A standard watch with a power reserve of 48 hours requires between 20 and 30 full turns of the crown to be fully wound. With HM11, its 96 hours of power reserve can be completely rewound after just 10 full clockwise rotations of the case.
Relocating the winding action from a small-diameter component like a crown to the case itself also raises the upper limit of torque you can apply to the winding mechanism. It’s simple physics — increasing the diameter of a rotating element reduces the energy required to turn it. This means that the mainspring barrel of HM11 Architect can be rewound more directly and more quickly.
The “bubble houses” of the mid- to late 20th century were enabled by evolutions in building technology, using materials and methods that seemed wildly implausible at first — or at least until someone actually made a house with one. And so, it is with the MB&F Horological Machine Nº11 Architect. New things often require new ways. True change starts when you think differently, but it endures when you live differently.
Despite its 3-dimensional, architectural conception and the complexity of its movement, the HM11 case surprisingly measures only 42mm in diameter. It sits sleekly and comfortably on the wrist, thanks to the curved case feet that are also the strap attachment points. These allow the watch to fit a variety of wrist sizes – and also provide stability when the case is turned to wind the barrel.
After decades conforming to the rules of corporate watchmaking, Max Büsser broke the chains and started a rebellion in 2005; a rebellion called MB&F - Maximilian Büsser & Friends.
MB&F is an artistic concept laboratory based around a simple idea: to assemble collectives of independant watchmaking professionals to develop radical watches - Horological or Legacy Machines. By nurturing teams of talented individuals, harnessing their passion and creativity and crediting each person's essential role, MB&F uses their synergy to become much greater than the sum of its parts. Respecting tradition, but never constrained by it, MB&F reinterprets traditional, high-quality watchmaking into three-dimensional kinetic sculptures.
When it comes to HM11, post-modernism architects, some of whom eschewed that title and instead called themselves habitologists, built houses which appeared as if they had been exhaled out of the earth, or as if the land had flexed its fingers and forgotten to curl them fully back up again. They bubbled, they undulated, they arched like an extended sinew. And when Maximilian Büsser, founder of MB&F, looked at one of these houses, he thought, “What if that house was a watch?”
