Historical context
Quartz Revolution (1969 – 1990)
Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.
Quartz movements and digital displays made accurate clocks cheap and ubiquitous after the early 1970s. LED and LCD clocks, clock radios and radio-controlled clocks appeared, while traditional mechanical clockmaking contracted sharply in Germany, France and Britain.

Atlas type guide
Domestic clocks
A clock combines four systems: a source of power (falling weight, coiled spring, or later electricity), a gear train that divides time, an escapement and oscillator that regulate it (foliot, pendulum or balance), and an indicating system of dial and hands or a bell. Its history runs from the large iron weight-driven clocks of the late thirteenth century to Renaissance spring-driven table clocks, the pendulum revolution of 1656, the factory clocks of the nineteenth century and electric and quartz clocks of the twentieth.
Domestic clocks also reflect regional furniture and decorative traditions — English longcase and bracket clocks, French pendules, Viennese regulators, Black Forest and American shelf clocks — and therefore record changing tastes as much as technical progress.
What to look for
- How the clock is powered: weights, spring barrel, fusee, electric coil.
- The oscillator: foliot, short pendulum, long seconds pendulum or balance.
- Whether it strikes: hour only (count wheel) or hours and quarters (rack striking).
- The maker or retailer's name on dial and movement, and any factory trademarks.
- Signs of alteration — replaced dials, converted escapements, 'married' cases.
Dating clues
- Before 1656 clocks used foliots or balances; after, most domestic clocks have pendulums.
- Anchor escapements spread after c. 1670; minute hands became common at the same time.
- Factory production in America and Germany transformed prices after c. 1840.
