Quartz revolution.

With the arrival of the age of quartz watch, the hegemony of the watch shifted from Switzerland to Japan.
The watch of Seiko was adopted as the official timing device of the Tokyo Olympics. At that time they used electronic timing and became recognized worldwide. After that, they mass-produced quartz watches and chased the production of Swiss watches to the state of dying.
This is called "quartz crisis". (It is often referred to as the "quartz revolution" outside of Switzerland.)


水晶時計の時代の到来を契機に、時計の覇権はスイスから日本へシフトしていった。
セイコーは東京オリンピックの公式計時機器に採用された。その際に電子計時を使用し、世界的に認められるようになる。その後、クオーツ時計を量産し、スイスの時計の生産を瀕死の状態まで追い詰めた。
これを「クオーツショック」と言う。(スイス以外ではクオーツ革命として知られている。)
