Calibre 9R66:
In 2006, just two years after the completion of Calibre 9R65, Grand Seiko's first 9R Spring Drive movement with GMT function, the Calibre 9R66, was unveiled.
"GMT" stands for Greenwich Mean Time, and uses a 24-hour hand (GMT hand) as the fourth hand on the watch dial in addition to the hour, minute and second hands.
