Strong design codes and complicated mechanics confirm the TNT collection’s explosive character. Sculpted from steel and titanium, the TNT Chrono 43 brings a refined yet assertive presence to the wrist. This is the first time that functions have been displayed directly on a dial for a TNT watch - specifically a sapphire dial whose bold hour-markers and transparent openings envelop the hands to confirm the overall force of the piece.

The automatic chronograph movement by Dubois Dépraz is partly openworked with stripped-down bridges and the hallmark Pierre DeRoche 60-minute counter with red indicators. A red central chronograph seconds hand completes the motorsport-inspired look. Mounted on a stitched rubber strap, the TNT Chrono 43 is the brand’s eighth chronograph. This 201-piece limited series has already established Pierre DeRoche as a true specialist in time measurement.


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. A contemporary vision of transparency with its dramatic openworked dial and raw functionality, the TNT Chrono 43 brilliantly mingles aesthetic virtuosity, innovation and originality. Its design stems from a quest for perfect balance, reflecting the chemistry between the couple.
