Designer

Gérald Genta

Gérald Genta (1931–2011) trained as a goldsmith in Geneva and became the most influential watch designer of the 20th century. Working freelance, he sketched the Audemars Piguet Royal Oak overnight in 1970, followed by the Patek Philippe Nautilus, the IWC Ingenieur SL and the Bulgari Bulgari — defining the integrated-bracelet luxury sports watch as a category.

Historical significance

MB&F LMX 43 mm Green 18k sits within MB&F's LMX line, introduced in 2005. It carries the house codes established since 2005 — 18k rose gold case, green sunburst dial and in-house automatic micro-rotor — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

  • The movement's bridges are decorated even where they will never be seen once the watch is cased.
  • The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
  • The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history

MB&F has spent more than 21 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Horological Machine, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.

Maximilian Büsser established MB&F in 2005, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every MB&F calibre produced today.
