IWC Portugieser Hand-Wound Tourbillon Anniversary Edition

A hand-wound tourbillon timepiece combining the timeless modern design of the Portugieser collection with a flying minute tourbillon at 6 o’clock. Gilded Arabic numerals and gold leaf-shaped hands harmonize beautifully with a silvery-plated dial. Features include: 1) In-house developed Caliber 81905 movement with 72-hour power reserve, faithfully replicating the three key functions of the original. 2) Case meticulously crafted in 1:1 proportion to the authentic model, precisely matching the three-part construction, beveled edges, and curved satin-brushed finishing on both front and back; 42mm in diameter, 11mm in thickness. 3) Domed sapphire crystal. 4) Hands precisely replicated through extensive prototyping and molding processes to achieve the exact three-dimensional form of the original. 5) Strap made of Italian calf leather with crocodile texture, hand-stitched for refined detail, paired with an IWC-original folding clasp featuring crisp engravings that mirror the authenticity down to the finest details.
