Maximilian Busser and Friends, normally shortened down to MB&F, is a Swiss watch brand founded by Maximilian Busser in July 2005 and based in Geneva, Switzerland. The Horological Machines are MB&F’s first line of wristwatches. Their futuristic designs are inspired by science fiction and MB&F founder Maximilian Büsser’s childhood. The designs of MB&F’s Legacy Machines are retrofuturistic, with traditional analog faces and circular cases and unusual design elements including convex crystal and balance wheels suspended above the face with arches. In parallel with their collection of Horological Machines and Legacy Machines, MB&F have collaborated with selected artists to create “Performance Art” pieces, available as unique pieces or in limited editions. MB&F Performance Art pieces essentially see a MB&F Machine become the medium for the selected artist to paint or sculptures.
