A Spring Drive GMT inspired by the Hotaka Peaks

The Grand Seiko SBGE305 “Morning Glow of Hotaka Peaks” commemorates the 20th anniversary of 9R Spring Drive. Evoking the rugged beauty of the Hotaka Peaks, the black ceramic bezel mirrors the steep rock surface, while the red dial captures the essence of summer's sunrise.

The stainless steel case, with a diameter of 40.5mm, thickness of 14.7mm, and a length of 48.7mm, exudes a perfect balance of strength and sophistication, ensuring a comfortable fit on the wrist.

Underneath the robust exterior lies Caliber 9R66, a Spring Drive movement with 30 jewels and a remarkable accuracy of ±1 second per day or ±15 seconds per month on average. The automatic power source provides approximately 72 hours of duration, ensuring reliability.
