Clerkenwell and the London Trade

Clerkenwell, in central London, was for roughly two and a half centuries the organisational heart of the English watch trade: a dense concentration, within a few streets around St John's Square and Clerkenwell Green, of specialist small workshops — movement finishers, escapement makers, dial enamellers, case makers, jewellers, gilders and materials dealers — whose coordinated outwork produced most of the watches signed by London retailers and by makers across the wider English trade.

This 'manufactory' system, dispersed across many independently owned workshops rather than concentrated in a single factory, allowed considerable flexibility and high-grade bespoke work (serving figures such as Thomas Tompion's and George Graham's successors, and the later chronometer makers) but resisted the mechanisation and rationalisation that American firms adopted from the 1850s, leaving Clerkenwell's output comparatively labour-intensive and costly by the later nineteenth century.

Clerkenwell's watch trade declined steeply from the 1880s onward under American and Swiss competition, and by the early twentieth century most of its specialist workshops had closed or converted to other trades; the Clerkenwell and Islington Guildhall Library's horological collections, together with the Clockmakers' Museum (historically associated with the Worshipful Company of Clockmakers), remain principal repositories documenting the district's trade.
