The New Onyx Edition of the MB&F LM Flying T

A unisex version with no diamonds, an inky black onyx dial plate and a sleek, black-tie spirit.

MB&F undertook its maiden voyage into the galaxy of women’s watches with the launch of its Legacy Machine Flying T in 2019. After 14 years of masterminding complex watches for men, Max Büsser’s Legacy Machine Flying T flaunted all the attributes associated with MB&F watches but in a more feminine format – or even a very feminine format when teaming up with Bulgari. For 2024, the watch shifts gear and returns in more unisex attire with a sleek black onyx dial plate and an 18k yellow gold case without diamonds.

The latest Legacy Machine Flying T could be classified as the black-tie version of this model. With no diamonds highlighting the case, the model is closer in spirit to the non-diamond-set Flying T Red Gold of 2020 with its guilloché dial plate. Considering that many of MB&F’s watches are too large for men with smaller wrists, the more restrained dimensions and toned-down styling of the Flying T make it a viable option for both sexes.

Like all editions of the LM Flying T, the yellow gold polished case measures 38.5mm across and has a height of 20mm, including the pronounced domed sapphire crystal crowning the spectacle on the dial.

The inky black onyx dial plate and the inclined hours and minutes disc contrast dramatically with the polished 18K yellow gold case. As a member of the Legacy Machine dynasty, the Flying T is a complex kinetic creation that replaces the suspended balance wheel of its bloodline with a flying tourbillon. Rising from the asymmetric opening in the centre of the dial, the tourbillon is supported by a column construction and held in place by the signature double-arched bridge of the LM family, topped by a diamond. Matching the case material, the frame of the ventricular aperture, the 50º inclined sub-dial, and the squiggly serpentine hour and minute hands are crafted in gold.

The reverse side reveals a sculpted gold sun-shaped rotor. The vertical architecture and conical gears of the Legacy Machine Flying T’s movement borrow solutions from both the HM6 series and the HM7 Aquapod. Its tourbillon regulator beats at a leisurely frequency of 18,800vph, and the barrel can deliver an impressive four-day power reserve, one of the highest in MB&F’s portfolio.

The new onyx edition of the MB&F LM Flying T comes with a handsome black alligator (or calfskin) leather strap with a gold pin buckle and retails for CHF 114,000, EUR 120,000 or USD 138,000 (all prices excl. tax). For more information, please visit
