    One can always trust Maximilian Büsser and his team at MB&F to come out with creative ways to reinterpret and even better one of the most traditional of complications: the perpetual calendar.

    Introduced in 2015, the MB&F Legacy Machine Perpetual is a technical marvel that offers significant improvements to eliminate the fragile drawbacks and gear jams tied to the conventional perpetual calendar mechanism. A mechanism device by Stephen McDonnell, an Irish independent watchmaker, an open-worked design by Eric Giroud result in an extraordinary cutting edge timepiece…inside and out.

    Awarded the Best Calendar Watch in GPHG 2016, the three-dimensional architecture of the model exhibits a revolutionary in-house mechanism featuring 581 components. The mechanical processor uses a default 28-day months—as opposed to the traditional use of 31 days—and adds extra days as required without “skipping over” redundant days, resulting a fool-proof system that auto protects itself from incorrect manipulation.
    The amazing movement, is not only impressively complex but beautifully hand finished, the dial side showing the wide array of gears, clicks, pinions and bridges with a 14mm flying balance wheel suspended above. The back side is also beautifully hand finished with perfectly aligned Geneva waves with interior and exterior polished angles.

    Other than the calendar functions, a power reserve display and a leap year indication are playfully presented on retrograde scales.

    The present Legacy Machine Perpetual Calendar is number 2 of a limited edition of only 25 pieces in pink gold, making this incredibly rare and collectible timepiece from the brand. A visually arresting design and a true spectacle to admire, the present example preserved in the excellent overall condition is complete with its full set of accessories.

    Please note that MB&F generously offers a complementary servicing of the watch to the winning bidder within a period of 6 months after the sale.
