The Grand Seiko Spring Drive GMT SBGE305 belongs to the Sport Collection and was released in 2024 as a limited edition of 1,300 pieces. Its round steel case measures 40.5 mm in diameter and 14.7 mm in thickness, with a 20 mm lug width, which makes it a practical size for daily wear as well as travel.

The dial is red with a sunburst finish and carries the nickname "Morning Glow of Hotaka Peaks". Applied indexes and Lumibrite hands support legibility in low light, while a silver GMT hand tracks a second time zone. A date window sits at 4 o'clock, and a power reserve indicator completes the layout. The bidirectional rotating bezel is black ceramic and carries a 24-hour scale.

Inside, the watch runs on the Spring Drive caliber 9R66, the movement technology particular to Grand Seiko. A sapphire crystal and a solid caseback protect the watch, and water resistance is rated at 200 m. The SBGE305 suits collectors and frequent travelers who want a steel sports watch with GMT function, produced in a limited run in 2024 and offered at a public price of 6,600.
