The Grand Seiko SBGM253G GMT blends classic style with modern precision. Its standout feature is the sky-blue dial, accented by a sleek 24-hour GMT hand, and paired with a rich brown leather strap for a refined finish.
At its core is the Caliber 9S66 automatic movement, known for its 72-hour power reserve and dependable accuracy — around +5 to -3 seconds/day when static, and +10 to -1 seconds/day in daily use. Travelers will appreciate the dual-time display, making it easy to track more than one time zone.
Flip it over, and you’ll find an exhibition case back with the signature lion emblem, giving a view of its fine mechanics — including the advanced hairspring and MEMS-developed escapement.
The 39.5mm stainless-steel case is protected by a box-shaped sapphire crystal with anti-reflective coating, ensuring clear visibility. A three-fold clasp with push-button release keeps the leather strap secure and comfortable throughout the day.
