Today we often associate quartz watches with affordable, everyday timekeeping. But when Seiko unveiled the Quartz Astron 35SQ on December 25, 1969, quartz represented the absolute cutting edge of watchmaking technology. The world’s first commercially marketed quartz wristwatch arrived in an 18-karat yellow-gold case with an astonishing price of ¥450,000—approximately the cost of a popular Japanese automobile at the time.

And buyers weren’t simply paying for gold. Inside was technology that seemed almost futuristic in 1969. The Astron’s quartz oscillator vibrated at 8,192 Hz, while its innovative electronic system drove an open-type stepping motor. The result was accuracy of approximately ±0.2 seconds per day and ±5 seconds per month—a dramatic improvement over the mechanical wristwatches of its era. Seiko describes the Astron as offering roughly 100 times the accuracy of a standard mechanical watch.
What began as extremely expensive technology rapidly transformed during the 1970s. Seiko moved toward mass production, quartz technology spread throughout the industry, and increasingly affordable electronic watches began challenging the dominance of traditional mechanical watchmaking. By 1982, quartz watches represented more than half of worldwide watch production.
That makes the original Astron wonderfully ironic from today’s perspective. Quartz didn’t begin as the cheap alternative to mechanical watches—it began as technological luxury. The Astron was a gold-cased demonstration of what the future of timekeeping could achieve, and that future eventually became inexpensive enough to put astonishing accuracy on almost anyone’s wrist.

Seiko later opened key quartz patents, helping its approach become an industry standard. The company even advertised its confidence in the technology with a remarkably prophetic idea: “Someday all watches will be made this way.”
