TNT Chrono 43

Powerful designs and complex mechanics confirm the TNT collection's explosive character. Sculpted from steel and titanium, the TNT Chrono 43 nonetheless brings a subtle classicism to the wrist. This is the first time in the TNT collection that functions are displayed on a dial, specifically a sapphire dial whose bold hour-markers and transparent openings envelop the hands to confirm the overall force of the design. The brand's values are clearly in evidence, exemplified in the 60-minute counter, a hallmark of Pierre DeRoche, and the visible mechanism, an automatic chronograph movement by Dubois Dépraz. 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.

Pierre and Carole, a love story

In watchmaking as in love, the most beautiful stories are entwined with passion that endures through time. The secret? A subtle interaction between each element to allow the magic to weave its unique spell. While implacably mathematical when it comes to orchestrating tiny mechanical parts, this magic is mysterious and elusive when it comes to stirring the hearts of a man and a woman. For Carole and Pierre Dubois, founders and owners of Pierre DeRoche, everything began more than 30 years ago. When they first met they had the sense of having known each other forever, and have never been parted since.

Horological inheritance

Life has that funny way of delivering unexpected surprises. On paper, nothing predestined them for this amazing story. Carole was a laboratory assistant, while Pierre had been immersed since childhood in the science of time measurement. In the Dubois family, firmly established in the Vallée de Joux, watchmaking is a heart-felt vocation passed on from father to son. Across four generations already, the Dubois-Dépraz family had been developing and producing horological complications for the great names in Swiss watchmaking. This love of fine mechanisms proved catching. Carole succumbed to the charms of a previously unknown world, to the point of sharing Pierre’s dream: to create a full-fledged watch brand. It would be their fourth child and the Pierre DeRoche adventure began in 2004.

A technical and daring brand

The youthful brand was not short on creativity. Firstly, on a mechanical level, with complications that are unique in the world. The chronograph with three concentric hands on a single counter, as well as the fascinating ballet of the TNT Royal Retro orchestrated by six retrograde seconds hands are perfect examples. Carole and Pierre have indeed made moving off the beaten track their leitmotif. Their timepieces are unlike any others, brilliantly mingling aesthetic virtuosity, innovation and originality. Each watch stems from a perfect balance reflecting the chemistry between the couple.
