Royal Jewelers is an authorized Grand Seiko dealer in the Boston area and offers the Grand Seiko Heritage Collection SBGW323 with Grand Seiko's 5 year warranty.

The Grand Seiko Studio Shizukuishi sits in the shadow of Mt. Iwate, where the ridges of the mountain have long inspired the brand’s craftsmanship. The SBGW323 captures this connection and has a striking purple dial color paying tribute to the kiri, the official flower of Iwate Prefecture. As light moves across the surface, the depth and texture of the dial create an ever-changing visual experience.

The 44GS, first introduced in 1967, established the design principles that define Grand Seiko today. The SBGW323 refines this legacy in a mid-sized 36.5mm case, balancing heritage with modernity. Zaratsu-polished surfaces contrast with delicate hairline finishing, while the box-shaped sapphire crystal adds a vintage touch. Paired with a stainless steel bracelet, the watch also features drilled lugs and an 18mm width for effortless customization.

Assembled by hand by the artisans of the Grand Seiko Studio Shizukuishi, Caliber 9S64 is a manual-winding mechanical movement with a 72-hour power reserve and an accuracy rating of -3 to +5 seconds per day.
