Pierre DeRoche TNT Royal Retro RB LE watch


The new Pierre De Roche TNT Royal Retro RB may look a trifle busy, and that’s because it is. No less than 6 retrograde seconds hands are busy, busy busy whirring round the face of the watch at intermittent intervals, counting the passing of time in a constant relay of ten seconds. Endlessly fascinating to watch, and no doubt exquisitely intricate to create.



It’s even busier under what would normally be the dial of the watch, for there isn't a dial to speak of, all the complex mechanisms in the making of the timepiece are clearly visible. There is also a bridge with 12 pivots and 6 chamfered, satin-finished seconds bridges.  Each of the seconds hands is gear-driven, the traditional balance-spring having been replaced by a strip-spring mechanism which sends each back to its original position retrospectively.

This new edition of the watch comes with a rubber bezel on a 47.5mm titanium case. The Royal Retro is powered by an exclusive Dubois Dépraz Calibre, a manufacture which takes movements by ETA,  Sellita and others and then adds their own unique complications.

In fact Dubois Dépraz discreetly supply calibres to some of the best names in the industry. A family business for more than 110 years, brothers Pascal and Jean-Philippe Dubois continue the watchmaking traditions started by their great grandfather in 1901.

As for the watch brand itself, there is a strong family link between Dubois Dépraz and Pierre De Roche. Pierre is a brother to Pascal and Jean-Philippe Dubois, hence the ability to call on such an exclusive manufacture of specialised movements.

The new TNT Royal Retro is in a limited edition of just 201 pieces and comes on a high quality rubber strap with clasp.
