The Legacy Machine Perpetual, the award-winning and convention-breaking perpetual calendar conceived for MB&F by Stephen McDonnell, gains a new level of liberation with the Legacy Machine Perpetual EVO.
A 44mm case in zirconium or titanium, modern metals with material properties surpassing stainless steel. A new case profile that emphasises openness and extreme clarity. A specially developed monobloc shock-absorbing system – “FlexRing” – that makes for the most robust Machine ever to emerge from MB&F. The LM Perpetual Engine, designed by Stephen McDonnell, an award-winning perpetual calendar that replaces traditional constructions with an innovative mechanical processor.
The LM Perpetual EVO was first launched in zirconium with three options of PVD/CVD dial-plate colour, including — for the first time in a high-end piece of Swiss watchmaking — atomic orange. A grade 5 titanium edition follows in 2021, with a green CVD dial plate. All editions feature a closely-fitted, integrated rubber strap for the smoothest wearing experience of any MB&F Machine ever.more pictures in press section
The revolutionary mechanical processor uses a default 28-day month and adds extra days as required. There is no "skipping over" redundant days, so the result is a fool-proof system that also auto-protects itself from incorrect manipulation.
Hours, minutes, day, date, month, and leap year can be set independently by manually pressing the redesigned, ergonomic correctors. No need for special tools or complicated date setting!
The FlexRing is an annular dampener fitted between case and movement, providing shock protection along both vertical and lateral axes. Machined from a single block of stainless steel, the dampener imparts exceptional robustness to the perpetual calendar.

Over the past 15 years, MB&F creations have transported their wearers to destinations that exist only on maps of the imagination: from star-cruisers to deep-sea jellyfish, Maximilian Büsser’s Machines are the mechanical cartographers of the multiverse.
But the greatest journey has yet to be undertaken, and true progress is marked by evolution. With the LM Perpetual EVO, you become the navigator; the map is your life. On this journey, you’ll never have to leave your watch behind.
The MB&F collection has welcomed several complications and horologically prestigious mechanisms over the past 15 years, including the record-smashing TriAx that debuted in 2019’s Legacy Machine Thunderdome. In terms of combining prestige, tradition and innovation, however, the LM Perpetual has remained at the apex of MB&F watchmaking savoir-faire since it was introduced in 2015.
