MB&F Recasts the Legacy Machine 1 as the Sportier LM1 EVO

The Legacy Machine 1 has always occupied a special place in MB&F’s history.

When it arrived in 2011, it proved the brand could look backward without losing its taste for mechanical theatre, placing 19th-century watchmaking cues inside a deeply contemporary three-dimensional construction.

Now the LM1 returns as the LM1 EVO, a more robust and wearable evolution that keeps the original’s dual-time drama while adding the practical armour of MB&F’s EVO line.

At a glance

From pocket-watch romance to EVO armour

The original LM1 was a turning point because it stepped away from MB&F’s space-age Horological Machines and introduced the brand’s first round case.

Its Roman numerals, lacquered registers and classical finishing could have felt conservative in another context, but the suspended balance wheel and open architectural layout made it unmistakably MB&F.

The LM1 EVO keeps that tension intact.

It still reads as a machine with old-world manners, but it’s now housed in a case designed for more than collector-safe handling.

The EVO treatment brings a bezel-free case profile, two screw-down crowns, 80 metres of water resistance and MB&F’s patented FlexRing shock-absorption system.

That makes the LM1 EVO less fragile in daily use, without turning it into a conventional sports watch.

The familiar LM1 stage gets sharper

The new case measures 42mm across, 16.8mm thick and 52mm from lug to lug.

It’s smaller than the original 44mm LM1, yet the hyper-domed sapphire crystal preserves the sense of vertical spectacle that defines the watch.

MB&F uses a thermal bonding process to fuse the crystal directly into the metal case, a construction choice intended to improve structural strength while allowing more light onto the dial plate.

The layout remains centred on two independent time displays, each adjusted by its own crown.

That system is particularly useful because each sub-dial can be set independently to the minute, rather than being limited to standard whole-hour travel offsets.

Above the movement, the 14mm balance wheel remains the visual anchor, now held beneath a redesigned titanium bridge.

The power reserve indication has also changed, moving to an inclined semi-circular arc at 6 o’clock to track the increased 60-hour running autonomy.

A tougher movement with classical finishing

The manual-winding three-dimensional calibre was developed in-house by MB&F with Jean-François Mojon.

It now uses a Straumann double hairspring with the slow-beating 2.5Hz balance, a technical update aimed at improving accuracy and isochronism.

The finishing remains deliberately traditional, with aesthetic oversight by Kari Voutilainen.

Details include Geneva waves, polished bevels with internal angles, gold chatons with polished countersinks, handmade engravings and contemporary NAC black bridges.

That contrast is central to the LM1 EVO’s appeal.

It’s a watch that borrows the vocabulary of 19th-century hand-finishing, then presents it as a suspended mechanical sculpture built for the present day.

Titanium restraint or rose gold theatre

The LM1 EVO comes in two distinct versions.

The grade 5 titanium model pairs a rhodium-plated dial plate with black snailed sub-dials and blue arrow-tipped hands with luminescence.

The 18k rose gold edition takes a warmer route, using a rich green dial plate, black sub-dials and gold-toned hands with luminescent inlays.

Both versions sit on integrated rubber straps, with black rubber for titanium and grey rubber for rose gold.

For the first time in this family, the straps use a quick-release system at both the case and clasp, making the EVO brief more practical without disturbing the case architecture.

Details & Specifications

The LM1 EVO works because it doesn’t try to smooth out the eccentricity of the first Legacy Machine.

Instead, it gives that founding idea a stronger case, a more usable strap system and a movement update that makes the return feel purposeful rather than nostalgic.
