Grand Seiko Heritage SBGP013

Heritage Collection Quartz 40mm with new Caliber 9F85 The 9F Quartz Model of the Heritage Collection, which has been developed in pursuit of perfection, has been upgraded with the new 9F85 caliber. Caliber 9F85 has a time difference adjustment function that allows the hour hand to be adjusted without stopping the seconds hand and thus preserving its high precision when the wearer changes time zones. The case utilizes perfect mirror-finished surfaces created using Zaratsu polishing, and combines beautiful and shining mirror-finished and hairline-finished surfaces for three-dimensionality. Enlarged glass size makes the bezel thinner, and that gives a sharp and refined impression, and the dial looks more spacious.
