With the LM Sequential Flyback EVO, MB&F expands its most technically advanced chronograph concept by adding flyback functionality to the EVO collection.
The new model builds on the brand’s distinctive approach to chronograph design while reinforcing the robustness and wearability that define the EVO line.
To understand its significance, it is worth returning to 2022, when MB&F introduced the LM Sequential EVO. Developed in collaboration with independent watchmaker Stephen McDonnell, the movement integrated two fully independent chronographs within a single calibre, controlled by the groundbreaking Twinverter binary switch.
This architecture offered an unprecedented combination of timing modes: independent timing, split-second, lap timer and cumulative timing, all united within a single movement.
The hand-finished dual column-wheel chronograph system also incorporated patented internally jewelled vertical clutch shafts, outperforming conventional chronographs in terms of energy efficiency and precision. For these reasons, the LM Sequential EVO received the GPHG Aiguille d’Or for Best Watch of the Year.
But this achievement was not the end of the story. After a further two years of development, Stephen McDonnell raised the bar again by introducing flyback functionality on both chronographs. This evolution debuted with the LM Sequential Flyback Platinum, followed by the LM Sequential Flyback Longhorn 20th Anniversary.
MB&F now extends this flyback functionality to the EVO line with the LM Sequential Flyback EVO, housed in a Grade 5 titanium case with an aquamarine dial plate and a tilted display designed to improve legibility.
This new edition incorporates all the defining EVO features: water resistance increased to 80 metres, a screw-down crown, an integrated rubber strap and the FlexRing shock-absorbing system.
Aesthetically, the EVO models are defined by an ergonomic 44 mm × 18.2 mm case, characterised by the absence of a traditional bezel, which offers an open view of the luminous displays beneath a domed sapphire crystal.
Darkened movement finishes further reinforce the collection’s modern, sporty character.
The LM Sequential Flyback EVO retains the same twin-chronograph layout as the LM Sequential EVO. One chronograph displays seconds at 9 o’clock and minutes at 11 o’clock, while the other places seconds at 3 o’clock and minutes at 1 o’clock.
Each chronograph can be operated independently using its own start, stop and reset pushers. With the flyback function, a running chronograph can be reset and restarted instantly with a single press.
In addition to the four chronograph pushers, the watch features a fifth pusher at 9 o’clock, known as the Twinverter. This controls both chronographs simultaneously by reversing their running status: starting both, stopping both, or switching one on while stopping the other.
This system gives the LM Sequential Flyback EVO a level of flexibility unmatched by conventional chronographs.
The design of the Sequential calibre — comprising 621 components and operating at a frequency of 3 Hz (21,600 vibrations per hour) — is entirely original.
It integrates two independent chronograph mechanisms within a single movement, both connected to a shared escapement and oscillator.
In conventional chronographs, energy losses are inherent to the system; incorporating two chronographs in one movement would normally compound these losses and compromise performance. Addressing this challenge required the development of a fundamentally new chronograph architecture, designed to avoid the typical drawbacks associated with energy consumption.
This is achieved through the Sequential calibre’s patented internally jewelled vertical clutches and dedicated control system. The flyback mechanisms also employ jewelled rollers to further reduce friction.
Together, these solutions ensure high energy efficiency and consistent precision, allowing the Sequential calibre to surpass traditional chronograph constructions in both performance and reliability.
Through the transparent sapphire crystal caseback, it is possible to appreciate the hand-finished movement, including internal angles, polished bevels, Geneva waves, hand-made engravings and darkened NAC-treated bridges. The 72-hour power-reserve indicator is also visible on this side.
The MB&F LM Sequential Flyback EVO in Grade 5 titanium with an aquamarine dial plate is priced at CHF 168,000 / €181,000 / US$230,000, excluding sales taxes. mbandf.com
