IWC Portugieser - Tourbillon and Chronograph - Platinum - 43.5 MM - Silver Dial - IW394006

The Portugieser Tourbillon Rétrograde Chronograph stands as a pinnacle of haute horlogerie, showcasing the mesmerizing tourbillon complication. This intricate "whirlwind" mechanism, where the balance wheel rotates within a cage, not only captivates with its visual allure but also enhances timekeeping precision by counteracting the effects of gravity on the oscillating system. Positioned prominently at "6 o'clock," the flying hacking minute tourbillon commands attention, complemented by a retrograde date display and a chronograph with a flyback function. Limited to just 50 pieces, the case of this exceptional timepiece is crafted from platinum, exuding an aura of exclusivity and luxury. The silver-plated dial and rhodium-plated hands and appliqués harmonize beautifully with the rare precious metal. Powering this masterpiece is the self-winding IWC-manufactured 89900 calibre, boasting a remarkable 68-hour power reserve. Enhanced with Diamond Shell® technology, the pallet lever and escape wheel ensure smooth energy transmission, further enhancing the performance and longevity of this extraordinary watch.
