For most buyers choosing a Portugieser Chronograph, this is the one to focus on. The white dial with deep blue subdials and matching feuille hands delivers the clean, high-contrast look that defines the reference, while the polished 41mm steel case keeps it formal without feeling sterile. The blue alligator-pattern leather strap gives it a dressier character than sportier strap options. If you are deciding between photos and spec sheets, the details here matter because this watch lives or dies by dial balance, strap execution, and caseback presentation.
White and blue done the way this reference needs it
The appeal of the IW371620 starts with contrast. Here you get a bright white dial framed by a slim bezel, then two rich blue chronograph registers that immediately anchor the layout. The blue Arabic numerals and blue feuille hands keep the color story consistent without making the dial busy. On a Portugieser Chronograph, that balance is everything: wide open central space, clear minute track, and subdials placed low enough to preserve the elegant, elongated look collectors expect from the model.
This is also why the 41mm sizing matters. The Portugieser line needs enough diameter for the dial furniture to breathe, and that is exactly what this case size provides. You get the visual openness that makes the reference distinctive, rather than the compressed feel smaller chronographs can have.
The polished steel case keeps the watch formal
The case is offered in polished stainless steel, and that finish suits the watch. A Portugieser Chronograph should look refined from across the room, and the mirror-polished surfaces along the bezel, lugs, crown, and pump pushers do that work well. The profile is clean and traditional, with long lugs that give the watch its dress-chronograph stance.
For a buyer in this category, the case design is not just about shine. It is about proportion. The narrow bezel leaves maximum room for the dial, which is one of the key reasons this reference has such strong wrist presence even without a rotating bezel or added complications. If you want a chronograph that reads elegant first and sporty second, this case format is the right choice.
The strap choice changes the personality in the right direction
One of the most important details on this watch is the strap. The visible configuration is a blue alligator-pattern leather strap with matching blue stitching, and that choice gives the watch a more tailored character than a rubber setup would. It ties directly into the subdials, hands, and numerals, so the watch looks intentional as a full package rather than simply white-dialed with a blue accent.
That matters if you are comparing versions of the same Portugieser. A strap can shift the watch toward casual wear or toward business and evening use. This one clearly leans dressier, which is where the polished case and open dial design are strongest. If your goal is the classic Portugieser look under a cuff, this strap is part of the reason to choose this exact execution.
A display back and automatic chronograph movement add depth
Turn the watch over and the sapphire crystal case back gives you the mechanical side of the piece instead of a closed rear case. The automatic chronograph movement is visible through the display back, which adds a more complete ownership experience for anyone who enjoys the architecture of bridges, rotor engraving, and the extra visual motion that comes with an automatic caliber.
Up front, the watch uses a sapphire crystal with anti-reflective coating. That is especially relevant on a white dial chronograph because glare can flatten the dial and hide the depth between the main dial and registers. Here, the crystal specification supports what makes this reference attractive in the first place: legibility, contrast, and a cleaner view of the blue-on-white layout.
Who this IW371620 suits best
This watch makes the strongest case for itself if you want a chronograph that stays elegant. It is less about visual aggression and more about proportion, color discipline, and the unmistakable Portugieser dial architecture. The white dial keeps it versatile with tailoring, while the blue details stop it from feeling plain. The display back adds interest off the wrist, and the leather strap keeps the overall presentation aligned with the watch's formal roots.
For buyers deciding between several Portugieser variants, this is the reference to choose when the dial is the main event. The combination of white dial, twin blue registers, polished steel case, and blue leather strap gives you the classic look that makes this model instantly recognizable and consistently easy to wear.
