The Everbright is the first regular Grand Seiko model to offer the world's highest level of corrosion resistance, not only for the case but also for the bracelet. Beautiful, modern materials are harmoniously combined with the innovative "Caliber 9SA5" movement, which was released in 2020 and will be responsible for the next generation, while the 55th anniversary "44GS" perfectly highlights the design.
 The dial of this work is inspired by the majestic Mount Iwate, which can be seen in the "Grand Seiko Studio Shizukuishi", which produces Grand Seiko mechanical models.
 The spring thaw, which has visited Mount Iwate since ancient times, signals the beginning of a new season to people. The shadow of SLGH013's graceful pattern and pale blue color, close to silver, reflect the spring thaw that comes to Mount Iwate. the expression is slightly different depending on the lighting angle.
