving. Regular maintenance helps retain water resistance over time.

GS Calibre 9S86 Automatic winding

Caliber 9S86 builds on the core performance of Caliber 9S85, offering the same high accuracy of +5 to –3 seconds per day and a 55-hour power reserve, while adding a GMT function ideal for international travelers. The GMT hand displays home time, and the local hour hand can be adjusted independently—without stopping the seconds hand—ensuring continuous precision. This high-beat movement embodies Grand Seiko’s commitment to exceptional accuracy, whether tracking local time or a second time zone.

44mm case size

Case size, measured in millimetres (mm), impacts the watch's look and fit. Men's watches typically range from 38mm to 46mm, and women's from 26mm to 36mm. Larger cases make a bold statement, while smaller cases offer a classic look. Choosing the right size ensures comfort and style.

A power reserve icon that looks like a gauge that indicates how much power is left.

55 hours power reserve

Power reserve is the duration a watch runs on a full wind or charge. Mechanical watches usually offer 40 to 80 hours, with some extending to several days. Quartz watches, powered by batteries, last several years. Knowing the power reserve helps maintain accurate timekeeping.
