As the name suggests, the Manufactures des Montres & Chronographes Pierce S.A., established in 1883 by Leon Levy and his brothers in Moutier, heart of Switzerland watchmakers, set its sights high.
At that time chronographs were not a widespread category of watches. The idea The idea was presumably the right one because the company was soon employing 1500 people. From the early twenties massive overproduction and the resulting price war triggered a severe crisis in the Swiss watch industry. In the end Pierce found itself without movement suppliers because of official and industry counter-measures. The Bienne company was therefore obliged to develop its own movement calibers from the 1930s. Among these were the 13-ligne chronograph calibers 130 and 134 with column wheel and a vertical friction clutch. Other interesting collector’s watches from Pierce include the “DuoFon” alarm wristwatch with two volumes of sound for the alarm function, and the “Correctomatic”, where the rate could be adjusted by external pushpieces.
