IWC Portugieser Chronograph automatic dune dial leather strap 41 mm

An iconic chronograph reimagined

The Portugieser Chronograph has become one of IWC Schaffhausen's defining timepieces. Inspired by the precision of the original marine chronometer-based Portugieser watches, it combines timeless design with exceptional legibility and perfectly balanced proportions. Reference IW371624 continues this legacy while introducing the latest aesthetic refinements that define the modern Portugieser collection.

A captivating Horizon Blue dial

The striking Horizon Blue dial immediately sets this model apart. Produced using an elaborate multi-layer lacquering process, it delivers exceptional depth and changing reflections depending on the light. Applied Arabic numerals, rhodium-plated feuille hands and the signature railway-track minute scale reinforce the unmistakable Portugieser identity, while the recessed chronograph minute counter and small seconds display create a perfectly balanced layout.

The IWC manufacture calibre 69355

Powering this timepiece is the IWC-manufactured calibre 69355, an automatic column-wheel chronograph movement developed and assembled in Schaffhausen. Renowned for its reliability, precision and smooth chronograph operation, it beats at 28,800 vibrations per hour and provides a 46-hour power reserve. The sapphire crystal case back reveals the beautifully finished movement, showcasing the Manufacture's outstanding engineering and craftsmanship.

Designed for everyday elegance

The polished 41 mm stainless steel case offers refined proportions and exceptional comfort on the wrist. A double box-shaped sapphire crystal with anti-reflective coating enhances the visual depth of the dial while ensuring excellent readability. Completing the watch is a blue calfskin leather strap fitted with the EasX-CHANGE® system, allowing effortless strap changes without tools.

Contemporary watchmaking excellence

The Portugieser Chronograph IW371624 perfectly reflects IWC Schaffhausen's philosophy of combining timeless aesthetics with mechanical excellence. Its manufacture chronograph movement, sophisticated Horizon Blue dial and elegant proportions make it an exceptional choice for collectors seeking a refined yet highly capable luxury chronograph.
