Description: Gilt brass, slim 2/3 plate pillar-less caliber, (42mm diameter). Single-roller detached lever escapement showing distinct Swiss or French influence. Polished steel club-tooth escape and large exposed ruby pallets, roller with oval shaped jewelled pin. Compensation balance, spiral balance-spring. Perfect signed ‘Parkinson & Frodsham London’ enamelled copper dial with sunk seconds at 6. (A)
Additional Info:
This movement shows many aesthetic and mechanical parallels to the pieces made by the ‘British Watch & Clockmaking Company’. The unusual lever escapement most probably has been made by an expatriated Swiss or French watchmaker (A). Sylvain Mairet who spent several years in London working for many well known watchmakers such as Benjamin Vulliamy and the Dent firm could be considered the most probable (A).
