Brand New, Pierre DeRoche TNT Chronograph “Penta” Flyback – Steel · Titanium A Swiss rarity — complex chronograph with big date, now offered exclusively on Catawiki ***** An extraordinary opportunity — Pierre DeRoche timepieces have never before been offered in a public sale with this unique “No Reserve” format. For collectors and connoisseurs of haute horlogerie, this chronograph is exclusive, limited to 201 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. ***** Model Information Model: TNT Chronograph “Penta” Flyback Big Date Reference: TNT10006ACTI0-001CRO Limited Edition: 201 pieces (Pictures are illustrative; unique numbers may differ) Condition: Brand New – Current Collection Including: 2 Years International Warranty – Papers – Original Box Movement and Functions Movement: PDR 4012, Self-winding mechanical, exclusive Dubois Dépraz calibre 44512 Diameter: 34.60 mm · Thickness: 8.45 mm Frequency: 4 Hz (28,800 vibrations/hour) Jewels: 49 Power reserve: 42 hours Rotor: Circular monometal oscillating weight, engraved and decorated, mounted on ball-bearings Bridge: Large date bridge decorated with Côtes de Genève Functions: – Hours, minutes, seconds (small seconds disc) – Big Date – Flyback Chronograph: central seconds + 60-minute and 12-hour counters via discs – Stop-seconds for precision setting Special Feature The TNT Chronograph “Penta” stands out through its five-disc dial design and the flyback function, offering both mechanical theatre and practical precision.
