The World’s First Quartz Wristwatch: Seiko Astron (1969)

The first battery-powered quartz wristwatch was invented by Seiko, a Japanese watch company. The breakthrough model, called the Seiko Quartz Astron 35SQ, was released on December 25, 1969.

🔧 Inventor and Development Team

The Seiko Quartz Astron was developed by a team of engineers at Suwa Seikosha, a division of Seiko. The project was led by Dr. Tsuneya Nakamura and his team, who worked throughout the 1960s to miniaturize quartz technology for wristwatches.

🔋 How It Worked

Unlike mechanical watches, the Astron used a quartz crystal oscillator powered by a small battery. The vibrations of the quartz crystal (32,768 times per second) regulated the timekeeping mechanism, making the watch much more accurate than mechanical counterparts.

⏱️ Significance

• Accuracy: ±5 seconds per month, a huge leap over mechanical watches.
• Revolution: It started the Quartz Revolution, or “Quartz Crisis,” which deeply impacted the Swiss mechanical watch industry.
• Innovation: Seiko’s achievement showed the world that Japan could lead in high-tech innovation.
