MB&F Legacy Machines watches

The MB&F Legacy Machines are the round-cased line MB&F began in 2011 with the Legacy Machine No.1. They started from a question: what would Maximilian Büsser have made had he founded MB&F in the 19th century? That ruled out muscle cars and spaceships and brought in Jules Verne, the Eiffel Tower and antique pocket watches. The signature is a balance wheel lifted high above the dial, swinging under an arched bridge.

The LM1 set the pattern. Its hand-wound movement was developed with Jean-François Mojon and finished under Kari Voutilainen, with a 14 mm flying balance, two time zones set independently, a vertical power reserve indicator and 45 hours of reserve. It won Best Men's Watch and the Public Prize at the 2012 GPHG and closed in 2017 with a steel Final Edition. The LM2 of 2013 uses two 11 mm balances whose rates a differential averages. The LM101 of 2014 shrinks the case to 40 mm, shows just hours, minutes and power reserve, and has MB&F's first in-house movement; the H. Moser versions give it a fumé dial with no logos or indices.

The Perpetual of 2015, developed with Stephen McDonnell, builds its calendar from a 28-day month, adding days as needed, and won Best Calendar Watch at the 2016 GPHG. The Perpetual EVO puts it in a zirconium case without a bezel, with a screw-down crown and 80 m water resistance. The Split Escapement, derived from McDonnell's movement, moves the anchor and escape wheel below the dial and leaves the balance alone above it; engraver Eddy Jaquet made eight unique red gold versions, each named for a Jules Verne novel. The Thunderdome carries Eric Coudray's triple-axis tourbillon, its cages turning in 8, 12 and 20 seconds.

The FlyingT of 2019 was MB&F's first watch for women and the first automatic Legacy Machine: 38.5 mm, a central flying tourbillon and a time dial at 7 o'clock tilted at 50 degrees. The LMX of 2021 marked ten years of the line, returning to two inclined time-zone dials with a seven-day reserve.
