Grand Seiko Heritage Collection Caliber 9S 25th Anniversary Limited Editions: SBGH311 & SBGR325
Created by Grand Seiko lead designer Nobuhiro Kosugi and his team, the 1998 watch echoed outwardly the uniqueness, the precision, and the beauty of the new automatic movement inside. And yet there was a clear connection to the qualities that had underpinned Grand Seiko watchmaking from its earliest days. Impressive yet understated, Kosugi’s watch was suited to everyday wear even as its case and dial played with light. This melding of beauty and understatement, of excellence without pretension, dovetailed with Grand Seiko’s long-held aspiration to be the best possible practical watch. Twenty-five years on, this emblematic case design continues to inspire Grand Seiko, much as the 9S movement inside it.
