MB&F LM Sequential Flyback Longhorn

To celebrate its 20th anniversary, MB&F introduces two limited-edition “Longhorns,” each made in stainless steel and limited to 20 pieces. These timepieces feature rhodium-plated base plates, glossy black lacquer dials, and blue hands. The Longhorn concept originated in 2009 during the design process of the LM1, MB&F’s inaugural Legacy Machine. While the idea of extended lugs, or “horns,” was visually striking, it posed a practical challenge—should the spring bar be placed near the case or at the tip of the lugs? Both options risked a poor fit depending on wrist size. Ultimately, shorter horns replaced the long ones, and the idea was set aside.

Fast forward to 2021, the 10th anniversary of the LM1. With no LM1 models left in production, only a single prototype remained to commemorate the milestone. The question arose: how could this piece stand out even more? Revisiting the longhorn design solved the dilemma.

While most LM1s were made in precious metals or titanium, this one featured stainless steel and glossy black dials—a significant departure from the classic white subdials. Producing the flawless black finish proved challenging, as even a speck of dust could ruin the surface. However, persistence paid off. Phillips later auctioned the piece in collaboration with Bacs & Russo, with proceeds benefiting Save the Rhino International.

The MB&F LM Sequential Flyback Longhorn is the second limited edition in the Longhorn 20th Anniversary series and is another creation by Stephen McDonnell. The initial version, the LM Sequential EVO, debuted in 2022 as MB&F’s first chronograph and 20th calibre. This model introduced groundbreaking technical advancements and unique timing modes, enabled by the “Twinverter” binary switch, which allowed for independent timing, split-second, cumulative, and lap-timer functions. It went on to win the prestigious Aiguille d’Or award.

The Flyback version expanded upon the EVO’s capabilities, incorporating a flyback function originally designed for aviation while retaining the motor-racing-inspired modes. Now featuring extended lugs, blued hands, and glossy black subdials, this second limited edition of 20 pieces marks the start of MB&F’s 20th-anniversary festivities.
