To celebrate the 20th anniversary of the 9S caliber, the Grand Seiko team has designed an 18k gold timepiece that pays homage to the high precision 9S caliber. A new interpretation of the most widely admired Grand Seiko design; created by Nobuhiro Kosugi, the designer of the first 9S watch. The timepiece is designed with an18k gold case and the dial design incorporates a special mark with alternating GS initials in a delicate mosaic that radiates out from the center of the dial in a geometric pattern. The 9S85 is adjusted to the Grand Seiko Special standard with a precision rate of +4 to -2 seconds per day; the oscillating weight carries the Grand Seiko lion emblem in 18k gold as a symbol of the enhanced accuracy.
