The Portugieser IW3266-02 (aka: IW326602), seen from the bench

The 22mm lug width accommodates proportionate strap selection without oversizing the wrist.

Frequently asked questions

What is the exact lug width of the IWC Portugieser IW3266-02?

The Portugieser IW3266-02 features a lug width of 22mm. This is the standard measurement for watches of this style and is compatible with most straps manufactured to international specification. To verify correct compatibility, measure the horizontal space between the two lugs: a 22mm strap must sit flush within the lug attachment without forcing.

Which strap material is most suitable for the Portugieser IW3266-02?

For the Portugieser, we recommend alligator leather, which offers a natural grain in small squares conferring formal elegance, or vegetable-tanned calf leather, which develops a distinctive patina over time. Shell cordovan is the choice for purists: exceptionally rare horse leather that lasts years and absorbs sunlight, developing an increasingly fascinating colour. Your selection depends on your lifestyle: formal, versatile, or premium.

How do I change the strap on an IWC Portugieser?

Changing the strap is a straightforward operation requiring precision. Position the watch on a stable table with the case facing upwards. Use a dedicated tool (spring bar tool) to gently compress the small metal pins (spring bars) that retain the strap to the lugs. Upon compression, the strap will disengage easily. Repeat on the opposite side. Install the new strap by aligning its holes with the lugs and releasing pressure from the tool: you will hear a 'click' confirming correct positioning.

Can I install an aftermarket compatible strap on my Portugieser IW3266-02?

Yes, absolutely. Any strap featuring a 22mm lug width is compatible with the Portugieser IW3266-02. Artisanal high-quality straps, crafted in premium leather or technical textiles, frequently offer superior finishing and customisation compared to OEM straps. Ensure the strap has been constructed with precision and that the spring bars function perfectly.

How long does natural leather strap last on a watch worn daily?

The lifespan of a natural leather strap depends on usage intensity, climatic conditions and material choice. Vegetable-tanned calf, worn daily, typically lasts 3–5 years before replacement becomes necessary. Shell cordovan, thanks to its structural density, can last 7–10 years. Alligator settles at 5–7 years. These intervals extend significantly if the watch is not worn every day. Accelerated aging of leather is natural and desirable among many collectors, as it adds character and patina to the strap.
