Grand Seikoさんのインスタグラム写真 - (Grand SeikoInstagram)「Why craftsmanship leads to precision Every 9S movement is made at the Grand Seiko mechanical watch facility in Shizukuishi in northern Japan. Within the same facility is a recently opened new studio where the movements and then complete watches are assembled and adjusted by hand by a team of craftsmen and women who have honed their craft to such an extent that they can adjust parts by hand to tolerances of one hundredth of a millimeter. Their work is all about precision. Caliber 9S85 is a 36000 vph high beat movement that is adjusted to +5 to -3 seconds per day. #グランドセイコー #grandseiko #sbgj201 #gs #9s86 #watch #腕時計 #craftsmanship #madeinjapan #heritagecollection #thenatureoftime #watchfan」10月6日 18時57分
