Grand Seikoさんのインスタグラム写真 - (Grand SeikoInstagram)「Caliber 9F, which was developed to create the ultimate quartz watch, now features the GMT function. This Grand Seiko Sport Collection allows you to fully enjoy the Caliber9F86 in a genuinely sporty design with the sophisticated thinness that is unique to quartz watches. The contrast created by the striking GMT hand and the upper and lower two-toned dial rings helps you intuitively tell whether the time indicated by the GMT hand is day or night. Ref.
