SBGJ235 features Grand Seiko's modern 44GS design, a contemporary take on a watch that first launched in 1967 and formed the cornerstone of the Grand Seiko Style. The modern interpretation of the 44GS is one of Grand Seiko's best known designs, and it remains a pillar of the brand's catalog today.
The dynamic blue dial features Grand Seiko's iconic "Mt. Iwate" texture, a pattern inspired by the many-ridged contours of Mt. Iwate, which is visible through the windows of Studio Shizukuishi where Grand Seiko mechanical watches are made. The dial expresses the beauty of the winter mountain scenery emerging faintly through moonlight reflected on snow. Multi-faceted hands and hour indexes give the dial depth and dimensionality and are emblematic of Grand Seiko design.
Powering the watch is the Hi-Beat Caliber 9S86, which runs at 36,000 bph, delivers an accuracy of +5 to -3 seconds a day, and offers 55 hours of power reserve. A GMT function allows the user to track an additional time zone, making SBGJ235 an excellent timepiece for frequent travelers. The words "Grand Seiko Boutique Limited Edition" are displayed proudly on the sapphire glass case back, which is marked with the Grand Seiko lion emblem.
