MB&F - Maximilian Busser & Friends - is an independent Swiss watchmaker founded in Geneva in 2005 by Maximilian Busser, the former managing director of Harry Winston Rare Timepieces. It produces roughly 300 watches a year across two families: the Horological Machines, which abandon conventional watch form entirely, and the Legacy Machines, which reinterpret nineteenth-century watchmaking in round cases. MB&F has no in-house factory in the traditional sense - it credits the independent watchmakers, designers and suppliers who build each calibre by name, and also produces mechanical clocks in co-creation with L'Epee 1839.
