IWC Portugieser Chronograph automatic silver dial leather strap 41 mm

A Legend Born in 1939, an Icon Since 1998

Among all the watches produced by IWC Schaffhausen, few enjoy a reputation comparable to that of the Portugieser Chronograph. Its story traces back to the late 1930s, when two Portuguese importers asked the Swiss manufacture to develop a wristwatch offering the precision of the marine navigation instruments used aboard ships. To meet this challenge, IWC adapted a pocket watch movement to a large wristwatch case, giving birth to the renowned Reference 325.

The decades that followed transformed this unconventional creation into a true horological icon. After its revival in the 1990s, the Portugieser collection entered a new era with the introduction of the Chronograph Rattrapante in 1995, and most notably with the launch of the Portugieser Chronograph Reference 3714 in 1998. Its perfectly balanced dial, timeless elegance, and remarkable versatility quickly established it as one of the most iconic models in the IWC catalogue.

The IW371604 belongs directly to this prestigious lineage. Introduced as part of the 3716 generation unveiled in 2020, it faithfully preserves the design that made the 3714 successful for more than twenty years. IWC deliberately chose to maintain the model’s proportions, dial architecture, and visual identity, focusing its efforts on mechanical improvements instead. A rare approach in contemporary watchmaking that highlights the timeless character of a creation that has become a benchmark among dress chronographs.

A Bicompax Dial Considered a Benchmark of Balance

If there is one feature that has contributed to the success of the Portugieser Chronograph for more than twenty-five years, it is undoubtedly its dial. Often regarded as one of the most harmonious chronographs in contemporary watchmaking, it captivates with its exceptional legibility and perfectly judged proportions. Every element seems to occupy exactly the right place, creating a sense of balance that is rarely matched.

The IW371604 faithfully reproduces this now-iconic architecture. The 30-minute counter positioned at 12 o’clock perfectly complements the small seconds display at 6 o’clock, while the applied Arabic numerals and elegant feuille hands enhance the refined character of the model. Unlike many contemporary chronographs, no date display disrupts the symmetry of the dial, allowing the composition to retain an exceptional sense of visual purity.

Surrounding the dial, the famous railway-track minute scale directly recalls the navigation instruments that inspired the earliest Portugieser models. The quarter-second scale on the flange adds a more technical dimension, enabling particularly precise timing measurements while introducing a subtle sporting touch to the overall design.

This unique combination of functionality, restraint, and elegance explains why the Portugieser Chronograph has become an essential reference in the world of dress chronographs. More than twenty years after its introduction, its dial remains a true masterpiece of watch design, admired by both collectors and industry professionals alike.

The Manufacture Calibre 69355 and the Column Wheel

While the design of the Portugieser Chronograph remained virtually unchanged during its evolution into the 3716 reference, the true revolution lies within the case. In 2020, IWC decided to equip its iconic chronograph with a modern manufacture movement, further reinforcing the status of this indispensable reference within the collection.

Visible through a transparent sapphire crystal case back, the manufacture calibre 69355 belongs to the family of chronograph movements developed by IWC in Schaffhausen. Designed to deliver robustness, precision, and reliability, it features an integrated architecture with a column wheel—one of the most prestigious solutions in traditional watchmaking for controlling chronograph functions.

This construction ensures exceptionally smooth pusher operation. Starting, stopping, and resetting the chronograph can be performed with remarkable precision and fluidity, providing a mechanical experience particularly appreciated by chronograph enthusiasts.

The automatic winding system delivers a power reserve of approximately 46 hours, while the movement’s architecture has been designed to be admired through the sapphire case back. Carefully decorated bridges, the column wheel, and the openworked oscillating weight showcase the manufacture’s expertise and add a new dimension to this Portugieser Chronograph.

This evolution is arguably the most significant improvement introduced to the collection since the launch of Reference 3714 in 1998. By preserving an iconic design while adopting a modern manufacture movement, IWC has successfully evolved the watch without ever betraying its identity.

The Timeless Elegance of the Silver and Gold Dial

The IW371604 is often regarded as one of the most classical and elegant expressions of the Portugieser Chronograph. Its silver-plated dial provides a luminous backdrop for the gold-toned feuille hands and matching appliqués, creating a particularly refined visual harmony. This color combination transcends decades without ever losing its appeal, contributing significantly to the model’s timeless character.

The slim bezel also plays a crucial role in the watch’s balance. By minimizing the visual footprint of the case, it allows the dial to take center stage—a historic signature of the Portugieser collection. This wide opening enhances legibility while giving the watch a remarkable presence on the wrist despite its perfectly controlled proportions.

The black alligator leather strap adds a touch of contrast that highlights the dial’s natural elegance. Combined with the polished surfaces of the stainless steel case, it gives the watch a personality that is both sophisticated and understated. This rare versatility explains why the Portugieser Chronograph feels equally at home with a tailored suit as it does with more casual attire.

More than twenty-five years after its introduction, this aesthetic architecture remains remarkably modern. Far removed from fleeting trends or passing fashions, the Portugieser Chronograph IW371604 continues to embody a vision of elegance based on balance, legibility, and purity of design.

The Portugieser Chronograph in Its Most Accomplished Form

The Portugieser Chronograph IW371604 represents the culmination of a formula that has become iconic in contemporary watchmaking. A direct descendant of the legendary Reference 3714, it retains everything that made the original model so successful: exceptional legibility, timeless elegance, and an instantly recognizable identity.

The introduction of the manufacture calibre 69355 and the transparent sapphire case back marks a major evolution without altering the very essence of the watch. IWC chose to refine its creation rather than reinvent it, a decision that reflects the maturity and enduring relevance of the original design.

With its silver-plated dial accented by gold details, its now-iconic bicompax architecture, and its modern column-wheel movement, this Portugieser Chronograph remains one of the essential references for enthusiasts of dress chronographs. A watch that transcends generations with the same elegance and that continues, more than twenty years after its creation, to embody horological excellence according to IWC.
