Historical context
Quartz Revolution (1969 – 1990)
Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.
Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

Atlas type guide
Quartz, digital and electronic watches
Electronic watches arrived in three steps. The Hamilton Electric 500 (1957) was the first battery-powered wristwatch, still with a balance; Bulova's Accutron (1960) used a tuning fork. On 25 December 1969 Seiko released the Astron 35SQ, the first quartz wristwatch, closely followed by the Swiss Beta 21 group. In 1972 Hamilton's Pulsar introduced the LED digital watch, and LCD displays soon made digital watches cheap.
The 'Quartz Crisis' that followed devastated the Swiss mechanical industry, which lost two-thirds of its workforce between 1970 and 1984 before recovering with the Swatch (1983) and the luxury mechanical revival. Solar, radio-controlled, kinetic and connected smartwatches continue the electronic line.
What to look for
- Battery hatch in the case back and calibre markings with 'Quartz' or a crystal frequency.
- Display technology: LED (red, push-button) versus LCD (always-on).
- Tuning-fork hum and a smoothly sweeping seconds hand on Accutrons.
- Model and reference numbers, often printed on the back.
Dating clues
- Electric balance watches: from 1957.
- Tuning-fork watches: 1960–c. 1977.
- Quartz analogue: from December 1969; LED digital: 1972–c. 1978; LCD from 1973.
