The Basics

Horological Machine N°2.2, affectionately called ‘Black Box’, is the result of a collaboration between Max Büsser (and friends) and noted watch designer Alain Silberstein. The latter is best known for his use of bold colors and geometrical shapes. Built on the HM2 platform, the Black Box is a subtle reminder of these signature touches, while having a look that is unique yet distinctively MB&F. Presented in November 2009, Horological Machine N°2.2 “Black Box” is a limited edition of 8 pieces and is sold out.
