LM PERPETUAL EVO

Not a watch for sport. A watch for life.

A 44mm case in zirconium, a lustrous silvery-grey metal with material properties surpassing stainless steel and titanium. 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. Three options of PVD/CVD dial-plate colour, including — for the first time in a high-end piece of Swiss watchmaking — atomic orange. And a closely-fitted, integrated strap for the smoothest wearing experience of any MB&F Machine ever.

Although the 44mm diameter is unchanged from its 2015 iteration, the new EVO case design features a no-bezel construction, with the domed sapphire crystal fused directly to the case. The increased openness of this design highlights the equilibrium between the legibility of LM Perpetual EVO’s calendar indications and the cinematic play of the engine components — surmounted by the iconic MB&F hovering balance wheel. This expansive new presentation of the LM Perpetual Engine was no simple design reconfiguration. New geometries for the sapphire crystal had to be calculated, achieving the mechanically opposing aims of maintaining structural strength and decreasing its height-to-diameter ratio. Freeing LM Perpetual EVO from the bezel also necessitated the use of a sophisticated thermal bonding system between the sapphire crystal and the zirconium case.
The previously circular pushers for adjusting the perpetual calendar have been enlarged into double-sprung oblong actuators, boosting the tactile comfort and ease of adjustment. For the first time in any MB&F creation, the LM Perpetual EVO is rated at 80m of water resistance, enabled
by its screw-down crown. A small, but essential, detail of implementing a screw-down crown is the débrayage of the winding stem, disengaging the crown from the winding mechanism when it is pushed in and tightened, which eliminates the chance of manually over-winding the mainspring barrel.

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. Presenting Legacy Machine Perpetual EVO: with this new Machine, you are the navigator; the map is your life. On this journey, you’ll never have to leave your watch behind.
