MB&F (Maximilian Busser & Friends) is a Swiss independent watchmaking concept laboratory founded in 2005 by Maximilian Busser in Geneva, Switzerland. The brand operates as an artistic and creative collective rather than a traditional watch manufacturer, collaborating with independent watchmakers, engineers, and artisans to produce unconventional timepieces.
Maximilian Busser, who previously served as managing director of Harry Winston's watch division, founded MB&F to create watches that function as three-dimensional mechanical sculptures. The brand's output is divided into two primary lines: the Horological Machines (HM) series, featuring organic and sculptural case designs often inspired by automotive, aeronautical, and science fiction themes, and the Legacy Machines (LM) series, which reinterprets classical watchmaking complications in round cases with prominent balance wheels displayed on the dial side.
Notable creations include the HM4 Thunderbolt (inspired by aviation), the HM6 Space Pirate (featuring a retractable shield over the tourbillon), the HM9 Flow (air-intake-inspired twin balance wheels), and the LM Perpetual (a perpetual calendar designed by Stephen McDonnell). MB&F also produces collaborative objects with L'Epee 1839, including desk clocks in forms such as robots, octopuses, and spacecraft.
All MB&F movements are developed in-house in collaboration with specialist independent watchmakers. The brand produces fewer than 300 watches per year across its various models. MB&F operates the M.A.D.Gallery (Mechanical Art Devices) exhibition spaces in Geneva, Dubai, Taipei, and other cities.
Retail prices typically range from approximately $50,000 to over $500,000, depending on the complexity and materials of each piece. MB&F timepieces are available through the brand's own galleries and a select network of authorized retailers.
