Record summary
Held and catalogued by Science Museum Group, London (object number 2012-2), this is an escapement model by Daniels, George, made in Switzerland, Switzerland, dated 1999. The Atlas places it in the Mechanical Renaissance period (1990 – 2010) of its Movements & Components collection. The record is illustrated with 4 photographs.
Assembled from the source record's structured fields. Dates and attributions are given as the source states them; where a field is missing the Atlas leaves it blank rather than estimating.

Historical context
Mechanical Renaissance (1990 – 2010)
Mechanical watches return as cultural objects; independent watchmaking flourishes.
New mechanical calibres, co-axial and other escapements, and silicon components renewed mechanical movement design.

Escapements and escapement models
The escapement is the heart of every mechanical clock and watch: it releases the gear train one tooth at a time and gives small impulses to the oscillator (pendulum or balance) to keep it swinging. The verge (thirteenth century), anchor (c. 1670), deadbeat (c. 1715), cylinder (1720s), lever (c. 1755), detent (1780s) and co-axial (1970s) escapements each solved problems of friction, recoil and isochronism in different ways.
Large demonstration models of escapements were made for teaching in horological schools, for patent applications and for exhibitions. They are valuable because they make visible, at large scale, the minute interactions that take place in a watch many times per second.
What to look for
- The shape of the escape wheel teeth: crown wheel (verge), pointed (anchor), club-toothed (Swiss lever), ratchet (English lever), or two-tiered (co-axial).
- Pallets: flags on an arbor (verge), anchor-shaped, jewelled lever fork, or a detent spring.
- Whether impulse is given directly, through a lever, or in one direction only (detent).
- Teaching models usually carry the name of a school or demonstrator.
Dating clues
- Verge: c. 1275–1850.
- Anchor and deadbeat for clocks: after c. 1670 and c. 1715.
- Club-tooth Swiss lever: standard after c. 1880; co-axial in series from 1999.
