Lot Essay

Cedric Jagger, Paul Philip Barraud, 1968 does not record any Barraud chronometer fitted with a pivoted detent the construction of which comprises a pivoted arbor at the outer end mounted between the underside of the top-plate and an underslung potance; the lateral motion of the detent is controlled by a pressure spring mounted under the top-plate - not by a spiral spring as fitted to continental format pivoted detents.
The casemaker is George & John Carpenter, 12 King Street, Clerkenwell whose Mark was entered 16 October 1804.
