Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
MB&F Legacy Machine 43 mm Blue 18k sits within MB&F's Legacy Machine line, introduced in 2005. It carries the house codes established since 2005 — 18k white gold case, blue "grande tapisserie" 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.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- 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.
