Historical context
Modern Mechanical Horology (1945 – 1969)
Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.
Post-war clocks combined new materials and industrial design: plastic and metal cases, battery-powered transistor movements from the late 1950s, and design classics by George Nelson, Max Bill and others. The first caesium atomic clock (1955) moved the definition of time from astronomy to physics.

Atlas type guide
Astronomical, musical and automaton clocks
Astronomical clocks display more than the hour: the positions of the sun and moon in the zodiac, the phase of the moon, the calendar, sometimes the planets and eclipses. From Richard of Wallingford's and Giovanni de' Dondi's fourteenth-century clocks to the Prague Orloj and the Strasbourg cathedral clocks, they demonstrated the order of the cosmos. Renaissance makers in Augsburg and Nuremberg built celestial globe clocks and monstrance clocks as princely treasures.
Automaton and musical clocks entertained as well as informed: figures move, birds sing, organs and carillons play tunes from pinned cylinders. The eighteenth-century trade with China ('sing-songs') and Ottoman Turkey created a market for elaborate English, Swiss and French automata.
What to look for
- Subsidiary dials for moon phase, calendar, zodiac and planetary positions.
- Celestial globes or armillary spheres turned by the movement.
- Pinned cylinders, bellows and pipes or bells for music.
- Figures on cams and levers; separate trains for automaton work.
Dating clues
- Renaissance astronomical table and globe clocks: c. 1550–1650.
- English and Swiss automaton clocks for the Chinese market: c. 1760–1820.
- Picture clocks (clockwork pictures) are mostly nineteenth century.
