Pierre DeRoche TNT Royal Retro

Pierre DeRoche has created the first movement able to house six retrograde seconds mechanisms. While this complication has been introduced to provide an element of fun, it also reveals a totally original approach: all the retrograde hands in this model are driven by gears rather than cams and, thanks to a strip-spring that has replaced the classical balance-spring system, return to their initial positions after “passing on the baton” to the next retrograde hand. This innovation facilitates adjustment and enhances shock resistance. Limited edition of 21 pieces.
