The IWC Portugieser Hand-Wound Eight Days Edition “75th Anniversary” (Reference IW510205) was released in 2015 to celebrate the 75-year legacy of the original 1939 Reference 325. This specific model is part of a limited run of 750 pieces in stainless steel, known for its "vintage-faithful" 43mm case and stark black dial.

• Case: 43mm diameter and ~12.5mm thickness, featuring a double-stepped bezel and a domed "box-shape" sapphire crystal that mimics vintage Plexiglas.

• Movement: Powered by the in-house manual-wound Caliber 59215, which offers a massive 192-hour (8-day) power reserve.

• Dial Design: Inspired by an art deco vintage model, it features a railroad-style minute track, traditional leaf-style (feuille) hands, and the historical "International Watch Co" script.

• Features: Includes a six o’clock date window, small seconds at 6 o’clock, and a power reserve indicator visible through the sapphire case back to maintain dial symmetry.

• Strap: Comes with a custom-made black alligator leather strap by Santoni, featuring a signature orange underside.
