The Grand Seiko Boutique designed based on the Grand Seiko blue as brand color offers a rich lineup of timepieces. Among them, this limited edition model is only available at the Grand Seiko Boutique.
The blue dial—which features a 'Mount Iwate pattern' showing the ridgelines of the magnificent mountain visible from the Shizukuishi Watch Studio where all Grand Seiko mechanical timepieces are made— expresses the beauty of winter mountain scenery emerging faintly through moonlight reflected on snow.
The exterior design is a modern take on the stunning 'Grand Seiko Style'—the embodiment of the Grand Seiko design philosophy which was first established for the 44GS in 1967—and features a distortion-free, wide mirror surface throughout.

The words “Grand Seiko Boutique Limited Edition” are displayed proudly on the sapphire glass case back, which also is marked with the Grand Seiko lion emblem.
This high-specification movement delivers the same accuracy (+5 to -3 seconds a day) and the same power reserve (55 hours) as the core Caliber 9S85, while also offering the GMT function that the international traveler needs to ensure that the accuracy of the time shown is not compromised when the time zone is changed. The GMT hand shows the time in the home time zone.
Pulling the crown out by one notch enables the hour hand to be adjusted without stopping the second hand so that the highly accurate timekeeping delivered by the Hi-Beat 36000 is not lost. Caliber 9S86 is the embodiment of the Grand Seiko ideal of high accuracy, maintaining exceptional precision in both the essential time display and the GMT function.
