Pierre Deroche calibre dubois depraz

Pour ne pas raconter n’importe quoi concernant "l’histoire" du fondateur, voilà:
Mechanics has always been in the genes of Dubois family, watchmakers as well as trailblazers for four generations. In 1937, Marcel Dépraz, the great-grandfather of Pierre Dubois, CEO of Pierre DeRoche, developped a chronograph movement that was revolutionary for its time. More than 3.5 million pieces were produced until 1970. His grandson Gérald Dubois, Pierre’s father, invented the first automatic chronograph. And, not wanting to be outdone, the present generation of Pierre Dubois and his two brothers, Jean-Philippe and Pascal, invented the concentric chronograph, a Pierre DeRoche exclusivity. These three brother are certainly not lacking in ideas. Together, they have developed the first movement in the world able to house six retrograde seconds mechanisms, a little revolution presented at Baselworld 2009. The idea grew out of a passionate discussion around the family table, proof that the "horological chromosome" of the Dubois family is transmitted from generation to generation: a promise of wonderful surprises to come! And in fact, the name Pierre DeRoche already came across Pierre Dubois’ mind when he was a child…inspired by his grandfather Reynold, who used to tell him that his Christian name meant "rock"!*
