Experience Unrivaled Precision: The MB&F LM Sequential Flyback EVO

Evolution of an Award-Winning Chronograph: From Platinum to Titanium

Building upon the esteemed foundation of the 2022 LM Sequential EVO, MB&F has unveiled a new iteration that amplifies ruggedness and versatility. This latest creation integrates advanced structural enhancements, preparing the timepiece for a more dynamic and adventurous existence. The watch now resides within a lightweight yet resilient titanium casing, thoughtfully equipped with shock-absorbing mechanisms, a secure screw-down crown for enhanced water resistance, and other practical features designed for everyday challenges.

Stephen McDonnell's Vision: Redefining Chronograph Functionality

Stephen McDonnell, the horological genius behind the 2015 Legacy Machine Perpetual, once again demonstrates his innovative spirit. Tasked with crafting MB&F's inaugural chronograph, McDonnell delivered the revolutionary LM Sequential EVO. This remarkable watch features two independent column-wheel chronographs, both synchronized with a single oscillator. A distinctive Twinverter switch allows for seamless transitions between four distinct timing modes, showcasing an unprecedented level of operational flexibility.

Elevated Complication: The Flyback Function in 2024

In 2024, McDonnell further elevated the watch's complexity by incorporating a flyback complication into the chronograph. This addition transformed it into the LM Sequential Flyback, boasting five unique timing modes, including the flyback functionality for both chronographs. Initially, this advanced mechanism was housed within a classic platinum Legacy Machine case, featuring five pushers and a screw-down crown, though with a moderate 30-meter water resistance.

The EVO Treatment: Ready for Any Adventure

Now, the LM Sequential Flyback embraces the robust EVO treatment. It features a 44mm titanium case, standing 18.2mm tall, complemented by an aquamarine dial plate. A notable enhancement is the newly designed tilted dial, significantly improving readability. First introduced with the LM Perpetual in 2020, MB&F's EVO enhancements include the proprietary FlexRing shock absorber, strategically placed between the case and the movement to protect its delicate mechanics during vigorous activities. Additional EVO features, such as the screw-down crown, ensure water resistance up to 80 meters. The sculpted, sandblasted lugs contribute to a contemporary, sporty aesthetic, perfectly matched with an integrated white rubber strap.

Enhanced Legibility and Distinctive Display Elements

While maintaining the familiar layout and functions of its classical counterpart, the LM Sequential Flyback EVO features distinctive double chronograph counters. Positioned at 9 and 3 o'clock for 60-second intervals, and at 11 and 1 o'clock for 30-minute measurements, these counters are presented in black with crisp white numerals and hands treated with Super-LumiNova for optimal visibility. Dominating the visual landscape above these counters is the iconic flying balance wheel. Furthermore, the black hours and minutes disc is now angled towards the wearer, coupled with luminous hands to ensure effortless time-telling.

The Twinverter: A Master of Timing Modes

The timepiece features four pushers dedicated to the dual flyback chronograph mechanisms. A crucial fifth pusher, positioned at 9 o'clock, activates the innovative Twinverter. This ingenious "magic button" simultaneously manages both chronographs, instantly altering their operational state. This allows users to start, stop, or swap between chronographs with a single press. The Twinverter supports a variety of timing applications, including independent, simultaneous, split-second, cumulative, sequential (lap-timer), and flyback modes.

Power and Precision: The Ingenious Movement

The intricate design of a single movement powering two independent chronographs necessitates significant energy. To address this, McDonnell engineered jeweled vertical clutches, which effectively minimize friction and prevent the flyback mechanism from encountering the return-to-zero obstruction. A specialized jeweled roller was developed specifically for the flyback function, enabling the Sequential caliber to surpass conventional chronographs in both energy efficiency and timing accuracy.

Exquisite Craftsmanship and Technical Specifications

This fully integrated dual chronograph manual-winding movement comprises 621 components and operates at 3Hz, offering a robust three-day power reserve, thanks to its double mainspring. The movement is meticulously adorned with hand-finishing, featuring darkened bridges with a NAC finish that elegantly contrast with polished bevels and vibrant rubies. The LM Sequential Flyback EVO is available for CHF 168,000 + VAT (EUR 181,000 / USD 230,000 + tax), representing a pinnacle of horological artistry and engineering.
