In a bold departure from traditional watchmaking conventions, MB&F has unveiled the LM Sequential Flyback EVO, representing a fundamental reengineering of chronograph technology. Rather than iterating on existing designs, Maximilian Büsser’s horological concept laboratory has completely rethought the chronograph from first principles, creating what may be the most significant advancement in timing complications in recent history.
The LM Sequential Flyback EVO builds upon the groundbreaking foundation established by its 2022 predecessor, which earned the prestigious GPHG Aiguille d’Or award for its innovative approach. This latest evolution introduces the flyback function to the EVO family for the first time, crafted in grade 5 titanium with a striking aquamarine dial plate.
At the heart of this technological marvel is Stephen McDonnell’s mechanical genius, previously demonstrated in the LM Perpetual. The timepiece features two fully independent chronographs, each with dedicated seconds and minutes displays and separate pushers. The revolutionary Twinverter mechanism at the nine o’clock position operates as a binary switch that can simultaneously control both chronographs—starting, stopping, or alternating between them with a single press.
This architecture enables unprecedented timing capabilities, from split-second comparisons to cumulative tracking across multiple simultaneous events. The integrated flyback function allows for instantaneous resetting and restarting of running chronographs, significantly enhancing practical usability.
The mechanical sophistication required to make this complex system reliable is extraordinary. McDonnell’s solution incorporates internally jewelled vertical clutches combined with specially developed jewelled rollers within the flyback system, minimizing friction and energy loss despite two chronographs sharing the same movement.
Visually, the timepiece maintains the distinctive EVO aesthetic with its bezel-free design that opens the dial beneath the domed sapphire crystal. The inclined time display at six o’clock improves legibility while creating a more intimate connection between the watch and wearer.
Priced at CHF 168,000, the LM Sequential Flyback EVO represents not just technical achievement but a philosophical statement about the future of high-complication watchmaking—demonstrating that true innovation lies not in adding complexity but in making complexity feel intuitive and human-centered.
