Introducing MB&F Unveils the M.A.D.1S and LM101 Longhorn Special Editions

As part of its ongoing 20th anniversary celebrations, MB&F is offering collectors and enthusiasts alike the chance to win two very special editions: the M.A.D.1S 20th Anniversary and the LM101 Longhorn 20th Anniversary. For the first time, the opportunity extends not only to the brand’s Tribe members, the highly valued owners of MB&F Machines – but also to the thousands of watch enthusiasts who have participated in M.A.D.Editions raffles over the years, many without success.

In total, 20 watches will be raffled across two limited series of 10 pieces each timepieces that will never be commercialised otherwise: 10 LM101 Longhorns and 10 M.A.D.1S 20th Anniversary models.

Both editions feature stainless steel cases with a refined colour palette of silver, black, and blue, echoing the LM Sequential Flyback and LM Perpetual Longhorn Anniversary Editions launched earlier this year. Those earlier Longhorn pieces drew inspiration from the one-off LM1 Longhorn Pièce Unique, created for charity in 2021, which featured a grey rhodium dial plate contrasted with black sub-dials.

The LM101 Longhorn 20th Anniversary will be raffled exclusively among registered Tribe members who have entered their MB&F Machines into the collectors’ database. Details will be communicated directly to owners, with the 10 lucky winners invited to Geneva to collect their new Machine in person at the MB&F M.A.D.House.

At the same time, MB&F is extending gratitude to its wider circle of fans. Thousands of enthusiasts who have registered for M.A.D.Editions raffles in the past will be automatically entered into a draw for one of the 10 M.A.D.1S 20th Anniversary watches. Both raffles will be held in October, under the supervision of a bailiff to ensure fairness.

The LM101 Longhorn 20th Anniversary

Introduced in 2014, the LM101 series is one of MB&F’s most compact and elegant Machines, with a 40 mm case housing a strikingly three-dimensional, hand-finished movement created in collaboration with master watchmaker Kari Voutilainen. True to its name, LM101 focuses on the essentials of horology: the iconic “flying” balance wheel regulating timekeeping, the power reserve indicator, and the display of hours and minutes.

Over the past decade, LM101 has become a cornerstone of MB&F’s collection. The Longhorn variant takes its name from its elongated lugs, or “horns,” a design reserved only for special editions: the Pièce Unique LM1 for charity, and the LM Perpetual and LM Sequential Flyback Longhorn anniversary models.

The new LM101 Longhorn 20th Anniversary Edition carries the same signature features: a radiant sunburst rhodium-plated dial plate, contrasting black sub-dials, and blued hands. On the reverse, a commemorative sapphire crystal bears the anniversary inscription: “Fortune Favours the Bold” – a reminder of MB&F’s philosophy of daring creativity.

The M.A.D.1S 20th Anniversary

The celebratory edition builds on the M.A.D.1S, the most recent evolution of the M.A.D.1 line, distinguished by a slimmer case and lugs, a single rotating cylinder, and a Swiss-made La Joux-Perret G101 base calibre.

To mark the occasion, the M.A.D.1S 20th Anniversary adopts several design cues from its LM101 Longhorn counterpart. For the first time in a M.A.D.Edition, the hours and minutes cylinder is decorated with Roman numerals. Its silver and black palette is highlighted by a vivid blue ring beneath the bezel, subtly echoing the Longhorn’s blued hands. The watch is paired with a light brown leather strap, adding understated refinement.

On the caseback, an engraved motto ties the two anniversary models together: “Fortune Favours the Bold.”
