Defy Extreme Double Tourbillion 45 mm, titanium with black rubber strap, self-winding caliber El Primero with chronograph function and tourbillion | Reference Number ZN100017

Maximum robustness meets the finest watchmaking skills and the highest precision. The 45-millimeter carbon and rose gold case of the Defy Double Tourbillon (Ref. 12.9100.9020/78.I200) houses an EL Primero movement with a double tourbillon, which is already visually very impressive. In addition, the movement's typical functions of the 30- and 60-minute counters, the chronograph power-reserve display and the possibility of stopping time to 1/100th of a second are retained and ensure a range of functions that, in full action, are a true spectacle. The skeletonized dial exposes all of this to the naked eye at every glance, while still appearing uncluttered with its subtle rose gold accents. A color-coordinated black rubber bracelet completes the fascinating design of this watch, which is water-resistant to 200 meters. With this extraordinary timepiece, Zenith once again proves that they master haute horlogerie like almost no other brand.
