IWC Portugieser - Tourbillon and Chronograph - Rose Gold - 43.5 MM - Blue Dial - IW394005

The Portugieser Tourbillon Rétrograde Chronograph is a testament to the allure of haute horlogerie, featuring the mesmerizing tourbillon complication. This "whirlwind" mechanism not only offers a captivating spectacle on the dial but also enhances timekeeping accuracy by mitigating the effects of gravity on the balance wheel's oscillations. Positioned prominently at "6 o'clock," the flying hacking minute tourbillon commands attention. Complementing this complication are a retrograde date display and a chronograph with a flyback function. Limited to just 50 pieces and exclusively available in IWC boutiques, this special edition boasts a nautical-inspired design in dark blue and gold. Crafted from 18-carat Armor Gold®, renowned for its exceptional hardness, the case exudes durability and elegance. The maritime theme continues with a blue dial and gold-plated hands and appliqués in 18-carat gold. Powering this timepiece is the self-winding IWC-manufactured 89900 calibre, offering a generous 68-hour power reserve. Enhanced with Diamond Shell® technology, the pallet lever and escape wheel ensure smooth energy transmission, further elevating the performance of this extraordinary watch.
