MB&F: Legacy Machine “Longhorn” 20 Anniversary

MB&F’s 20th Anniversary celebrations kick off with two 20-piece Limited Edition “Longhorns” in stainless steel with rhodium-plated base plates, glossy black lacquer dials, and blued hands. 

MB&F’S 20TH ANNIVERSARY 

2025 marks the 20th Anniversary of an adventure that started in 2005 when Maximilian Büsser started putting together a network of “Friends”, on the basis of a drawing that we know now as Horological Machine No.1. Two decades and more than 20 calibres later, the MB&F team includes over 60 employees – what a ride it has been. Reflecting on the last 20 years, Max shares: “It is like a dream come true, only I never dreamt it. I could never have even imagined we would be where we are today back then; it is surreal.” 

This birthday year will be jam-packed with new timepieces, collaborations, and surprises that are a genuine celebration of the art of MB&F creativity, starting with two limited editions – the LM Perpetual Longhorn and the LM Sequential Flyback Longhorn – limited to just 20 pieces each. 

LEGACY MACHINE PERPETUAL LONGHORN 

The first is the LM Perpetual Longhorn, containing MB&F’s GPHG award-winning perpetual calendar first released in 2015. Created in collaboration with independent watchmaker Stephen McDonnell, the 581-component, fully integrated and purpose-built movement eliminates the drawbacks of conventional perpetual calendars, offering a significantly more user-friendly and trouble-free solution. 

McDonnell’s perpetual calendar relies on a ground-breaking “mechanical processor” which avoids skipping dates and jamming gears as the adjuster pushers automatically deactivate when the calendar changes. In this anniversary edition of 20 pieces, McDonnell’s visually stunning in-house movement takes on a whole new aesthetic with the addition of long horns and the black, silver and blue colourway.  (Price CHF 168,000 + TAX)

LEGACY MACHINE SEQUENTIAL FLYBACK 

The second limited edition, the LM Sequential Flyback Longhorn, was also conceived by Stephen McDonnell. The first version of the series, the LM Sequential EVO, was first released in 2022 and was MB&F’s first-ever chronograph – and 20th calibre. It featured significant technical innovations and an unprecedented combination of timing modes thanks to its “Twinverter” binary switch, allowing independent timing, split-second, cumulative and lap-timer modes – going on to win watchmaking’s ultimate prize, the coveted Aiguille d’Or award. 

The Flyback version went even further than the EVO edition as, on top of the previous timing modes, typically associated with motor racing, it added the flyback function originally conceived for pilots, bringing the Sequential into the world of aviation. Now adorned with long horns, blued hands and glossy black sub dials, this second limited edition of 20 pieces is also ready to kick off MB&F’s 20th birthday celebration. (Price CHF 168,000 + TAX)

  “We cannot talk about MB&F’s journey, without talking about Stephen McDonnell,” notes Maximilian Büsser. “It is for this reason that we wanted to start our 20th-anniversary celebrations with his calibres, which are some of the most complicated movements in the MB&F collection.”
