To celebrate the 20th anniversary of the 9S caliber, the Grand Seiko team has designed a stainless steel timepiece that pays homage to the high precision 9S caliber. A new interpretation of the most widely admired Grand Seiko created by Nobuhiro Kosugi, the designer of the first 9S watch. The timepiece is designed with a stainless steel 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 standard with a precision rate of +5 to -3 seconds per day. The stainless steel design also has a special oscillating weight made of titanium and tungsten with the titanium surface colored blue by an anodic oxidation process.
