Zenith Grande Class Tourbillon watch

The Zenith Grande Class Tourbillon watch is a prestigious luxury timepiece with a unique presence. Equipped with an exclusive Manufacture movement and rare complications, this Zenith watch displays a distinctive style that underscores the technical brilliance it embodies. Crafted exclusively in 18K gold, the classically-sculpted Class watch case measures an impressive 45mm in diameter. Key characteristics of this elegant design include extremely fine finishing to each component of the case, including the flat polished bezel that merges perfectly with the gently domed sapphire crystal. The dial of this watch is unmistakable; from the center of the tourbillon cage, outward rays of "light", crafted from polished gold, stream from the Zenith star, symbolizing the shining horological excellence of this famous brand. Such a design is not accidental, for the Zenith Grande Class Tourbillon showcases the most coveted complication in the realm of traditional watchmaking. First invented at the turn of the 19th century, the tourbillon and its continuously rotating cage has remained a benchmark of horological skill and dedication to artisanal values. The self-winding Zenith El Primero 4035 caliber movement is exceptional, even among fine tourbillon movements. With a proud heritage dating back to the late 1960's, the balance wheel of this mechanism pulses at the extraordinary pace of 36,000 alternation per hour, thus making it the highest frequency tourbillon escapement ever made. In addition to the fascinating and mysterious tourbillon device, the Zenith Grande Class Tourbillon watch also shows off a chronograph mechanism with 12-hour and 30-minute counters. As is the case with all Zenith El Primero movements, the chronograph mechanism utilizes a column wheel to control its operations, and its construction is fully integrated. A sapphire crystal window in the caseback permits a full view of the fascinating mechanics of this exclusive movement, which is equipped with a guilloche-decorated 22K gold rotor. The Zenith Grande Class Tourbillon watch is presented in both 18K rose gold and 18K white gold. The 18K rose gold watch shows off a silver-plated solid gold dial with a finely executed guilloche pattern in the center, while the white gold version has a solid gold dial which has been given a smooth, matte black finish. A hand-crafted alligator strap with a triple deployant gold folding clasp completes this complex Zenith timepiece, which is limited to an edition of only 25 pieces for each metal.
