Frequently asked questions

What is the lug width of the IWC Portugieser IW3714-61?

The IWC Portugieser IW3714-61 features 20 mm lugs. This measurement refers to the distance between the two spring bars (metal pins) that anchor the strap to the case. To verify compatibility correctly, measure the distance between the pins in millimetres: it must be exactly 20 mm. The pin diameter for this reference is 18 mm, which is standard for the classic Portugieser family.

What is the best strap for the IWC Portugieser IW3714-61 in rose gold?

For the IW3714-61 in rose gold, we recommend vegetable-tanned alligator in dark brown, cognac or tobacco tones. This choice enhances the warmth of rose gold without aesthetic competition. Alternatively, vegetable-tanned calf leather in deep burgundy or mahogany brown creates an elegant chromatic continuum. The fine grain of alligator does not distract from the readability of the lacquered dial, which is fundamental for this classical reference.

How do you change the strap on an IWC Portugieser IW3714-61?

Changing the strap requires a spring bar tool (a specific tool to release the pins). Position the tool on the lateral hole of the spring bar, press gently downward to eject the pin from the left lug, and remove the strap. For insertion, align the new strap's pins with the case lugs, press until you feel a secure click (it must be firmly seated). Verify that the strap is symmetrical and free of twists. If you are inexperienced, entrust the task to a watchmaker to avoid scratches on the rose gold case.

Can I use an aftermarket strap on the IW3714-61?

Yes, any strap with 20 mm lugs and 18 mm diameter pins is compatible with the IW3714-61. Quality aftermarket straps—such as those in alligator, calf or shell cordovan from certified artisans—can further enhance the watch compared to the factory strap. Ensure that the thickness of the strap terminals does not exceed 1.8 mm for installation without force. Avoid inferior-quality straps that could scratch the rose gold during assembly.

How long does a leather strap last on an IWC Portugieser IW3714-61?

A quality vegetable-tanned leather strap (alligator or calf) lasts an average of 4–6 years with moderate daily wear (4–5 days per week). Longevity depends on exposure to sunlight, humidity, and frequency of use. A shell cordovan strap can last up to 8–10 years thanks to the density of equine leather. Regular maintenance—cleaning with a damp cloth, drying, and conditioning with specific creams every 6 months—significantly extends service life. Vegetable-tanned straps develop natural patina, making strap changes more an aesthetic choice than a necessity due to wear.
