  • Catalogue Essay

    Based on the iconic Calibre 4400, this airy construction exalts the art of openworking, evoking the European railway stations, symbols of the golden age of the industrial revolution.
    Openworking is a demanding art, since it involves hollowing out the mechanical parts, while being careful not to impair the running of the watch.
    It took hundreds of hours to achieve the perfect balance between airy aesthetic and optimal functionality from conceptualisation to assembling.

    To beautify this Calibre 4400SQ, the master-engraver technique is reinvented to resemble that of the sculptor, revealing fascinating light effects conveyed through a three-dimensional architecture.
    Inspired by the vaults of railway stations, he has meticulously created delicate arches on the calibre. Amid a clever interlacing pattern of interior angles that only the human hand is capable of creating, the polished zones catch the light and contrast with the matt finish of the hand-drawn surfaces.

    The Mécaniques Ajourées timepiece is ennobled by Grand Feu enamelling. Brilliantly performed, the vivid beauty of red pays tribute to the Principality of Monaco.

    Besides the red enamel ring, the Roman numerals ring is openworked with “ONLY WATCH” and the caseback is engraved with “2015” and “N°1/1”, making it a unique piece.
