Grand Seiko Heritage SBGR317

The Grand Seiko Style in a 40mm case

Royal Jewelers is an authorized Grand Seiko dealer in the Boston area and offers the Grand Seiko SBGR317 Heritage with Grand Seiko's 5 year warranty.

With its accommodating 40mm diameter, this model combines presence and wearability with ease. The case embodies the contemporary Grand Seiko Style with its pleasing blend of hairline and mirror-polish finishing on top of ergonomic geometry. The deep black dial gives the watch a more compact look, and the strong three-dimensional indexes pair perfectly with the bold handset, resulting in a highly legible watch even at a glance. Inside is Caliber 9S65, an automatic movement with manual winding capacity rated to +5 to -3 seconds a day. It features a power reserve of 72 hours, made possible through proprietary hairspring technology and an escapement made via MEMS.
