French Carriage Clock
Partially verifiedThe portable clock of the nineteenth century: a spring-driven movement with a platform escapement in a glazed brass case with a handle, made for travelling and sold in enormous variety.
Overview
Carriage clocks solve a specific problem: a pendulum cannot travel. Substituting a balance-and-lever platform escapement makes a clock that keeps running when moved, at the cost of the pendulum's stability.
The French trade produced them in vast numbers and in every grade, from plain striking clocks to grande sonnerie repeaters with enamel panels.
History
The type descends from the earlier pendule d'officier and from Breguet's portable clocks, and was industrialised by the French provincial trade.
Much production was supplied to retailers who signed the dial; the signature is usually a seller, not the maker.
Design
The removable platform allows the escapement to be regulated and serviced as a unit.
Case styles — gorge, oval, Anglaise, cannelée and others — are a recognised typology used for description and dating.
Movement
Movement backplates often carry maker or trade stamps and serial numbers; these are the main manufacturing evidence.
Platform escapements sit horizontally under a cock at the top of the movement; replaced platforms are extremely common and significantly affect originality.
Striking and repeating work adds a hammer train and, in grande sonnerie, a substantially more complex mechanism.
Case
Bevelled glasses are frequently replaced; original glass shows period characteristics and is worth preserving.
Regilding destroys original finish and patina; it is one of the most common over-restorations in this field.
Dial and hands
Enamel dials chip at the winding holes and at the edges; replaced dials are common in restored clocks.
Subsidiary alarm dials are original to alarm models only — an added alarm dial is a marriage.
Technical specifications
| Movement | Small plated spring-driven movement with a platform escapement |
|---|---|
| Movement type | Spring-driven, plated, with a horizontal platform escapement |
| Escapement | Lever escapement on a removable platform; cylinder in cheaper work |
| Jewels | Platform jewelled in better work |
| Winding and setting | Key-wind from the back |
| Size | Commonly 10–20 cm high excluding the handle |
| Power reserve | Typically about eight days in better work; shorter in simpler movements |
| Frequency | Platform escapement rate varies by movement |
| Accuracy | A good platform-escapement carriage clock keeps respectable domestic time; it is not a regulator |
| Complications | Hour and half-hour striking, repeat, alarm, grande sonnerie and calendar in elaborate examples |
| Escapement | Platform lever (cylinder in cheaper work) |
| Power | Spring-driven, key-wound from the rear |
| Case | Glazed brass with carrying handle |
| Typical duration | About eight days in better movements |
Identification
- Remove the back and photograph the backplate stamps and serial number before doing anything else.
- Check whether the platform matches the movement's period and whether the escapement is lever or cylinder.
- Case typology (gorge, Anglaise, oval and so on) plus movement stamps give a defensible description.
Variations
- Timepiece only, striking, repeating, alarm, grande sonnerie and calendar variants.
- Enamel, porcelain, engraved and champlevé decorated cases.
- Miniature carriage clocks and giant presentation examples.
Serial numbers and dating
- Backplate numbers relate to trade production and can sometimes be grouped by maker, but published concordances are incomplete.
- Treat a date derived from a backplate number as an estimate unless a documented maker's record supports it.
Known examples and institutional holdings
- Decorative arts and horological museum collections hold documented examples across the grade range, including elaborate sonnerie clocks.
Collecting
- Originality of the platform, the glasses, the gilding and the dial are the four decisive questions.
- Complicated examples attract the most attention and therefore the most restoration and marriage.
Restoration and conservation
- Resist regilding; conserve original finish. Replaced platforms should be disclosed, not blended in.
- Movement work — cleaning, lubrication, mainspring replacement, pivot or jewel work — belongs with a qualified watchmaker. Conserve original parts; do not refinish dials or polish cases to remove honest wear.
