Love and passion are the cornerstones of Pierre DeRoche, the brand from the Vallée de Joux that is preparing to celebrate Valentine’s Day in step with the seconds ticked off on the Royal Retro.
Pierre and Carole Dubois - the founders of Pierre DeRoche - met during their studies and have been married for 28 years. Time flies, but their love grows bigger, stronger and more harmonious than ever – a balance reflected in the movements of their watches.
The Dubois family, a watchmaking dynasty already spanning four generations, has developed a unique timepiece in its TNT collection, named Royal Retro. Minutes are counted off by six successive retrograde seconds hands. Its secret is revealed by its dial-free face.
Like a central force, a carrier drives – for six 10-second periods each – a series of wheels that activate a rack. The latter pivots on a jewel and acts on the strip spring, which becomes taut as it moves slightly. It resists for ten seconds before the carrier disengages. The retrograde seconds hand then returns to its initial position and passes the baton on to the next one… and so on.
Both watches are equipped with a mechanical automatic and exclusive Dubois-Depraz calibre. It features a decorated and engraved rotor, chamfered central bridges and 6 chamfered, satin-finished seconds bridges. The watches display the hours, minutes, seconds - with retrograde function in six 10-seconds sectors - and the date.
On the 42,5mm steel case of the feminine model, the bezel is set with 64 diamonds (1,28 cts). The case of the masculine watch measures 47,5mm and is made of black PVD-coated titanium and steel.
