The RM 004 is one of the new generation of chronograph design in the most inspiring and challenging watch category. Its characteristics embody the rugged mechanical beauty of F1, unique performance characteristics and exceptional rarity.
The RM 004 calibre is made up of an astounding 383 components of which 230 are totally unique. A number of these parts cannot even be seen with the naked eye. This makes it an extremely complicated movement in terms of parts control (trueness of dimensions to specifications), finishing, polishing, assembling and adjusting. Technically, the movement of an RM 004 represents a challenging and quite delicate work.
Assembling the movement is highly complicated and there are only a few watchmakers who have the knowledge and experience to carry out this work. That is why only a few RM 004 were built each year.
