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







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



What you need to know regarding this watch?



Nonetheless McDonnell's initial vision proceeded to go far beyond this. The prototype movement actually bundled a flyback chronograph technique, 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 dependable goal was finally understood in 2024 with the introduction of the LM Sequential Flyback watch, featuring a classic Legacy Machine case. Now, the idea joins the sportier EVO series as the LM Continuous Flyback EVO, renowned due to its Grade 5 titanium event and striking aquamarine face.



The addition of the actual flyback function elevates this kind of already remarkable complication for you to near-chronograph pinnacle. Standard continuous chronograph configurations require a few operations-stop, reset, and restart-to begin a new chronograph string, while the flyback function streamlines this to a single hit of the reset button as the chronograph is running. This specific seemingly minor improvement drastically expands its practical apps, especially when combined with dual-frequency conversion to simultaneously switch involving two chronograph functions.



In terms of aviation chronograph watches, the essence of a flyback wathe lies in this: one termes conseillés records the total flight period, while another timer procedures each segment and resets instantly between segments. Like in endurance racing, any time lap times exceed one minute, traditional split-seconds chronographs grow to be inadequate-flyback chronographs, with their small counters at 11 and also 1 o'clock, can track record longer time intervals, even though the flyback function enables speedy sequential timing without waiting around for time recording.



The technological achievements right behind this function are exceptional. McDonnell's integrated jewel-bearing top to bottom clutch eliminates the boundlessness fluctuations common in classic chronograph systems, while the flyback mechanism itself uses especially designed jewel-bearing rollers-components normally from standard suppliers-to decrease friction that could affect the zeroing function. These innovative technological innovation constitute five patents inside 621 components and 63 jewels of the sequential motion. A 72-hour power reserve makes certain reliable operation even through extended wear.



The EVO version remains MB& F's signature performance-minded style: 80-meter water resistance, some sort of screw-down crown, an integrated silicone strap, and the FlexRing shock-absorbing system to protect the movements during sporty wear. Additionally, this version retains timeless Sequential model's tilted moment display-the sub-dial at some o'clock tilts towards the user for improved legibility. Typically the flying balance wheel is still at 12 o'clock, it is 21, 600 vibrations by the hour clearly visible, reminding us all that both timing methods share the same escapement-a layout that allows the watch to achieve this sort of comprehensive timing functions devoid of the timing errors that can appear with multiple independent elements.



For hobbyists who recognized the importance of the particular Sequential EVO three years in the past, this titanium version using flyback function represents an adult expression of the movement-McDonald's primary vision finally realized inside MB& F's most distinctive case.
