IWC Portugieser Chronograph automatic silver dial leather strap 41 mm

A Legend Born in 1939, an Icon Since 1998

The story of the Portugieser began in the late 1930s when two Portuguese importers asked IWC Schaffhausen to create a wristwatch capable of delivering the precision of marine navigation instruments. To meet this challenge, the manufacture adapted a pocket watch movement to a large wristwatch case, giving birth to the legendary Reference 325. With its clean dial, exceptional legibility, and proportions unlike anything seen at the time, the Portugieser laid the foundations for what would become one of the most important collections in Swiss watchmaking.

Its true breakthrough came in 1998 with the introduction of the Portugieser Chronograph Reference 3714. Its perfectly balanced aesthetics, symmetrical bicompax layout, and timeless elegance immediately captivated enthusiasts of classic watches. Over the years, the model became one of the cornerstone references of the IWC catalogue and one of the most recognizable dress chronographs on the market.

The IW371605 continues this legacy through the 3716 generation unveiled in 2020. Remaining faithful to IWC’s philosophy, it preserves the design that made its predecessor such a success while benefiting from major mechanical upgrades. This approach allows the Portugieser Chronograph to remain a benchmark within its segment while retaining the identity that forged its legendary status.

The Silver and Blue Dial, Signature of the Modern Portugieser

If there is one configuration instantly associated with the Portugieser Chronograph today, it is undoubtedly the silver-plated dial paired with blue hands and appliqués. Over the years, this combination has become a true aesthetic signature of the collection, perfectly embodying the balance between classic elegance and modernity.

The IW371605 showcases this contrast with remarkable refinement. The silver-plated dial offers a natural luminosity that enhances the depth of the recessed subdials positioned at 12 and 6 o’clock. The blue feuille hands and applied Arabic numerals add a distinctive touch of character while ensuring outstanding legibility.

As on the historic models, the famous railway-track minute scale frames the dial harmoniously. The quarter-second scale on the flange recalls the instrumental origins of the Portugieser and allows particularly precise timing measurements. The absence of a date display further preserves the purity of the design and reinforces the symmetry that has made the model so renowned.

This perfectly balanced visual architecture explains why the Portugieser Chronograph is often regarded as one of the finest chronographs in contemporary watchmaking. In this silver-and-blue execution, it arguably reaches one of its most iconic expressions, combining restraint, refinement, and personality in a remarkably coherent design.

The Manufacture Calibre 69355 and the Column Wheel

Beneath the timeless design of the Portugieser Chronograph IW371605 lies a major evolution introduced by IWC in 2020. While the manufacture deliberately preserved the aesthetics of the model, it thoroughly modernized its mechanics by integrating the manufacture calibre 69355, visible through a transparent sapphire crystal case back.

Developed and produced by IWC, this automatic chronograph movement belongs to the 69000 calibre family, designed to provide robustness, precision, and reliability in everyday use. Its architecture is built around a column wheel, a traditional solution highly appreciated by chronograph enthusiasts for the precision and smoothness it provides when operating the pushers.

Each activation of the chronograph is therefore characterized by a crisp and precise mechanical feel. The start, stop, and reset functions operate with exceptional smoothness, reflecting the care invested in the movement’s design.

The calibre 69355 offers a power reserve of 46 hours and beats at a frequency of 28,800 vibrations per hour. Visible through the sapphire case back, it reveals a carefully executed architecture dominated by an elegant openworked oscillating weight and refined finishing worthy of a movement designed to be admired.

This mechanical upgrade represents one of the most significant improvements introduced to the Portugieser Chronograph since its launch in 1998. By combining a modern manufacture movement with a design that has become iconic, IWC has further strengthened the appeal of a watch that ranks among the great references of the contemporary dress chronograph.

A Dress Chronograph with Timeless Elegance

The Portugieser Chronograph IW371605 perfectly illustrates IWC’s ability to create a watch that is both sophisticated and easy to wear. Thanks to its balanced proportions, exceptionally legible dial, and absence of unnecessary elements, it retains a natural elegance that transcends trends and generations.

The 41 mm stainless steel case is enhanced by an exceptionally slim bezel, one of the historical signatures of the collection. This construction allows the dial to take center stage in the overall design and reinforces the sense of openness that has characterized the Portugieser since its inception. Despite its strong presence, the watch maintains remarkable visual refinement on the wrist.

The blue alligator leather strap beautifully echoes the shades of the hands and appliqués. This chromatic consistency contributes greatly to the refined character of the IW371605 and gives it an immediately recognizable personality. More contemporary than versions featuring gold accents, it nevertheless retains all the nobility and elegance associated with the collection.

This ability to combine classical aesthetics with modern appeal explains why the Portugieser Chronograph has become a benchmark among dress chronographs. Elegant without being ostentatious and technical without being demonstrative, it embodies a vision of luxury based on balanced proportions and exceptional execution.

The Portugieser Chronograph in Its Most Iconic Form

Among all versions of the Portugieser Chronograph, the IW371605 is arguably the one that most faithfully expresses the contemporary identity of the collection. Its silver-plated dial accented with blue details has, over the years, become a true visual signature for IWC, instantly recognizable to watch enthusiasts around the world.

It brings together all the ingredients that have made the model such a success: a perfectly balanced bicompax dial, outstanding legibility, a modern manufacture column-wheel movement, and timeless elegance rooted in more than eight decades of history. Every detail reflects IWC’s commitment to preserving a design that has become iconic.

More than just a chronograph, this Portugieser is now an essential reference in contemporary watchmaking. A watch capable of accompanying its owner throughout a lifetime without ever losing its relevance or its power of attraction.
