  • Catalogue Essay

    Since the beginning of chronometer competitions in 1866 and 1873, for Neuchatel and Geneva respectively, manufactures such as Patek Philippe and Vacheron Constantin have been very ambitious in creating the best and most accurate movements.

    For the Geneva Astronomical Observatory contest, the manufacturers would prepare watches for their competitive trials, testing and breaking new ground on chronometry.

    The present watch, having won second prize in the Concours de l'Observatoire Astronomique, features a beautifully finished Guillaume Balance. Made of a steel and nickel alloy with anti-magnetic properties, it is unaffected by varying temperatures. It is an invention that enabled its inventor, Charles-Edouard Guillaume, to win the Nobel Prize for physics in 1920.

    According to research, the registers of the Geneva Observatory state that this watch was presented at the 1927 contest where it achieved the second prize with 771 points. It had been prepared and adjusted by the master precision adjuster F. Moudoux.
