MB&F elevates its LM Sequential EVO with a patented Flyback function

As MB&F enters its second decade, this new complication symbolizes the fusion of the brand’s heritage with its future, through innovative horology.

Renowned for his masterful creations at MB&F, Stephen McDonnell makes a triumphant return with the unveiling of the LM Sequential Flyback Platinum.

Mr. McDonnell, the creative force behind the award-winning LM Sequential EVO chronograph, has now finally realized his vision of incorporating a flyback function into the timepiece. This addition posed a formidable challenge, requiring meticulous design and two years of testing. The result is a groundbreaking advancement in chronograph technology, fundamentally altering its design paradigm.

The addition of a flyback function allows the reset pushers to trigger the flyback while the corresponding chronograph is running. Notably, a fifth pusher, the Twinverter, positioned at 9 o’clock, acts as a “magic button,” enabling simultaneous starting or stopping of both chronographs. This innovation, conceived by Mr. McDonnell, enhances the functionality of the LM Sequential series, revolutionizing conventional chronograph wristwatches. It eliminates the need to fumble with multiple buttons for the same function.

The intricate jeweling within the vertical clutches forms the cornerstone of the Sequential chronograph, while the newly integrated flyback system necessitates its own jeweling for functionality. Mr. McDonnell’s meticulous engineering focused on minimizing friction to ensure seamless operation, particularly in preventing the flyback from impeding the return-to-zero function. To achieve this, he introduced a bespoke jeweled roller into the flyback mechanism, a component not readily available from suppliers. For the initial prototype, McDonnell personally crafted the jewel to validate the innovative concept, one of five patented elements in this pioneering mechanism.

The dial bears a striking resemblance to the LM Sequential EVO chronograph, while the model embodies an entirely different aesthetic. Sporting five pushers, the 44mm platinum case boasts a height of 18.2mm. Notably, the lower pushers now feature an engraved inscription reading “FLYBACK” and it has a water resistance of up to 30 meters.

The LM Sequential Flyback Platinum inherits the layout of its predecessor, the LM Sequential EVO, featuring two chronograph displays. One set displays seconds at 9 o’clock and minutes at 11 o’clock, while the other reverses this placement. Each chronograph operates independently, controlled by pushers on either side of the case.

Limited to only 33 pieces, the timepiece is offered at USD 218,000.
