The Horological Machines 55.ZL.B, seen from the bench

The Horological Machine N°5 HM5 is a kinetic wrist sculpture by Maximilian Büsser & Friends, featuring an avant-garde three-dimensional architecture that challenges traditional watchmaking. This timepiece combines aerospace materials and complex mechanical systems in a unique design that explores impossible forms and sculptural geometry at the wrist.
