The 44GS, the watch released in 1967 that was the first to fully embody the Grand Seiko Style, has evolved into a modern model with contemporary practicality. The SBGW297 is a manually wound mechanical model that features the smallest case diameter of the 44GS lineup at 36.5 mm. The watch is designed for ease of wear with its moderate size and comfortable bracelet. The thin, compact case and multifaceted, diamond-cut indexes sparkle beautifully and harmonize with the refined white dial, enhancing legibility. Protecting the dial, a box glass imparts a warmth to the design, further connecting the watch to its mid-century predecessor.
