In celebration of its 20th anniversary, MB&F has unveiled two remarkable limited-edition timepieces: the LM Perpetual Longhorn and the LM Sequential Flyback Longhorn. These watches are not only tributes to the brand’s journey but also masterpieces that incorporate innovative design and high-level craftsmanship. Let’s explore both pieces in detail:
MB&F LM Perpetual Longhorn
Design & Aesthetics
The LM Perpetual Longhorn is crafted from stainless steel, marking a distinctive choice from the conventional use of precious metals, reflecting the brand’s unconventional spirit.
The watch features rhodium-plated base plates combined with glossy black lacquer sub-dials and blued hands, creating a striking contrast that enhances its sophistication.
The standout feature is the “long horns” – elongated lugs offering dual attachment points, allowing for a better fit on varied wrist sizes, a revisited concept from the original LM1 design phase.
Movement
This timepiece is powered by a fully integrated perpetual calendar movement conceived by Stephen McDonnell. It eliminates common issues in traditional perpetual calendars, like skipping dates and jamming gears.
The innovative “mechanical processor” architecture is designed for seamless operation and maintenance, keeping complications trouble-free.
It has a power reserve of 72 hours, operating at a frequency of 2.5Hz (18,000 vph), and consists of 581 components with 41 jewels in the movement.
Specifications
The case measures 44 mm in diameter and 17.5 mm in thickness. It is equipped with anti-reflective sapphire crystals on both sides. The piece comes with a calf leather strap and a stainless steel folding buckle, elevating comfort and style.
MB&F LM Sequential Flyback Longhorn
Design & Aesthetics
Similarly housed in a stainless steel case, the LM Sequential Flyback Longhorn shares the sleek design elements of glossy black lacquer dials and elegant blued hands.
The long horns add a boldness to its structure, resonating with the adventurous spirit that MB&F has championed over the years.
Movement
Developed in collaboration with Stephen McDonnell, this watch interprets the chronograph function with its patented “Twinverter” feature, allowing multiple timing modes in a single watch.
The chronograph functions include independent, split-second, cumulative, sequential, and the key flyback mode, making it a versatile tool for various timing needs.
It runs on a manual winding movement, supported by a dual mainspring system, providing a 72-hour power reserve and operating at a frequency of 3Hz (21,600 vph).
Specifications
The case dimensions are slightly larger at 44 mm by 18.2 mm, catering to the flyback functionality and dual chronograph implementation. The watch includes a sapphire crystal display case back with anti-reflective treatment. It is paired with a calf leather strap and stainless steel folding buckle, ensuring a secure and elegant fit.
A Tribute to Collaboration and Innovation
Both anniversary editions underscore MB&F’s ethos of collaborative creativity and technical mastery. They highlight the contribution of Stephen McDonnell, whose collaboration through complex movements represents MB&F’s commitment to pushing boundaries.
These pieces not only celebrate MB&F’s illustrious two-decade journey of innovation and artistry but also invite collectors and admirers to become part of this commemorative adventure, poised to set new benchmarks in haute horology.
