MB&F Horological Machines

Horological Machines are MB&F's main collection, started by Maximilian Büsser with HM1 in 2007. Each machine is a three-dimensional sculpture with a movement developed specifically for it, drawing on themes such as cars, aircraft and science fiction.

HM9 "Flow", introduced in 2018, has two balance wheels whose rates are averaged by a differential, in a streamlined case inspired by mid-20th-century car and aircraft design.
