The Grand Seiko Style in a 42mm case

Measuring 42mm across, SBGR309 is a larger take on a classic Grand Seiko design. The case embodies the contemporary Grand Seiko Style with its pleasing blend of hairline and mirror-polish finishing and ergonomic curves. The dark dial has faceted indexes, a color-matched date window at 3 o’clock, and robust hands that have become emblematic of Grand Seiko’s distinct aesthetic. The dial is highly legible, which is a key tenet of the brand. Paired with a three-link bracelet, SBGR309 is a highly versatile option from the Heritage Collection.
