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 HM11 39 mm Green Grade sits within MB&F's HM11 line, introduced in 2005. It carries the house codes established since 2005 — grade 5 titanium case, green sunburst dial and in-house automatic with 22k gold rotor — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

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.
