PIERRE DEROCHE – GrandCliff TNT Royal Retro

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.
