The 60th anniversary is also celebrated with a new quartz movement. 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. This new caliber makes its debut in two 60th anniversary designs. The first has a version of Caliber 9F85 that is specially adjusted to a level of accuracy of ±5 seconds a year. This high precision is marked by the five pointed star at the six o’clock position. The dial, too, has a unique marking with a 2020 pattern, reminding the wearer of this special year. The case design is modern in its execution. Its bezel is thin which allows the dial to be wider and therefore more legible. The case side has a sharp curve so that more light reflects off it and adds to the “sparkle of quality” that is an essential part of the Grand Seiko Style.
