Measuring 42mm across, SBGR307 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 light sunray dial has large faceted indexes, a date widow at 3 o’clock, and robust hands that have become emblematic of Grand Seiko’s distinct aesthetic. A tempered-blue second hand adds a splash of color and aids in legibility, which is a key tenet of the brand. Paired with a three-link bracelet, SBGR307 is a highly versatile option from the Heritage Collection.
