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 SBGR315 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 an ergonomic design. The light silver sunray dial pairs perfectly with the strong three-dimensional indexes and 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.
