Grand Seikoさんのインスタグラム写真 - (Grand SeikoInstagram)「A seconds hand that moves in glide motion Because all the motion within a Spring Drive movement is in one direction, the seconds hand moves in perfect glide motion. Just like time itself, the seconds hand moves continuously and silently with no tick or shudder. Spring Drive expresses the natural flow of time in a uniquely precise and beautiful way. In this GMT Spring Drive watch with caliber 9R66, the hour hand can be adjusted independently to show a second time zone while the GMT hand will keep showing your home time. #グランドセイコー #grandseiko #sbge201 #gs #9r66 #watch #腕時計 #craftsmanship #madeinjapan #sportcollection #thenatureoftime #watchfan」10月14日 19時23分
