Catalogue Essay
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 designed by Stephen McDonnell, a genius Irish independent watchmaker, combined with 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 in a fool-proof system that auto protects itself from incorrect manipulation.
The movement is not only impressively complex but beautifully hand finished. The dial side shows the wide array of finely hand-finished 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. The dial displaying the hours and minutes, as well as the subdial rings, are all crafted in glossy white lacquer – an old school touch.
In 2023, MB&F introduced the present iteration of the Legacy Machine Perpetual Calendar in stainless steel with a subtle salmon-hued dial plate to much adoration by collectors. It remains in production but extremely difficult to receive an allocation. This highly coveted example is offered by its original owner in virtually brand new condition with all of its original accessories.
