The Atlas places it in the Early Modern Horology period (1600 – 1750) of its Movements & Components collection. Materials and techniques recorded by the source: Brass, iron. Recorded dimensions: H. of lantern clock: 13 in. (33 cm); W. of lantern clock: 6 1/2 in. (16.5 cm). 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

Early Modern Horology (1600 – 1750)

Huygens' pendulum and balance spring transform accuracy; English makers develop the anchor and deadbeat escapements.

The pendulum, anchor escapement and balance spring transformed movement design; English makers introduced jewelled bearings (1704).

Clock and watch movements

The movement is the mechanism of a clock or watch, without its case and dial. It consists of the power source (weight or mainspring in its barrel, sometimes with a fusee), the going train of wheels and pinions, the escapement and oscillator, the motion work that drives the hands, and in many cases additional trains for striking or complications.

From the eighteenth century watch movements were increasingly produced in stages: Swiss and French ébauche makers supplied rough movements that finishers, repasseurs and retailers completed and signed. Calibre numbers — first used systematically by American and Swiss factories in the nineteenth century — make it possible to identify movements, find spare parts and date watches.

What to look for

  • Plate and bridge layout: full plate, three-quarter plate, Lépine bar calibre, bridges and cocks.
  • Jewel count and whether jewels are set in chatons or rubbed in.
  • Signatures, calibre and serial numbers on the plate or under the dial.
  • Finishing: Geneva stripes (Côtes de Genève), perlage, bevelled edges, blued screws.
  • Fusee and chain, going barrel, or electrical components.

Dating clues

  • Full-plate English movements dominate before c. 1850; three-quarter plate and Lépine calibres after.
  • Jewelled movements spread after Facio and Debaufre's patent of 1704, mainly in English work until c. 1800.
  • Calibre numbers and factory serials allow close dating for industrial production after c. 1850.
