The Grand Seiko SBGM257G delivers refined sophistication and travel-ready functionality in an elegantly balanced mechanical watch. Housed in a 39.5 mm stainless steel case with a comfortable 46.9 mm lug-to-lug span and well-proportioned thickness, its polished surfaces highlight masterful finishing. The dial features a clean design with a 24-hour GMT hand that allows tracking of a second time zone. A date window and subtle dial textures complete the classic Grand Seiko look, making this watch ideal for both global travelers and daily wearers seeking understated luxury.
At its heart is the in-house Caliber 9S66 automatic movement, renowned for reliability and mechanical excellence. The movement offers a generous 72-hour power reserve, manual winding support and accurate timekeeping. The sapphire crystal with inner anti-reflective coating ensures clarity, while the screw-down crown and solid case back provide durability. Whether used for business travel or elegant evenings, the SBGM257G combines heritage craftsmanship, precise engineering and refined styling in a timeless package.
