MB&F Revives the Legacy Machine N°1 as the LM1 EVO
An inclined display at 6 o’clock replaces the original vertical indicator while autonomy rises to 60 hours.
Summary
MB&F revives the Legacy Machine N°1 as the sportier LM1 EVO.
The 42mm watch keeps independent dual time while adding FlexRing shock protection.
Titanium and rose-gold versions feature a 60-hour reserve and Straumann double hairspring.
15 years after the Legacy Machine N°1 opened a new chapter for MB&F, the watchmaker is bringing its foundational dual-time concept into the sportier EVO family with the new LM1 EVO. First introduced in 2011, the original LM1 represented a more classical side of MB&F, drawing from 19th-century watchmaking while retaining the brand’s unmistakably three-dimensional architecture; it went on to claim both the Public Prize and Best Men’s Watch at the 2012 GPHG awards.
The 2026 edition preserves its defining layout – two completely independent hour-and-minute displays flanking a suspended 14mm balance wheel – while shrinking the case from 44mm to 42mm and incorporating the everyday-focused upgrades associated with the EVO series. Crucially, the two time zones remain independently adjustable rather than operating like a conventional GMT, allowing for unusual 30- and 45-minute offsets.
The biggest changes sit around, and within, that familiar architecture. The LM1’s original vertical power-reserve display has been replaced by a more legible inclined indicator at 6 o’clock, while the manually wound calibre now delivers 60 hours of autonomy, up from 45 hours previously. Its oversized floating balance wheel continues to beat at a traditional 2.5 Hz, but is now fitted with a Straumann double hairspring, using two opposing hairsprings to improve positional consistency and isochronism.
A redesigned titanium bridge further emphasizes the regulating organ as part of the visual composition. Around it, the EVO treatment adds MB&F’s FlexRing shock-absorbing system, dual screw-down crowns, 80 meters of water resistance and a bezel-free case topped by a high-domed sapphire crystal. Integrated rubber straps are also interchangeable at both the case and folding clasp, making the traditionally elaborate Legacy Machine considerably easier to wear day to day.
The LM1 EVO launches in two configurations. A Grade 5 titanium version pairs its lightweight case with a rhodium-plated dial plate, black displays and blue accents, while a warmer 5N+ rose-gold edition combines the same architecture with a deep green dial plate and rose-gold-toned details. The latter is limited to just 33 pieces, while the titanium edition is not presented as a limited run. Both versions are available now through MB&F and its retail network, priced at $109,000 USD for titanium and $137,000 USD for rose gold.
