SBGA439G Heritage Spring Drive 40 mm
Description of the watch
This 40mm diameter Spring Drive model is, like all Grand Seiko models, a tribute to nature.
The changing and bewitching hue of the moonlit night sky has been captured to perfection in this midnight blue dial. Depending on the light variations of day and night, outdoors or indoors, the dial can change from a warm blue to an absolute black.
The watch is powered by the Spring Drive 9R65 caliber, hand-assembled by the skilled craftsmen of Shinshu Watch Studio. The power reserve is 72 hours when fully wound and can be checked on the indicator next to the eight o'clock index.
