Automatic Date Stainless Steel / Black / Bracelet

Grand Seiko's Mechanical collection houses the brand's traditional hand-wound and automatic movements, continuing a pursuit of precision that began in 1960 when the first Grand Seiko was created to rival the best Swiss chronometers. The Hi-Beat movements operating at 36,000 vibrations per hour deliver a level of accuracy and smoothness that few manufacturers attempt, while the Zaratsu polishing technique — a method of achieving distortion-free mirror surfaces learned from sword-polishing traditions — gives every case and bracelet a quality of finish that is immediately apparent in person. The Mechanical family represents Grand Seiko's argument that Japanese watchmaking can match and exceed the standards set by the Swiss industry.

The Grand Seiko SBGR309 was introduced with the re-branding of Grand Seiko in 2017. This watch features a stainless steel case and a black dial. It is powered by the self-winding caliber 9S68.
