MB& F LM Sequential Flyback EVO - Titanium and Aquamarine Dial







In 2022, MB& F's LM Sequential EVO won the Grand Tarifs d'Horlogerie de Genève (Gold Hand) at the Grand Prix des Haute Horlogerie within Geneva, confirming what experienced collectors already knew: Sophie McDonnell redefined the chronograph's function with rigorous concept and revolutionary practice. This particular watch features a dual wathe architecture, controlled by a advanced Twinverter double-position switch, attaining independent chronograph, split-seconds, timepiece, and lap time features within a 44mm case-such effective functionality raises the issue of why traditional chronograph watches are so limited in functionality.



What you need to know concerning this watch?



But McDonnell's initial vision gone far beyond this. Their prototype movement actually integrated a flyback chronograph program, but perfecting this perform took nine months as well as underwent six complete renovations. Its complexity prevented the integration with numerous unproven innovative technologies. This driven goal was finally recognized in 2024 with the release of the LM Sequential Flyback watch, featuring a classic Legacy Machine case. Now, this joins the sportier EVO series as the LM Continuous Flyback EVO, renowned because of its Grade 5 titanium situation and striking aquamarine switch.



The addition of the actual flyback function elevates this particular already remarkable complication in order to near-chronograph pinnacle. Standard continuous chronograph configurations require 3 operations-stop, reset, and restart-to begin a new chronograph series, while the flyback function makes simple this to a single push of the reset button as the chronograph is running. This specific seemingly minor improvement considerably expands its practical programs, especially when combined with dual-frequency conversion software to simultaneously switch among two chronograph functions.



In terms of aviation chronograph watches, the essence of a flyback time counter lies in this: one termes conseillés records the total flight period, while another timer steps each segment and resets instantly between segments. Like in endurance racing, whenever lap times exceed one minute, traditional split-seconds chronographs turn out to be inadequate-flyback chronographs, with their moment counters at 11 and also 1 o'clock, can document longer time intervals, even though the flyback function enables quick sequential timing without awaiting time recording.



The technological achievements driving this function are amazing. McDonnell's integrated jewel-bearing up and down clutch eliminates the plenitude fluctuations common in conventional chronograph systems, while the flyback mechanism itself uses specifically designed jewel-bearing rollers-components not attainable from standard suppliers-to reduce friction that could affect the zeroing function. These innovative technology constitute five patents inside the 621 components and 63 jewels of the sequential motion. A 72-hour power reserve guarantees reliable operation even throughout extended wear.



The EVO version proceeds MB& F's signature nice style: 80-meter water resistance, the screw-down crown, an integrated rubberized strap, and the FlexRing shock-absorbing system to protect the movements during sporty wear. In addition, this version retains typical Sequential model's tilted moment display-the sub-dial at six o'clock tilts towards the individual for improved legibility. The actual flying balance wheel continues to be at 12 o'clock, it is 21, 600 vibrations hourly clearly visible, reminding all of us that both timing techniques share the same escapement-a style that allows the watch to achieve this kind of comprehensive timing functions with no timing errors that can happen with multiple independent systems.



For enthusiasts who recognized the importance of the particular Sequential EVO three years back, this titanium version along with flyback function represents an adult expression of the movement-McDonald's preliminary vision finally realized inside MB& F's most unique case.
