LEGACY MACHINE N°1 EVO
THE ORIGINAL DUAL-TIME LEGACY MACHINE, EVOLVED
Fifteen years after Legacy Machine No1 opened a new chapter in MB&F’s story, the LM1 returns. LM1 EVO preserves the unmistakable architecture and fully independent dual time zones of the original, while introducing a smaller case, redesigned power reserve indicator, and the everyday wearability of the EVO collection – now with interchangeable straps.
Back to the future, again
In 2011, Legacy Machine N°1 opened an entirely new chapter for MB&F: a more classic, round-cased Machine inspired by the great innovators of 19th-century traditional watchmaking, yet unmistakably three-dimensional… and unmistakably MB&F. Powered by an in-house, superlatively finished caliber developed with Jean-François Mojon and Kari Voutilainen, LM1 received both the Public Prize, and the Best Men’s Watch Prize in 2012 at the Grand Prix d’Horlogerie de Genève. Fifteen years later, the Machine that started the Legacy story returns in a new form: LM1 EVO.
The defining architecture remains immediately recognizable. Two separate dials display two completely independent time zones, while the monumental 14mm balance wheel – now combined with a Straumann® double hairspring – still appears to float above the movement at the center of the stage. But this is no exercise in nostalgia. LM1 EVO has been re-engineered for a different kind of life: longer-running, easier to live with, and protected by the performance-driven EVO case.
The upgraded caliber extends the power reserve to 60 hours and moves its indication from the original sextant-like display to a sportier, inclined dial at 6 o’clock. The case, now 42mm in diameter (vs. the original 44mm), integrates MB&F’s FlexRing shock-absorbing system and offers 80 meters of water resistance with screw-down crowns. An interchangeable strap system completes the transformation, turning MB&F’s foundational Legacy Machine into a companion designed for active use.
Two times, with no compromise
At the heart of LM1 has always been an unusually pure approach to dual time. The two sub dials are not simply two displays linked by a conventional GMT mechanism: each indicates its own hours and minutes, allowing the two time zones to be set completely independently. That means the second display is not restricted to full-hour offsets – a useful distinction in the parts of the world where local time differs by 30 or 45 minutes. Another useful application: one of the dials can also be used to measure elapsed time, while the other steadily keeps the time.
On LM1 EVO, the left and right displays retain the visual tension that made the original Machine so distinctive. The crown at 4 o’clock winds the movement and sets the right-hand time display, while the crown at 8 o’clock adjusts the second time zone on the left. The result is intuitive, symmetrical and – in true MB&F fashion – mechanically more elaborate than the apparently simple indication suggests.
