Caliber 9S 20th Anniversary Limited Editions
Hi-Beat 36000 Special

The gold version’s 10-beat movement Caliber 9S85 operates at the higher-precision “Special” standard of accuracy. First established in 1998, the GS Standard is even more precise than the most widely recognized global standard. However, the Grand Seiko Special Standard is higher still. Because it takes an extremely skilled watchmaker many years to reach this standard of accuracy, the number of watches that can be produced each year is limited.

This version is adjusted to the Grand Seiko Special standard and delivers a precision rate of +4 to -2 seconds per day.
