Pierre DeRoche - TNT Royal Retro 43 Diablo

New Highlights from Pierre DeRoche!

A marvel of technicality, originality and sportiness, the Pierre DeRoche TNT Royal Retro and the balletic dance of its six retrograde second hands have fascinated watch freaks for more than a decade. The latest incarnation of this unique complication, the TNT Royal Retro 43 Diablo, pushes the limits of watchmaking expertise even further and reveals a fiery temperament.

The lightness of the TNT Royal Retro 43 Diablo is lent gravitas by its powerful lines. Its exclusive complication is housed in a 43 mm steel and titanium case that affirms its technicality. The bezel is made from itr2, a hypoallergenic composite based on carbon nanoparticles that is six times lighter than steel and four times lighter than titanium. The DLC-coated black bridges contrast with the complication’s 5N gilded gear train and racks and the red hands.

Lastly, the textured leather strap offering the alternative between the symbolically devilish colours of red or black brings the final smouldering touch to this exceptional watch issued in a limited edition of 101 pieces worldwide.
