HM4 is an automatic movement manufactured by MB&F, introduced in 2010. Designed by Jean-Marc Wiederrecht of Agenhor, it features a distinctive aviation-inspired case with a structure resembling a jet engine and two separate dials—one displaying time horizontally and another showing power reserve vertically, styled after oil pressure gauges. The movement reflects MB&F's radical design philosophy for the Horological Machine series. Production has been discontinued.
