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.

GrandCliff TNT Royal Retro

The Dubois have been watchmakers for four generations. As well as trailblazers. Between Marcel Dépraz, son Roger, son-in-law Reynold Dubois, grandson Gérald Dubois, and great-grandsons Pierre, Pascal and Jean-Philippe (present directors of Dubois Dépraz), almost 50 patents have been registered in a century. And it is with his two brothers that Pierre Dubois, CEO of PIERRE DEROCHE, has developed the TNT Royal Rétro. The idea was born during one of those numerous and passionate discussions held around the family table: if today’s timepieces offer a triple retrograde reading of the seconds, why not go further and offer six retrograde hands? This required a movement that could house six mechanisms, remain unaffected by their velocity, and avoid any untimely stoppages. A feat that PIERRE DEROCHE has successfully achieved with the TNT Royal Rétro, which is to be unveiled at Baselworld 2009 !
