Pierre DeRoche the TNT Royal Retro Power Reserve


Pierre DeRoche offers a new interpretation of its iconic TNT Royal Retro model enriched with a power reserve. The spectacular complication thus makes way during a full 20 seconds for the elegant mechanism of the new function positioned at 6 o’clock. The four remaining retrograde seconds mechanisms are nonetheless enough to give this timepiece unique character and to display the avant-garde talent of the watchmaker from the Vallée de Joux. Loyal to the TNT spirit, the movement, and notably the four power-reserve wheels, are entirely visible and magnificently decorated. A fine mechanical blend of strength and delicacy.
