A Limited-Edition Spring Drive Chronograph in the Evolution 9 Style

2022 is the 15th anniversary of Grand SeikoÕs first Spring Drive chronograph. Commemorating this milestone, SBGC249 is a limited-edition Spring Drive chronograph and the first chronograph in the Evolution 9 Collection.

SBGC249 is made from High-Intensity Titanium and measures 45.3mm in diameter, 15.8mm in thickness, and 52.6mm lug-to-lug. The bezel insert is sapphire, which makes it highly impervious to scratches. The pushers for operating the chronograph function have been redesigned, and they now sit closer to the case. A dual-curved sapphire crystal with anti-reflective coating along the inner surface covers the Cosmo Blue dial. The Evolution 9 Style hands and indexes offer immediate contrast against the inky dial, and their size makes reading the time immediately possible. Legibility is further enhanced with ample use of LumiBrite on the hands, indexes, and bezel.

SBGC249 is powered by caliber 9R96, a Spring Drive chronograph with a GMT function. It features an 18k gold medallion on the oscillating weight, and it is specially adjusted to have an accuracy rating of ±0.5 seconds per day (or ±10 seconds per month).

SBGC249 is a limited edition of 700.
