Paired with the release of these movements in 1998 were newly designed watches that matched their uniqueness, precision, and overall sense of beauty. Lead designer Nobuhiro Kosugi sought to create the “best possible practical watch,” and in his efforts, he and his team established a new design based on the Grand Seiko Style, cementing an aesthetic that holds strong to this very day.
Today, Grand Seiko celebrates the 25th anniversary of the first Caliber 9S with two special models, each with the same emblematic case design that first housed the 9S movement in 1998. Measuring 37mm in diameter and 13.3mm in thickness and paired with a stainless steel bracelet with a three-fold clasp, these two commemorative timepieces embody Kosugi’s original design while also honoring the beauty of Shizukuishi.
SBGH311 is the first of these two celebratory timepieces. With its distinct texture and silver color, the dial of SBGH311 evokes the sea of clouds that cover Mt. Iwate at daybreak. This phenomenon occurs when the air is so still and humid that dense clouds overlap and create a mesmerizing silvery-white sea. Electroforming was used to create this entirely new dial pattern, giving it a uniquely mottled effect never before seen from Grand Seiko. The diamond-cut hour and minute hands, tempered blue seconds hand, and indexes offer beauty and legibility, a key tenet of Grand Seiko’s design language. A gold color Grand Seiko logo offers a splash of warmth against the cooler backdrop.
SBGH311 is the first global release to bring together a Hi-Beat movement and the original 37mm case. Visible through the sapphire crystal case back is the Hi-Beat 36000 automatic mechanical Caliber 9S85. This excellent movement is hand-assembled by the skilled craftsmen and women of Grand Seiko Studio Shizukuishi. It features an accuracy rating of +5 / -3 seconds per day with a 55-hour power reserve. Additionally, the oscillating weight has undergone an anodic oxidation treatment, giving it a distinct and vibrant blue hue that suggests the deep-blue sky above the sea of clouds. A Grand Seiko emblem is inset into the oscillating weight.
The second commemorative model, SBGR325, features a dynamic blue dial with a delicate sunray finish, expressing the clear sky that can be seen from atop Mt. Iwate’s peak. This striking finish reflects light from all angles, and it pairs beautifully with the diamond-cut hands and indexes, tempered blue seconds hand, and gold color Grand Seiko logo.
SBGR325 is powered by Grand Seiko Caliber 9S65, an automatic movement with a mean daily rate of +5 / -3 seconds per day and a 3-day power reserve. This movement also features an inset emblem in a commemorative oscillating weight rendered in Grand Seiko blue via an anodic oxidation treatment.
SBGH311 is a limited edition of 1,200 and will be available at Grand Seiko Boutiques and select retail partners in February 2023 for 262,100 baht SBGR325 will be available as a limited edition of 1,200 at Grand Seiko Boutiques and select retail partners in April 2023 for 211,100 baht.
