In 1960, a specialized group of craftsmen set out to design and create an in-house movement for Seiko that resulted in the Calibre 3180.  This movement became the foundation for a new line of Seiko timepieces that would become the Grand Seiko.  The pursuit was to create the “ideal watch” in every way, from precision, legibility, and beauty.  Having conquered the movement, the designers next set out to create a case and finish that modeled their idea of beauty, including zaratsu polishing.  This polishing process produces a mirror-like quality to the case finish and the hands and indices that give the Grand Seiko its distinct appearance.

The Grand Seiko Heritage Quartz SBGP001 features a 40mm stainless steel case with zaratsu polishing, a fixed polished bezel, and a sapphire crystal.  The dial features a silken texture with a sunray pattern, multi-faceted zaratsu polished hour markers, hour and minute hands with diamond-cut edges, a blued seconds hand, and a date window at the 3 o’clock position.  Powered by the quartz Caliber 9F85 movement, the SBGP001 has a time difference adjustment function that allows the hour hand to be adjusted without stopping the seconds hand, thus preserving its high precision when the wearer changes time zones.

This Grand Seiko Heritage Quartz SBGP001 includes an aftermarket brown leather strap with a stainless steel buckle.
