Grand Seiko 56GS 5645-7010 Sunburst Dial

Introduction:

56GS was the last generation of vintage Grand Seiko. Right after Seiko issued the 61GS, there was a need to build the ultimate daily watch that could be used for decades, so there were some majors changes. In order to improve robustness and stability, the frequency of the movement was adjusted to 28800bph from 61GS's 36000bph. The movement was also redesigned to be thin and compact, making 56GS the slimmest automatic Grand Seiko at that time. This watch here has a rare silver sunburst dial, as opposed to plain white dial found on most of the 56GS.
