Gold pair-cased lever escapement watch by John Leroux, London. Gold cases stamped VW (for casemaker Valentine Walker) and hallmarked for 1785 – 1786. White enamel dial signed 'Leroux London'. Central minute hand with subsidiary dials for hours and seconds. Gold hands. Details of lever escapement; all the impulse is given by the inclines on the hook-shaped teeth of the steel escape-wheel, to pointed pallets on the lever. The short lever is placed tangentially to the escape-wheel. The pallets embrace only two teeth of the escape-wheel. A jewel set in the tail of the lever moves between the adjustable banking pins. The balance staff has a cranked roller for impulse and unlocking, and a separate roller for the safety-dart. The design of this escapement provides draw. The balance is a four-arm steel wheel with timing screws and with two bi-metallic arms fixed to it, with stops to limit their outward movement. The free-sprung balance-spring is conical in shape. Full plate movement with fusee and stop lever. Movement signed 'J. Leroux Charg. Cross London'. Gold lever escapement watch by John Leroux, 1785. Clockmakers 1785
