About the Horological Machine family

The Horological Machines are MB&F's founding collection, starting with HM1 in 2007. Each is a three-dimensional sculpture with a distinct theme, from spacecraft and jet engines to frogs, racing cars and a bulldog, and they often display the time in unusual ways, such as on rotating cones or through prisms.

The catalog includes many references across the series, in titanium, gold and other materials, each usually made in a limited run of a given material and colour. Buyers expect the full set and elaborate box, the edition number and a service history from MB&F, and every display should be checked for correct function.
