Grand Seikoさんのインスタグラム写真 - (Grand SeikoInstagram)「Time, travel and precision This GMT watch offers the international traveler the convenience of being able to change time zones without impairing the one second per day precision of the Spring Drive movement. The rotating bezel has 24-hour markers which, when used in conjunction with the GMT hand, allow the watch to indicate three different time zones at the same time, making the watch perfect for those whose lives are international. #グランドセイコー #grandseiko #sbge201 #gs #9r66 #watch #腕時計 #craftsmanship #madeinjapan #sportcollection #thenatureoftime #watchfan」10月24日 21時25分
