    Audemars Piguet History

    Our Grande Complication has as many as 648 parts, all hand-assembled at a master watchmakers workbench.


    to break the rules,
    you must first master
    them.

    The vallée de Joux. For millennia a harsh,
    unyielding environment; and since 1875 the
    home of audemars piguet, in the village of
    Le Brassus.
