Brand New, Pierre DeRoche TNT Chronograph “Penta” Flyback – Rose Gold · Steel · Titanium
A Swiss rarity — complex chronograph
*****


An extraordinary opportunity — For collectors and connoisseurs of haute horlogerie, this chronograph is one of the most exclusive, limited to only 21 pieces worldwide.

Independent Swiss watchmaking from the Vallée de Joux, founded by Pierre Dubois and deeply connected to Dubois-Dépraz, one of the world’s foremost creators of high-end complications with over a century of expertise.

The TNT Chronograph “Penta” takes its name from the five discs that define its openworked dial — two for the big date, and three for the chronograph functions (seconds, 60-minute, and 12-hour counters). This unique architecture offers a bold, sporty, mechanical aesthetic.

Equipped with a flyback chronograph, the watch allows stopping, resetting, and restarting the chronograph in one single action — a feature historically prized in aviation. Combined with the oversized big date display, this is a rare blend of design, complexity, and functionality.
