Grand Seikoさんのインスタグラム写真 - (Grand SeikoInstagram)「The GMT hand as a sign of good fortune All over the world, black and red combine in a harmony that is very evocative in many ways but, in Japan, they also have a significance that dates back to the eighth century. When someone was embarking on a journey, people would strike a flint against iron to produce sparks and these red sparks were thought to bring the traveller good fortune. Still today, this tradition of the Kiribi ceremony endures. The GMT hand on #SBGE201 evokes the sparks that are struck to bring good luck to those who explore the world. #thenatureoftime」1月8日 18時08分
