With the 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 toothed gears rather than smooth cams, and thanks to a strip-spring that has replaced the classic balance-spring system, they return to their initial positions after ‘passing on the baton’ to the next retrograde hand. This innovation facilitates adjustment and enhances shock resistance.

The bold and industrial case has been created to showcase a variety of details at any given angle, and the delicately adorned Dubois Dépraz automatic movement with its engraved rotor is visible through the caseback. The mechanically open movement, with central handset is clear and legible, whilst exposed construction and jewels along with open gearing continues the industrial aesthetic across the top side of the watch. Like all models in the TNT Royal Retro 43 range, it is a limited edition of 201 pieces.


In celebration of Carole and Pierre’s long-standing relationship, the Pierre DeRoche TNT collection plays on the idea of a couple - a yin and a yang - working together perfectly in harmony. The subtle balance and relationship between power and delicacy that regulates the passage and accuracy of time is shown every 10 seconds via the retrograde hands, which work independently, and yet, in total synchronicity.
