Accuracy: +/- 5 Sec. Per Year (Enhanced GS Cal. 9F62)

The GS manual lists this Grand Seiko as an enhanced version of the Cal. 9F62 which keeps +/- 5 sec. per year accuracy

For comparison: a mechanical COSC certified chronometer watch only keeps −4/+6 sec. per day accuracy.

From notes on the accuracy of the watch from the manual:

"This watch is an enhanced version of the Cal.9F62 which is specifically designed to keep the annual loss/gain within 5 seconds, while the annual loss gain loss/gain of conventional - type Cal.9F62 is within 10 seconds."

Below are photos of the fine finishing of the movement and the manual quoted above:
