Grand Seiko 9S66

9S66 description Caliber 9S66 has all the performance of the most standard automatic movement of the 9S mechanical models — Caliber 9S65 — but comes with the addition of the GMT function. Pulling the crown out by one notch enables the hour hand to be adjusted without stopping the second hand so that the highly accurate timekeeping delivered by the Hi-Beat 36000 is not lost. The watch is the embodiment of the Grand Seiko pursuit of high accuracy, maintaining exceptional precision in both the essential time display and the GMT function.
