First debuted in 2015, the MB&F Legacy Machine Perpetual is a technical marvel and reinterpretation of a new perpetual calendar that offered 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 and a spectacular movement finished by none other than Kari Voutilainen result an extraordinary avant-garde timepiece of our times.

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. Encased in platinum featuring an electric blue dial and the brand’s signature flying balance suspended above the mechanism and can be fully appreciated under the high-dimed crystal. The back side is also beautifully hand finished with perfectly aligned Geneva waves with interior and exterior polished angles, and finessed with an elegant engraving the watchmaker’s name.

The present Legacy Machine Perpetual Calendar is numbered 8 of a limited edition of only 25 pieces, 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 fresh-to-the-market and offered by the original owner with its complete 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.
